DEALER FAQs
What is the reason for this Emission Modification?
On March 9, 2021, Daimler AG (“DAG”) and Mercedes-Benz USA, LLC (“MBUSA”) reached a settlement with the United States Department of Justice (“DOJ”), the Environmental Protection Agency (“EPA”), the California Air Resources Board (“CARB”), and the California Attorney General’s Office (“CA AG”) regarding the emission control system in MY09 to MY16 OM642 and OM651 BlueTEC II diesel vehicles sold or leased in the US. As part of this settlement, MBUSA is offering eligible Owners and Lessees a modification to the vehicles’ emission control system, referred to as an Emission Modification.
Eligible vehicles and vehicle model years have been separated into Emission Modification Categories (“EMCs”) to facilitate the Emission Modification Program. Each EMC will be launched in phases, and MBUSA will notify authorized Mercedes-Benz Dealers after agency approval of each Emission Modification. Please refer to our public website https://BlueTecUpdate.mbusa.com for more information on your particular vehicle.
Is this a recall?
No, this is NOT a recall. As part of the settlement with the US authorities, DAG and MBUSA are offering eligible vehicle Owners/Lessees a modification to the vehicles’ emission control system, referred to as an Approved Emission Modification (AEM). This modification will be performed at no cost to the Owner/Lessee.
What is an “EMC”?
To facilitate the Emission Modifications on the subject vehicle population, the vehicle models and model years have been separated into Emission Modification Categories.
What are the eligible vehicles that will receive an Emission Modification under this settlement?
This settlement pertains specifically to MY09 to MY16 BlueTEC II diesel vehicles with OM642 and OM651 engines sold or leased in the US. For more information, please visit https://BlueTecUpdate.mbusa.com.
How will the Emission Modification be communicated to Owners and Lessees in the US?
Owners/Lessees will first receive a letter in the mail indicating that the Emission Modification is available for their vehicle and inviting them to schedule an appointment with their preferred authorized Mercedes-Benz Dealer.
How do Owners and Lessees find out whether their vehicle is affected by the Emission Modification Campaign?
Owners and Lessees with affected vehicles will be mailed a notification letter when the Emission Modification is available. Owners and Lessees can also check if their vehicle is affected by entering their VIN into the following site:
All vehicles covered by the Emission Modification Program also are covered by the proposed class action settlement described herein.
Owners and Lessees might complain about a Check Engine light; will the Dealer repair the vehicle as part of the emissions update?
A Check Engine light can illuminate for a number of reasons. Authorized Mercedes-Benz Dealers can offer assistance diagnosing and repairing the issue.
Can an Owner or Lessee get a loaner vehicle or alternate transportation while the Emission Modification is being performed?
Where loaner vehicles are available, Dealers are requested to offer loaner vehicles to each Eligible Owner and Eligible Lessee at no cost where the implementation of the Approved Emission Modification will take 3 hours or longer to complete.
In an instance where the Approved Emission Modification takes 3 hours or longer to complete, and where the Dealer does not make available a loaner car or offer a shuttle service or alternative transportation, Class Members will be eligible to submit a claim for transportation costs of up to $35 along with their claims for other settlement compensation. For more information on the transportation allowance, customers should visit the class action settlement website at www.mbbluetecsettlement.com, and should be reminded to save their receipts.
What is Mercedes-Benz going to do for Owners and Lessees given this inconvenience?
Dealers will attempt to minimize any inconvenience during the Emission Modification process. Should Owners or Lessees experience an excessive delay with the Emission Modification of their vehicle, they can contact our Customer Assistance Center at 1-833-841-9362.
As part of the proposed consumer class action resolution, current owners and lessees of eligible vehicles who go to authorized Mercedes-Benz Dealers, have an Approved Emission Modification installed, and meet certain other requirements will be eligible to claim a payment of up to $3,590. For more information on eligibility and the process for filing a claim, customers should call the number above or visit the class action settlement website at www.mbbluetecsettlement.com.
Other than the benefits that class members can claim through the class action settlement process, customers cannot be offered any compensation in exchange for receiving the Emission Modification. Failure to adhere to this instruction may result in possible penalties. At their discretion and on a case-by-case basis, Dealers can continue to offer customers goodwill for other reasons consistent with normal business practices and policies, but additional compensation in exchange for receiving the Emission Modification is prohibited.
Where can an Owner or Lessee have the Emission Modification work completed?
Owners and Lessees will be asked to contact their local preferred authorized Mercedes-Benz Dealer to arrange for an appointment to complete the FREE Emission Modification.
Can Owners and Lessees have the Emission Modification performed if they did not receive a Notification Letter in the mail but own a Mercedes-Benz BlueTEC diesel vehicle?
Owners and Lessees should first check the eligibility and status of their vehicle by visiting https://BlueTecUpdate.mbusa.com. To be automatically alerted when the Emission Modification is available for their vehicle, Owners and Lessees are being asked to complete the “Keep me Updated” section of the website after entering their VIN to check the status.
Do Owners and Lessees have to wait for the notification letter in the mail before their vehicle can receive the Emissions Modification?
Owners and Lessees do not need to present a copy of the notification letter to receive the FREE Emission Modification, but they should wait to bring their vehicle in for the Emission Modification until they receive notice that the Emission Modification has been launched for their specific vehicle model. The Emission Modifications will be launched in phases, pending agency approval, so the Emission Modifications for all of the subject vehicle models (all MY09 to MY16 BlueTEC II diesel vehicles with OM642 and OM651 engines sold or leased in the US) will not be launched at the same time. Once the Emission Modification has been approved for a particular vehicle type, Owners and Lessees will be sent a letter asking them to schedule an appointment with their authorized Mercedes-Benz Dealer to perform the FREE Emission Modification.
Do Owners or Lessees need the Owner/Lessee notification letter to have the Emission Modification performed?
No, Owners and Lessees with eligible vehicles do not need the notification letter to have the FREE Emission Modification completed. Local authorized Mercedes-Benz Dealers can check the eligibility and status of vehicles without the letter.
What about Owners or Lessees who request that the Emission Modification be performed without first receiving a letter?
No Emission Modification can be performed until EPA and CARB approve the Emission Modification for the specific model. Similarly, the affected VIN must be flagged as “OPEN” in VMI with the respective Emission Modification campaign number for the modification to be performed.
When will parts be available?
Parts are currently available for the Emission Modifications which have been approved by EPA and CARB. We will provide updates as parts become available for other vehicle models.
Regarding all other future vehicle categories, MBUSA is working with EPA and CARB to obtain approvals for the Emission Modification. MBUSA will notify Dealers upon approval of each Emission Modification that the Emission Modification has become available.
For up-to-date parts availability information, please refer to the website https://BlueTecUpdate.mbusa.com.
Are there any known vehicle symptoms associated with the Emission Modification that Owners or Lessees will notice that should lead them to stop driving or take their vehicle to a Dealer?
No. There are no symptoms related to the Emission Modification.
What is the expected impact on an Owner’s or Lessee’s vehicle after the Emission Modification has been performed?
Details on the impact to vehicles are provided in the letter for each Emission Modification Category. A copy of the Owner/Lessee letter for the EMC subject to this FAQ is attached.
What types of repairs or replacements are needed?
Authorized Mercedes-Benz Dealers will replace specific emissions-related components. This varies by model and model year. For more information, please visit https://BlueTecUpdate.mbusa.com.
How long does this Emission Modification take?
Replacement time is dependent upon the model and model year. This time may range from 30 minutes to a maximum of 16.5 hours. Details are provided in the Owner/Lessee notification letter.
What if vehicles have been modified using after-market parts and/or software? Can the Emission Modification still be performed?
If, prior to receiving the Emission Modification, the vehicle has been modified in a manner that impedes the installation of the AEM or substantially affects the operation of the AEM after install (for example, removal of original emissions components not part of the AEM), dealers might not be able to perform the Emission Modification until the prior modifications are corrected. The Owners/Lessees would be responsible for such corrections. Once corrected, the vehicle may receive the Emission Modification.
What if Owners or Lessees decline to have the Emission Modification performed?
If Owners/Lessees decline the Emission Modification at this time, they will be advised by their authorized MercedesBenz Dealer that certain emissions-related replacement and repair parts (for their existing system) may no longer be available from Mercedes-Benz at some point in the future. Additionally, the current vehicle Owner/Lessee will not be able to make a compensation claim as part of the proposed class action settlement without first having the Emission Modification performed on their vehicle.
Will eligible vehicles have any warranty on the Emission Modification?
Yes. Once the Emission Modification is performed, certain components will have an extended warranty for the greater of 4 years/48,000 miles from the date of installation of the Emission Modification or 10 years/120,000 miles from the initial sale date of the vehicle. As described in the Customer Letter, some emission-related components have an additional extended warranty period, which is added to the applicable Extended Modification Warranty period above. This extended warranty remains with the vehicle and is fully transferable to subsequent owners until expiration. Where loaner vehicles are available, Dealers are requested to offer loaner vehicles to each Eligible Owner and Eligible Lessee at no cost where extended warranty repairs exceed three hours to complete.
Can Owners or Lessees be denied coverage under the Extended Warranty for the Emission Modification? The Extended Warranty for the Emission Modification may be denied if an eligible vehicle has been altered with the use of any after-market emissions-related components, parts, and/or software, or with the removal of any original emissions-related components, parts, and/or software, and such alteration(s) are likely to substantially affect the operation of the vehicle with the Emission Modifications, until the owner of such vehicle, at his or her expense, has reversed the alteration(s) such that the Emission Modification will not be substantially affected.

A Check Engine light can illuminate for a number of reasons. Authorized Mercedes-Benz Dealers can offer assistance diagnosing and repairing the issue. Can an Owner or Lessee get a loaner vehicle or alternate transportation while the Emission Modification is being performed? Where loaner vehicles are available, Dealers are requested to offer loaner vehicles to each Eligible Owner and Eligible Lessee at no cost where the implementation of the Approved Emission Modification will take 3 hours or longer to complete. In an instance where the Approved Emission Modification takes 3 hours or longer to complete, and where the Dealer does not make available a loaner car or offer a shuttle service or alternative transportation, Class Members will be eligible to submit a claim for transportation costs of up to $35 along with their claims for other settlement compensation.

To be automatically alerted when the Emission Modification is available for their vehicle, Owners and Lessees are being asked to complete the “Keep me Updated” section of the website after entering their VIN to check the status. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis Do Owners and Lessees have to wait for the notification letter in the mail before their vehicle can receive the Emissions Modification? Owners and Lessees do not need to present a copy of the notification letter to receive the FREE Emission Modification, but they should wait to bring their vehicle in for the Emission Modification until they receive notice that the Emission Modification has been launched for their specific vehicle model. The Emission Modifications will be launched in phases, pending agency approval, so the Emission Modifications for all of the subject vehicle models (all MY09 to MY16 BlueTEC II diesel vehicles with OM642 and OM651 engines sold or leased in the US) will not be launched at the same time. Once the Emission Modification has been approved for a particular vehicle type, Owners and Lessees will be sent a letter asking them to schedule an appointment with their authorized Mercedes-Benz Dealer to perform the FREE Emission Modification. Do Owners or Lessees need the Owner/Lessee notification letter to have the Emission Modification performed? No, Owners and Lessees with eligible vehicles do not need the notification letter to have the FREE Emission Modification completed. Local authorized Mercedes-Benz Dealers can check the eligibility and status of vehicles without the letter. What about Owners or Lessees who request that the Emission Modification be performed without first receiving a letter? No Emission Modification can be performed until EPA and CARB approve the Emission Modification for the specific model. Similarly, the affected VIN must be flagged as “OPEN” in VMI with the respective Emission Modification campaign number for the modification to be performed. When will parts be available? Parts are currently available for the Emission Modifications which have been approved by EPA and CARB. We will provide updates as parts become available for other vehicle models. Regarding all other future vehicle categories, MBUSA is working with EPA and CARB to obtain approvals for the Emission Modification. MBUSA will notify Dealers upon approval of each Emission Modification that the Emission Modification has become available. For up-to-date parts availability information, please refer to the website https://BlueTecUpdate.mbusa.com. Are there any known vehicle symptoms associated with the Emission Modification that Owners or Lessees will notice that should lead them to stop driving or take their vehicle to a Dealer? No. There are no symptoms related to the Emission Modification. What is the expected impact on an Owner’s or Lessee’s vehicle after the Emission Modification has been performed? Details on the impact to vehicles are provided in the letter for each Emission Modification Category. A copy of the Owner/Lessee letter for the EMC subject to this FAQ is attached. What types of repairs or replacements are needed? Authorized Mercedes-Benz Dealers will replace specific emissions-related components. This varies by model and model year. For more information, please visit https://BlueTecUpdate.mbusa.com. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis How long does this Emission Modification take? Replacement time is dependent upon the model and model year. This time may range from 30 minutes to a maximum of 16.5 hours. Details are provided in the Owner/Lessee notification letter. What if vehicles have been modified using after-market parts and/or software? Can the Emission Modification still be performed? If, prior to receiving the Emission Modification, the vehicle has been modified in a manner that impedes the installation of the AEM or substantially affects the operation of the AEM after install (for example, removal of original emissions components not part of the AEM), dealers might not be able to perform the Emission Modification until the prior modifications are corrected. The Owners/Lessees would be responsible for such corrections. Once corrected, the vehicle may receive the Emission Modification. What if Owners or Lessees decline to have the Emission Modification performed? If Owners/Lessees decline the Emission Modification at this time, they will be advised by their authorized Mercedes-Benz Dealer that certain emissions-related replacement and repair parts (for their existing system) may no longer be available from Mercedes-Benz at some point in the future. Additionally, the current vehicle Owner/Lessee will not be able to make a compensation claim as part of the proposed class action settlement without first having the Emission Modification performed on their vehicle. Will eligible vehicles have any warranty on the Emission Modification? Yes. Once the Emission Modification is performed, certain components will have an extended warranty for the greater of 4 years/48,000 miles from the date of installation of the Emission Modification or 10 years/120,000 miles from the initial sale date of the vehicle. As described in the Customer Letter, some emission-related components have an additional extended warranty period, which is added to the applicable Extended Modification Warranty period above. This extended warranty remains with the vehicle and is fully transferable to subsequent owners until expiration. Where loaner vehicles are available, Dealers are requested to offer loaner vehicles to each Eligible Owner and Eligible Lessee at no cost where extended warranty repairs exceed three hours to complete. Can Owners or Lessees be denied coverage under the Extended Warranty for the Emission Modification? The Extended Warranty for the Emission Modification may be denied if an eligible vehicle has been altered with the use of any after-market emissions-related components, parts, and/or software, or with the removal of any original emissions-related components, parts, and/or software, and such alteration(s) are likely to substantially affect the operation of the vehicle with the Emission Modifications, until the owner of such vehicle, at his or her expense, has reversed the alteration(s) such that the Emission Modification will not be substantially affected.

Figure 6 7 P-EC-2020050022 6. Replace the DEF injection nozzle (A 164 490 26 00 80). For basic data see (AR14.40-P-2000GZB). The DTC memory does not have to be read out and deleted. 7. Connect the ground line of the battery. For basic data, see (AR54.10-P-0003GZ). 8. Check fuse F119 for presence in the fuse and relay box (F58) in the engine compartment on the right and remove if necessary. If this fuse is plugged in, it must be removed before the software update. The fuse must not be plugged in again and has to be disposed. 9. Connect XENTRY Diagnosis. 10. Perform XENTRY Procedure: Service Measure “Exhaust Aftertreatment System” (includes update of CDI, VGS, and SCR software) Select menu item “Main groups Control units Drive CDI 6-Common Rail Diesel Injection Special procedures Perform Service Measure “Exhaust aftertreatment system”. Then follow the user guidance in XENTRY Diagnosis. In the background, additional control units may be automatically updated. 8 P-EC-2020050022 9 P-EC-2020050022 11. Replace the engine control unit (A 642 900 98 01). For basic data see (AR07.08-P-7008GZB). 10 P-EC-2020050022 11 P-EC-2020050022 12. Clean the bonding surface of the hood and attach the adhesive label (A 000 584 64 15) (Figure 7). The fields on the adhesive label must be filled out correctly. Please use black permanent marker. Refer to (Figure 7) within the XENTRY procedure. The adhesive label can be applied to the hood while updating the software for the engine control unit. Failure to comply may result in dealer debit and/or possible fines. Figure 7 13. Complete XENTRY Diagnosis. 14. Perform a final quick test and transmit to paperless SDS. Faults stored in the memory, caused by disconnected lines during the inspections, must be deleted from the DTC memory after completing the work. If faults are present they need to be addressed. Create a PTSS case if technical support is needed. 12 P-EC-2020050022 Primary Parts Information Qty.
