An authorized Mercedes-Benz dealer will check the ground and potential equalization connections on the affected vehicles and, if necessary, tighten them according to specifications. Prior to performing this Campaign:  VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns, and perform accordingly.  Please review the entire Campaign bulletin and follow the repair procedure exactly as described. Approximately 24 vehicles are affected. Order No. P-RC-2022030019 This bulletin has been created and maintained in accordance with MBUSA-SLP S423QH001, Document and Data Control, and MBUSA-SLP S424HH001, Control of Quality Record 2 P-RC-2022030019 Check threaded connection of ground points on front left longitudinal member, correct if necessary Model 297 Check/test procedure 1. Perform power disable for high-voltage on-board electrical system. For basic data, see AR47.70-P-1000EQS. 2. Remove air ducting from engine compartment. For basic data, see AR83.10-P-1411EQS, operation step 2.1. 3. Loosen the threaded connection of ground point “W92w2” of equipotential bonding line of high-voltage PTC heater (N33/14) for vehicle interior in area of inner front left longitudinal member and left spring dome and screw on correctly (figure 1). It is possible that the torque of the threaded connection may not have been tightened correctly and this could cause the threaded connection to loosen! When tightening the ground point “W92w2” of the equipotential bonding line, make sure that the contact surface of the threaded connection is clean and correct! Threaded connection of equipotential bonding line for the vehicle interior front left longitudinal member high-voltage PTC heater 7! Figure 1 4. Install air ducting from engine compartment. For basic data, see AR83.10-P-1411EQS, operation step 2.1. 5. Remove front left fender liner front section. For basic data, see AR88.10-P-1301EQS. 3 P-RC-2022030019 6. Check whether the threaded connection (A, figure 2 and 3) of the ground point “W52/8” has been installed correctly on the outer front left longitudinal member. It is possible that the threaded connection may be loose! The area of the threaded connection shall also be checked for traces of signs of electrical arcing or sparks! Figure 2 Figure 3 a. Arc/spark traces on threaded connections for ground point “W52/8” present: Perform work procedures A and B. b. Arc/spark traces on threaded connections for ground point “W52/8” not present: Perform work procedure B Work Procedure A 1. Remove ground line of ground point “W52/8”. 2. Eliminate traces of arcing/sparks on the ground point “W52/8”. Replace cable lug of ground line, to do this, see basic data under AR00.19-P-0100A. The corresponding cable lugs shall be determined according to the diameter of the diameter of the ground line! 3. Install ground line of ground point “W52/8”. Work Procedure B 1. Correct torque of threaded connections of ground point “W52/8”. Threaded connection of ground point “W52/8” outer front left longitudinal member 7! 2. Assemble in reverse order. 3. Perform commissioning of the high-voltage on-board electrical system. For basic data, see AR47.70-P-1000EQS. __________________________________________________________________________________________________ 4 P-RC-2022030019 Primary Parts Information Qty.
