SummaryComplaint Noises/ squealing from the service brake in various driving situations and ambient conditions. Cause Frictional vibrations Remedy AMG brake systems are designed for high loads. This can result in noises under certain operating conditions and driving styles. Please refer to the Operator's Manual for further information such as care and maintenance instructions (washing vehicle directly after heavy use and using approved cleaning agents). These are dependent on speed, brake pressure or ambient conditions such as temperature and air humidity. 1. Beginning Diagnostics: a) Check whether the complaint can be reproduced and at which axle or side the noises occur (ideally together with the customer while driving). b) Check the affected system for component wear, mechanical damage or localized overheating damage. Replace damaged components as necessary. c) Assess condition of brake rotors and pads per WIS and visually (i.e. long periods of stagnation, etc...). d) Clean brake components free of brake dust and debris. d) Secure vehicle on a lift. 1. Start the engine and depress the brake pedal 3-4 times. 2. Check each wheel to see if they turn freely by hand. 3. If a wheel is not turning freely by hand, this needs to be addressed prior to re-assessing the noise concern. e) Check whether, apart from this document, an additional document exists for the specific model in question, and if so, work through it and then continue. 2. Specific Axle Work: NOTE: If the brake pad has a metal backing plate, there is no need to affix the adhesive film. a) If the noises are coming from the front axle => Affix linings with adhesive film (see attachments for front axle). If backing plate is installed on pads, move to step 3. 1. Remove brake linings of front axle. 2. Clean all contact points on brake lining and brake caliper/carrier. 3. Clean bonding surface (where pistons contact back of brake pad). Apply adhesive film to the backplate of the piston-side brake lining where the piston contacts the pad backing plate. See picture "Adhesive and Paste Application Area". 4. Chamfer edges (round off sharp leading edges) on brake pads. See picture "Chamfered Pads". 5. Apply heat-resistant lubricating paste to the sides of the backing plate. See picture "Adhesive and Paste Application Area". 6. After installing the brake linings, actuate the brake for 30 seconds. b) If the noises are coming from the rear axle => Affix linings with adhesive film and grease the lining as per the specification (see attachments for rear axle). 1. Remove brake pads of rear axle. 2. Cleaning all contact points on brake lining and brake caliper/carrier. 3. Grease contact points (red areas) between brake lining and guide of brake caliper with heat-resistant lubricating paste. 4. Clean bonding surface (where pistons contact back of brake pad). Apply adhesive film to the backplate of the piston-side brake lining. 5. Chamfer edges (round off sharp leading edges) on brake pads. See picture "Chamfered Pads". IMPORTANT: Be absolutely certain to not allow paste between friction surfaces of the pad and disc! 3. Brake Bedding Process: a) Before trip, the mileage incurred must be clarified with the customer (approx. 30 miles). b) Select a suitable route so speeds of approximately 65 MPH can be achieved. c) If the vehicle is an AMG P3 Hybrid, switch off recouperation prior to bedding in brakes. d) Brake the vehicle 15 times with a brake pressure of approx. 30 bar (have the passenger read it out using XENTRY) from 62 MPH to 30 MPH (no emergency stops and no braking in the ESP control range). Maintain a cooling distance of approx. 1 mile between brake applications. e) Finally drive approx. 3 miles to allow the system to cool. f) Reassess noise.

SummaryComplaint Vehicle with atypical reduced heat output. Cause Silicate granulate may have escaped from a damaged bag in the expansion reservoir (not visible), reducing the coolant flow in the heater heat exchanger (see picture). Remedy With the aforementioned complaint, make sure that the cooling circuit is inspected for silicate residues after all standard tests are completed. The silicate residues tend to accumulate upstream of the shutoff valve for the heater hot water pulsed valve. If there are silicate residues in the coolant, the engine must be flushed thoroughly. To make sure that all silicate residues are removed from the cooling circuit, the following parts must also be replaced (cleaning of these components is not sufficient): Coolant expansion reservoir, radiator, oil/water heat exchanger (oil cooler), heater valve, heat exchanger of heater, coolant and, if installed, the electric water pump for the residual heat utilization system. Determine the parts for the respective vehicle in the EPC.

SummaryComplaint The flap of the reversing camera opens and closes by itself during forward travel several times during the trip. No camera image is displayed in the head unit. The reversing camera or the 360° system functions normally when activated manually or by engaging drive range "R". Cause This is not a malfunction, but an intended system behavior. Calibration of the reversing camera is in progress. The calibration is completed by: • Opening the camera cover for a maximum of 5 cumulative minutes. • If the vehicle speed is < 35 km/h (<22 MPH). • The steering wheel angle is < 10°. If calibration is aborted by exceeding one of the above conditions, the camera retracts and the calibration will re-attempt once the conditions are achieved and the speed returns to the range of 18 km/h (~11 MPH). Remedy SCN code PARK213M on MFA2 facelift vehicles produced after 09/2024 (A-Class, CLA, GLA, etc...) so the complete calibration speed window is available. For vehicles with PARK213M or PARK223 a calibration is completed successfully by: • Driving forward (typically less than 1 minute). • Vehicle speed is < 35 km/h (<22 MPH). • The steering wheel angle is < 10°. • During daylight. • Without a vehicle following too closely (camera must be able to see asphalt). When calibration has completed successfully, the camera door closes automatically for the rest of the driving cycle. The camera will now only open if the customer requests (Example: Engaging reverse gear). The calibration of the camera will re-initiate every drive cycle (ignition change). The customer can generally perform calibration at the first attempt while briefly maintaining a speed range of 15 km/ h (~9 MPH) and 35 km/h (~22 MPH). The customer can therefore play a significant role in reducing the camera door noise and actuation frequency.

SummaryComplaint Fuel door may require several attempts to open. Please note that if the complaint "Fuel filler flap not opening" occurs, it is important to check the fuel filler flap before replacing the central locking actuator. For gasoline hybrid vehicles where the fuel filler flap fails to open or does so but slowly, observe the document "Fuel filler flap fails to open or does so but slowly on plug-in HYBRID gasoline vehicles"! Cause Central locking actuator may have an electrical fault and may not open. Remedy 1. Car locked: To rule out incorrect operation, operate the fuel filler flap in the area shown in Fig. 1 and listen out for the clicking noise of the microswitch in the central locking actuator. If no clicking can be heard, continue with point 4. 2. Car unlocked: Press area on flap to start the microswitch clicking. Flap opens - show the customer the area to press. 3. Car unlocked: Flap cannot be opened regardless of which area you press. Open the flap by operating the emergency release for the CL actuator (through trunk, fender gap cover, etc, depending on specific vehicle) 4. Central locking actuator pressed directly, no clicking of microswitch, no electrical release of central locking actuator => Clicking of microswitch, electrical release of central locking actuator => Tank filler recess/charging recess not OK; report results via a TIPS case to B/C/E Inbox. 5. Replace central locking actuator; check function of new part before installing it: Do not dispose of damaged part. New central locking actuator does not release: More detailed examination of connector coupling, wiring harness, electrics required.

SummaryComplaint Noises/ squealing from the service brake in various driving situations and ambient conditions. Cause Frictional vibrations Remedy AMG brake systems are designed for high loads. This can result in noises under certain operating conditions and driving styles. Please refer to the Operator's Manual for further information such as care and maintenance instructions (washing vehicle directly after heavy use and using approved cleaning agents). These are dependent on speed, brake pressure or ambient conditions such as temperature and air humidity. 1. Beginning Diagnostics: a) Check whether, apart from this document, an additional document exists for the model series in question, and if so, work through it and then continue with1b. b) Check whether the complaint can be reproduced and at which axle or side the noises occur (ideally together with the customer while driving). c) Check the affected system for component wear, mechanical damage or localized overheating damage. 1. Replace damaged components as necessary and re-assess noise concern. d) Secure vehicle on a lift. 1. Start the engine and depress the brake pedal 3-4 times. 2. Check each wheel to see if they turn freely by hand. 3. If a wheel is not turning freely by hand, this needs to be addressed prior to re-assessing the noise concern. e) Assess condition of brake rotors and pads per WIS and visually (i.e. long periods of stagnation, etc...). 2. Specific Axle Work: NOTE: If brake pad has a metal backing plate, there is no need to affix the adhesive film. a) If the noises are coming from the front axle => Affix linings with adhesive film (see attachments for front axle). If backing plate is installed on pads, move to step 3. 1. Remove brake linings of front axle. 2. Clean all contact points on brake lining and brake caliper/carrier. 3. Clean bonding surface (where pistons contact back of brake pad). Apply adhesive film to the backplate of the piston-side brake lining. For 6 piston calipers, only in the area of the center piston. For other piston caliper configurations less than 6, apply where the piston(s) makes contact with the back of the pad. 4. After installing the brake linings, actuate the brake for 30 seconds. b) If the noises are coming from the rear axle => Affix linings with adhesive film and grease the lining as per the specification (see attachments for rear axle). 1. Remove brake pads of rear axle. 2. Cleaning all contact points on brake lining and brake caliper/carrier. 3. Grease contact points (red areas) between brake lining and guide of brake caliper with heat-resistant lubricating paste. 4. Clean bonding surface (where pistons contact back of brake pad). Apply adhesive film to the backplate of the piston-side brake lining. IMPORTANT: Be absolutely certain to not allow paste between friction surfaces of the pad and disc! 3. Brake Bedding Process: a) Before trip, the mileage incurred must be clarified with the customer (approx. 30 miles). b) Select a suitable route so speeds of approximately 65 MPH can be achieved. c) Brake the vehicle 15 times with a brake pressure of approx. 30 bar (have the passenger read it out using XENTRY) from 62 MPH to 30 MPH (no emergency stops and no braking in the ESP control range). Maintain a cooling distance of approx. 1 mile between brake applications. d) Finally drive approx. 3 miles to allow the system to cool. e) Reassess noise.

SummaryComplaint Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The clunk is heard once when changing from forward to reverse (and vice versa). Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to micromovement in the connection between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened and must be tightened to the specified torque. Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove outboard side shafts (extract outer joint gearing from wheel hub) 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") using Molykote and leave to dry for one hour in removed condition 4. Reinstall side shafts Note: Before using the antifriction coating (Molykote), stir it or shake it thoroughly for (at least 1 minute).
