ENGINE KEEPS GETTING OVER-HEATED EVEN AFTER A NEW ENGINE FAN HAS BEEN REPLACED. HOWEVER, AFTER ITS REPLACEMENT I TOOK IT TO TWO MERCEDES DEALERSHIP TO RE-INSPECT AND MAKE ADJUSTMENT TO THEIR INSTALLMENT OF THE FAN BUT IT KEEPS GETTING OVERHEATED. I ALSO HAD A NEW WATER COOLANT TANK INSTALLED BUT IT IS ALSO LEAKING OUT THE COOLANT AND SHOWING THE WARNING LIGHT. THESE EVENTS HAPPEN AFTER I TOP UP THE COOLANT TANK AND DRIVE AROUND 50 MILES, THEN THE OVERHEATING STARTS AND THE TANK STARTS BECOMING EMPTY.

LOSS OF POWER STEERING DRIVING ON THE FREEWAY DUE TO SUDDEN BREAK OF IDLER ARM PULLEY AND SUBSEQUENT SHREDDING OF BELT. PROBLEM IS THE PULLEY IS MADE OF PLASTIC AND CRACKED IN TWO, LEAVING 1/2 THE PULLEY AND SHREDDING THE BELT. THIS OCCURRED AT DRIVING SPEED OF 50 MPH AND MILEAGE AROUND 169,650 ON 2003 ML500. THIS WAS VERY DANGEROUS. I WAS ABLE TO PULL OFF THE FREEWAY AS I WAS DRIVING IN THE LANE NEAREST FREEWAY EXITS. ALMOST IMPOSSIBLE BUT ABLE TO STEER INTO A PARKING LOT. LUCKY IT WAS 'RUSH' HOUR AND TRAFFIC WAS SLOW ON SURFACE STREETS. INCREDIBLE SAFETY ISSUE DUE TO DIFFICULTY TO STEER WITHOUT POWER STEERING. CAR IS REGULARLY MAINTAINED BY GERMAN MECHANIC FAMILIAR WITH REPAIR OF MB ENGINES IN GERMANY.

Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The noise is heard once in each instance when changing direction of travel. Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to cracking of the microweld 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. See also LI33.20-P-078406 Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove side shafts 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") with 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).

Complaint Headlamp, front fog lamp leaky or fogged. Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps: 1. Drive vehicle into workshop (temperature higher than +18 °C/+64.4 °F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing of fogged/condensed LED headlamps and LED rear lamps on electric vehicles: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). 2. Connect battery backup via a charger. 3. Open the front-end flap and ensure sufficient ventilation. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in condensation, check the headlamp for malfunctions. (see Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Note: Only implement Remedy 1 for model series 463 (from model year 2018) and model series 465. Remedy 2 A defective headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness according to LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case. Note: With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. • Open ventilation system LI82.10-P-078302 • Closed ventilation system LI82.10-P-078304

Note: Sound file in attachment 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.
