WE JUST PURCHASED A 2002 MERCEDES BENZ CLK 430. FOR BARELY TWO WEEKS AND CAN'T DRIVE IT. WE ARE HAVING MAJOR ISSUE WITH THE TRUNK TO OPEN BECAUSE OUR BATTERY IS TOTALLY DEAD. WE CANNOT JUMP CABLE THE CAR BECAUSE THE BATERY IS IN THE TRUNK AND THE TRUNK WILL NOT EVEN OPEN WITH THE MANUAL KEY THAT IT COMES WITH. I HAVE CALLED MERCEDES BENZ AND DO EXACTLY WHAT I WAS ASK TO DO BUT STILL DIDNT WORK. I WENT ON YOU TUBE, GOOGLE, AND SEARCH THE INTERNET FOR ANSWERS BUT NOTHING. A LOT OF PEOPLE ARE HAVING THE SAME ISSUE WITH THEIR CLK'S CONVERTIBLE. IT SEEMS LIKE THIS IS A MANUFACTURER AND A DEFECTIVE MERCHANDISE. THIS IS A BIG DISAPPOINTMENT FROM THE MAKER AND THAT WAS UNEXPECTED. *TR

I OWN A 2001 MERCEDES-BENZ CLK430. I HAVE BEEN EXPERIENCING INTERMITTENT SPORADIC FAILURE OF THE ABS, BAS, ESP SYSTEMS WHEN I APPLY THE BRAKE. ON OCCASIONS THE GAS PEDAL STICKS AND THE CAR SPEEDS UP TO DANGEROUS SPEED. THE CAR HAS TO BE PUT IN NEUTRAL AND ONCE STOP AND RESTART, IT WOULD RUN NORMAL AGAIN, AND THE CAR SHOWS "NO MALFUNCTION". RECENTLY ON JULY OF 2013, WHILE I WAS DRIVING ON THE FREEWAY AND THE CAR SPED UP ON IT OWN AND ALMOST WENT OUT OF CONTROL. WHEN I APPLY THE BRAKE ABS/BAS/ESP REPORTED AS FAILED, BUT THE CAR DID STOP WHEN I PUT IN NEUTRAL AND APPLY THE BRAKE. I TOOK TO MERCEDES-BENZ AND THEY SAID THEY DON'T SEE ANY PROBLEM. I TOLD THEM I WANT THEM TO RUN THE "COMPUTER DIAGNOSIS" AND I WANT THEM TO GIVE ME THE REPORT. BELOW ARE A FEW OF THE SAFETY SYSTEM FAILURES THAT ARE ON THE REPORT: ETC - ELECTRONIC TRANSMISSION CONTROL CODE 120 THE FRONT RIGHT WHEEL SPEED OF THE TRACTION SYSTEM IS SPORADICALLY IMPLAUSIBLE CODE 121 THE FRONT LEFT WHEEL SPEED OF THE TRACTION SYSTEM IS SPORADICALLY IMPLAUSIBLE ME2-SFI - MOTOR ELECTRONICS 2.8 CODE P20DD-001 B37 (ACCELERATOR PEDAL SENSOR) : SIGNAL 1 / SHORT CIRCUIT TO POSSITIVE / POTENTIONMETER ABOVE MAXIMUM VALUE (P0123) ESP - ELECTRONIC STABILITY PROGRAM CODE C1504-009 THE SYSTEM IS SWITCHED OFF. CODE C1100-001 L6/1 (LEFT FRONT SPEED SENSOR) CODE C1101-001 L6/2 (RIGHT FRONT SPEED SENSOR) EZS - ELECTRONIC IGNITION SWITCH CODE B1156-005 THE CONTROL UNIT HAS SHORT CIRCUIT TO GROUND OR OPEN CIRCUIT. TELE AID [USA] - TELEMATIC SYSTEM CODE N1100 NO SIGNAL IS RECEIVED FROM THE RIGHT-SIDE SPEED SENSORS. CODE N1101 NO SIGNAL IS RECEIVED FROM THE LEFT-SIDE SPEED SENSORS. I SEARCHED ON GOOGLE AND FOUND MANY OWNERS REPORTED PROBLEMS WITH THEIR ABS/BAS/ESP SYSTEMS WITH CLK430 ON WWW.MBWORLD.ORG I BELIEVE THESE ARE MANUFACTURING DEFECTS AND MERCEDES SHOULD RECALL THE CLK430 AND FIX THE ISSUES. *TR

THE INSTRUMENT CLUSTER LED PROBLEM WITH MY 2000 MERCEDES CLK 430 HAS BECOME MORE OF A PROBLEM WITHIN THE PAST MONTH. IT HAPPENS QUITE FREQUENTLY NOW. WHENEVER I START THE VEHICLE, THE GEAR INDICATOR DOES NOT INDICATE WHICH GEAR I'M IN AND THE CAR PROCEEDS IN LOW MODE UNTIL I PULL OVER AND RESTART IT. THE SAFETY HAZARD LIES IN THE FACT THAT I DON'T CHECK MY GEAR INDICATOR CONSTANTLY, SO IF IT FAILS AND I DON'T NOTICE, THE LOW/SLOW MODE THAT THE CAR AUTOMATICALLY SHIFTS INTO COULD GET ME KILLED ON ANY STREET WHERE THE SPEED LIMIT IS AT LEAST 35. THIS CAR HAS GIVEN ME NUMEROUS PROBLEMS THE PAST YEAR AND MY SAFETY SEEMS TO BE IN JEOPARDY MORE AND MORE AS THE THESE ISSUES INCREASE IN SEVERITY. I MADE THE FINANCIAL SACRIFICE FOR THIS CAR BECAUSE MERCEDES ARE SUPPOSE TO BE SOME OF THE SAFEST VEHICLES ON THE ROAD......IT'S UNFORTUNATE THAT CONSUMERS IN MY SITUATION DON'T HAVE A VOICE WHEN WE'RE SIMPLY INNOCENT VICTIMS IN THE MAKING. *TR

Note: Repair kits for washer line hoses do exist to allow patches for line damage.

Complaint During a phone call, the called party has difficulty understanding/cannot understand the driver, or interference/background noises are audible to the called party during a call. It becomes increasingly difficult to understand as the speed rises. Cause A. Seating of the microphones in the headliner. Side edges are covered by the textile cover (see picture "1") B. Assembly of microphones (B25/20 or B25/21) in the headliner. C. Dirt inside the microphone housing Remedy 1. Press finger on rear of microphone (on adhesive tape) 2. Remove microphone cap from the front 3. Eliminate protruding material residues of the microphone cutout at the headliner, e.g. with a soldering iron. The microphone must be seated in the headliner as shown in picture "2". 4. Push microphone from behind until it is firmly pressed into the headliner 5. Maintain pressure and press/clip cap into microphone from the front. Note: The cover cap must be clearly heard and felt to engage. 6. This procedure must be carried out on both microphones (B25/20 and B25/21) Note: • It is recommended to replace the cover caps. • The non-woven cloth in the cover cap protects the microphone from soiling and must not be removed.

Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy In advance, observe LI82.10-P-078301 "Headlamps or Front Fog Lamps Leaking or Fogged". 1. Prepare headlamp/check for external damage: For headlamps with a closed system 1. Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. 2. If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system 1. Check the headlamps for any external damage and seal off the vent then make sure the cover caps are latched correctly into place. 2. If the headlamp exhibits any external damage, replace the headlamp. Note: A headlamp with external damage is not a warranty or goodwill case. 2. Leak test of headlamp with overpressure: • Connect test adapter to pressure tester. (Figure 1) • Check test adapter for leak tightness. To do so, connect plug and coupling (picture 2) and apply a maximum overpressure of 30 mbar. The pressure must remain constant. If the pressure does not remain constant, use a new adapter. • Seal all the outlet openings using sealing compound and the given diaphragm with the plunger (picture 3). (Picture 4) Make allowance for the different headlamp variants here (there are different outlet openings). • Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. • Plug the adapter onto the diagnostic socket on the headlamp housing. (Picture 5). • Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged. • If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is not leaky and the problem is down to natural physical fogging. • If a pressure drop of more than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. Replace any leaky headlamps. Note: Desiccant packs can be installed for headlamps that are not leaky. See: • LI82.10-P-064766 Fogged headlamp, desiccant pack installed - open ventilation system • LI82.10-P-078304 Fogged headlamp, desiccant pack installed - closed ventilation system

Complaint Headlamp or 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. Headlamps comply with all applicable standards. 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 and LED rear lamps: 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 or trunk. 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 the formation of condensation, check the headlamp for a defect. (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. Remedy 2 A Damaged 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 in accordance with 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. With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. Open ventilation system: LI82.10-P-064766. Closed ventilation system LI82.10-P-078304

Complaint Rear lamps fogged up/not leaktight. Cause Fogging of the rear lamps is a natural phenomenon, which can occur under certain climatic conditions. This does not lead to any technical impairment of the rear lamps. Remedy Rear lamp: Remedy 1: Clearing fogged/condensed rear lamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4 °F) Note: Do not wash the vehicle or subject it to high-pressure cleaning before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the trunk. 4. Switch on the exterior lighting. 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 (defogging progress).

Crease formation on genuine leather seat covers in vehicles with low mileage • Objects left on the seats for extended periods of time (pressure marks). • Objects wedged between the seat backrest and seat cushion (e.g. seat belt buckle). • Light initial creases due to vehicle handling. • Light creases in the outer covers originating from the production process (missing finish). Heat treatment of the seat covers using heat gun and plastic wedge. Be very careful to not overheat the seat material!
