The cam sensors on the mercedes M271 engine leak oil which spreads to other components via the wire harnesses connected to cam sensors. Oil contamination will damage other electrical components (namely the ecu and exhaust oxygen sensors) if the cam sensors and wire harnesses are not replaced. A new cam sensor and wire harness has been designed as the corrective action. The defective cam sensor and wire harness were used on the previous engine design (M111). There IS a technical service bulletin for M111 engine but not the M271 engine. Mercedes refuses to recall this defective design on the M271 engine causing owners to pay for the $900 preventative maintenance. Without this repair the ecu (part cost $2000) and oxygen sensors (qty 2 @ $238 ea) will be eventually damaged and will need to be removed and replaced. within the past week, paid more than $ 2,400.00 to replace 2 cam sensors, 2 oxygen sensors, and wiring harness. repair shop says that this IS a defect that mb has known about for years. *Tr

C230k coupe at 73,000 miles with sudden valve guides worn bad cylinder,compression loss recently in april I was called into mbz for a recall on a vacuum hose, here I am a few months later and I'm driving and my car starts shaking ,idling strange and then I take it to a mechanic and he figured it at first glance it may be worn valve gasket seals and I said ok let's change them and put in new plugs too...then he checks the compression and discovers that it IS half of what it should be, what? Why should the cylinder heads be worn and need to be replaced for nearly $3000, ...this seems to be happening too many owners of this model on here and mbzforums for this 2003-2005 years. Loss of compression in one or more cylinders. This should be recognized by mbz as a defect and since when do these engines fail at 50,000or even 80,000? I feel this should be paid for by them, this IS ridiculous and should not be happening at this mileage!! Defect,flaw in design...they need to step up and admit it at mercedes headquarters. please help us owners , they are getting away with this, mentioning vacuum hose recalls on this 2003 year but some dealers have recognized that these engines are defective and a recall needs to be done on these valve guides/cylinder heads. why IS it that there IS an inconsistency on how this problem IS recognized by the dealer and handled. Some on the forums have said that the dealer screwed them if the 50,000 warranty IS over and others have had the parts only paid for by the dealer and others have had the whole thing paid!! too many of these c230k engine cylinders/valve guides are going bad, they are defective and mbz should be correcting this. I should not pay $3000 to rebuild engine that has been maintained on schedule and for a car that IS at only 73,000 miles thanks *tr

Check engine light on, with occasional poor gas mileage, rough running. when engine starts rough, engine stop/re-start gets engine to idle/run properly. dealer reported cam solenoids leaking engine oil into the wiring harness shorting harness components (O2 sensors etc.), high $$$ repair. first occurrence at 57K miles (just out of warranty). contacted mb, no concern, too bad for you. sporadic red led warning about gas cap, blinking indicator in fuel gauge, stop/restart engine, goes away (error not in owners manual). car still running at 78K miles and usually 35 mpg during normal commute so far (without repair so far, do not have tail pipe emission check in area yet, so not mandated to fix mil light issue), clear ecm codes occasionally, come back after 3 key cycles. stuck with car that IS not worth fixing to have same problem come back. this cam solenoid/wiring harness/o2 sensor/check engine light issue should be resolved and paid for by mb since this IS known defect that severely reduces the drivablilty and value of the vehicle. *Tr

Check engine light came on. I took it to the dealer and they told me that the O2 sensor needs to be replaced, and the engine harness needs to be replaced. This IS because the cam sensor leaked and pushed oil inside the harness and now there IS oil flowing in the harness. This means everywhere there IS a contact of the harness there IS a possibility that there IS oil on it. This seems to have become a common issue now and mercedes IS ignoring it. I have noticed that I am getting bad mileage because of the bad O2 sensor. The irony IS that the dealer will fix it with the same exact part number only to have it leak again in 4 years. *Tr

- 11007974Complaint 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
- 11007753Complaint 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/+64.4F). 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
- 11005294Complaint 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).
