Camshaft adjuster solenoid both sides. Mercedes Benz need to be responsible for this repair is apparent that this is a manufacture issue... Take your vehicle to the MB dealer near you.. call them with your Vin number and ask for an appointment to repair this.. there is a service campaing that came out in July 2012 to repair this problem... The dealers will fix this for free.. is similar to a recall... Good Luck everyone..
Check engine light came with codes 0060 and 0272 which according to my certified Mercedes mechanic and the report show to me from Mercedes that I have worn sprocket on my crank due the metal timing chain getting lose. One of the reason I purchased this car is that it had a metal timing chain that should last at least 200k miles. Now it's going to cost $2500 to get it replaced. This is absurd. I could have bought a Chevy Tahoe for half the price and never had this problem. I expected more from Mercedes than this. Sadly enough, I was looking at an e350 for my self.....not any more. Lexus here I come....
This car been brought to the dealership many times to fix this issues but still has not been resolved. Very frustrated. Engine light comes on cus the chamshaft sensor,tail light comes on, passenger air bag enables,transmission shift jerky
same exact problem, I hope they recall all the cars or extended warranty for this problen that affect the engine, I called the manufacture and I was told that if we all take it to a certified dealer and all the problem match are a like have the dealer or called back the manufacture and they will open a case to investigate in order to post a recall why dont we get that started? if you alreday called the manufacture and reported it please share your exact error code so we can all use the same to report it to the master ticket
Check engine lights comes on (usually during highway driving). Somtimes while sitting at light or if stopped it feels like engine is shaking
The check engine light just appeared and now I have the same problem. I called Customer Service at and basically it's too bad so sad. They do not seem to think that there is a problem. Obviously there still is a problem. I was told that MB manufactors this part.
i brought my 2006 R360 to the shop for a regular service to be told that the cam shaft intake and exhaust were worn and required an extremely expensive fix. Merc. Benz reference is p0017 p0016. Is there a class action law suite on this matter, from research it seems to be a frequent problem. Gerry
Same problem. The CEL came on and went directly to to the dealer service center. The replaced the intake manifold first. As I ws driving away the CEL came on 2 miles from the dealer. Turned around and left the R350 2006 and 2 day later got THE call. We need to replace the balance shaft and they need to take the engine out of the car. 10 day repair. Thankfully I purchsed the extended warentee. The total cost for the repair approx. $6,500-$7,000 USD. Ouch. Karl Benz is rolling over in his grave....
Check engine light kept coming on and Mbz of Wanut creeck diagnosed it to be faulty balance shaft. Estmated cost to fix the problem: over 8,200 dollars.
Check engine light. Mercedes said it was the balance shaft. Fixed the balance shaft and still had the light and now it's the cam gear adjusters. Always have had regular oil changes. Spent $4000 on balance shaft and now being told $3600 for cam adjusters.
Had MB replace the 4 wires/magnets under the open service issue but said the problem is with the timing belt etc. Now paying 3500 to have the entire thing fixed. Unreal....
Same engine light issue. Dealership states adamantly that this is not covered under any "campaign". Cost to repair all four magnets is $568.00.
Same problem here, I have a GL450. Engine light on requested me to replace two camshafter sensors. I replaced. the light is still on after I restart the car. MB must recall the car.
Same issue here ... Check Engine light on, diagnostic showed cam shaft position sensor needs to be replace. MErcedes Benz (MB) dealership said repair would cost $550.00 and another independent auto shop gave a price quote of $800.00 (basically $200 for parts, $600 for labor). If this is a consistent problem, let's notify MB as a group and fight for a recall. It angers me that repair shops can put any price tag on the same issue from $500 - $3k that should have been the manufacturer's responsibility.
Had Camshaft issue fixed in 2015 for free due to the recall item. Check engine light came on recently. Mechanic showed me printout for Camshaft and noted that it looked like it had been repaired before and that dealership should fix again. Brought to dealer. Dealer told me not a warranty issue and quoted $7600 to fix Camshaft adjusters. Also recommend timing chain replacement for $1000 (think I had this repaired less than 18 months ago) and oil centrifuge replacement for $292. I really do not trust dealerships and "service advisors" that add NO value to the process. Prefer to deal with mechanics who rely on their performance to keep your business.
