The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

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....
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..

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
The check engine light just appeared and now I have the same problem. I called Customer Service at MBUSA.com 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.
check engine "on" code P0025 .start and running ok.
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
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....
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.
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.
Cam shaft warning lights. Needs replacement. Quote was $6,500
Same engine light issue. Dealership states adamantly that this is not covered under any "campaign". Cost to repair all four magnets is $568.00.
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.
Check engine light on due to camshaft adjuster
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....
my o2 sensors keep giving me codes p2240
I had a check engine light on. Went to MB dealer and was told it would be $2500 to replace the timing chain. The service advisor told me not to spend the money because the Road class is the worst car MBA ever made. Disappointing.
Same problem as described The benz mechanic tried to rebalance with magnets light still on but car works correctly!
