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.

I have 2005 ML 350. Engine run and stop. sometime engine start easy and sometime does not start. Battery checked and engine crank ok. Any idea please help before i bring my car to the shop. Thanks
Camshaft sensors need to be replaced.I get all my schedule maintenance on my car this light have been on for about 4 years. At first he stay of now it is constantly on. I can not get My 2015 car smog with this problem. I call Mercedes dealer they said they can do a diagnostic test.that cost $145. They didn't tell me how much it would cost tho. I was told over 5500. This is a nightmare...l called another dealer who specializes in Mercedes he said it will cost 4500 to get it fixed. I cant afford this today. I have other pressing things on my plate. Im trying to take care of my Mom. How things are looking i may have to wait until January.

My vehicle is a 2006. I have had many mechanical problems and have spent thousands of dollars on repairs. I have heard that there were many lemons that year. I just picked it up today after having to replace the balance mechanism and the timing chain. I was told that mercedes would pick up 36% of the cost because it eas a warrenty issue....the cost of repairs was 3,200....labor being 2,100....I am angry and appalled....would never buy a mercedes again and if quality and cost is so high, why are they selling lemons....I previously drove a nissan for 150,000 miles with no major repairs.

Check engine light came on a week after completion of the schedule b service. Shop reports that the camshaft magnets need to be replaced. Quoted me $350 to replace the magnets.

not my car, driving my dad car for one day while his out of town, and i drive it as if his with me, nice and slow. At the stop light, In drive, on the breaks light goes green, i let go of brake and gas it nothing but rpms. i shift to n, cant get it to shift back into drive. i shut it off, turn it on, everything works fine. i go. later take to mechanic. checks the codes, says its 0633, some random code, no biggie, you can just reset. I said awesome, and we did a oil change. what the heck seems like it can use one. pick up the car later that day, leave, drive away happy, going to park this car and leave it alone. im driving.... i have to stop to make a turn.....RPM's// arghhh shut off car, turn it back on, check engine light on ! ahhhh mercedes, i was at a pivotal point in my judgement to switch from old school pre 2001 volvo's and was gonna buy me a new benz... but this, this just makes me sad. benzo you aint what i thought you were.
