had oil changed with Ammco in memphis Tn. They put the wrong oil in, then later changed it back. This left a rattle in engine.
does this car have adjustable valves on its engine? on 2006 Mercedes-Benz C230
I have had a similar problem. I had a cheaper quality filter made by lubrifiner and ended up with a rattling lifter or two. I am in the prosess to getting parts to change them. not nice, I was told by Mercedes to use good quality filter or this happens. There is no adjustment as they are hydrolic.
What kind of oil did they put in 'it shouldn't make a difference?
