Thanks for the replies. I picked the car up today, and as MB DOC stated, the new fluid definitely helped. I still don't know the codes...the shop guys were gone when I got there and it wasn't on the paperwork when I paid. Makes me question whether they even checked for codes at Mercedes. I know the indy did, and I plan on checking with them tomorrow to see what the numbers were. I'll also call Mercedes and see if they did it. When I first started using Ross Motor Cars in Dayton about 10 years ago, the service was remarkable. I've been disappointed ever since the owner died and a fairly young daughter took over. Going to have to drive to Cincinnati or Columbus to find a new shop. MB DOC, ever thought about moving to Ohio? You'd get my business.
