I love this car! Bought it 14 months ago from a dealer. Got horrid gas mileage (15MPG) and they said nothing wrong with it so I sucked it up. Ran great until I took it to an independent German shop for a brake job and when they went to start it the battery was dead so they replaced it. Since I got it back there was a fresh diesel smell that lingered long after being turned off and I could even smell it in the garage in the AM. It also started really rough, and idled rough until it warmed up. I took it back to the shop and they replaced all the fuel lines, hoses, actuator, etc., and $1800. later I no longer have the smells but it runs rough, smokes and NOW the BAS/ACR light comes on. The shop says their computer won't even read it now. Does anybody have any ideas? I am very frustrated becasue I love this car!
