Not for nothing. But I swore by these guys at 1st. But now fortunately, I'm swearing AT them! Numerous and I mean numerous trips to diagnose and repair a service engine light on my 2001 325XI. Several thousand dollars later. My engine light has come on yet again. From an O2 sensor to 2 vacuum lines to an air solenoid which led to an air pump and valve job. In the interim they did a fuel pump and the day after an idler pulley and belt tensioner went. Now I'm not superstitious however I had pep boys do that job just to be on the safe side. Talk about frustration. Seems every time they work on the vehicle 2 mores things go wrong. Proceed with caution is all the advice I have to give....
