    Do 2008's have the revised cam shafts?

    Guest-only advertisement. Register or Log In now!
    I have 8500 mile on the odo and I recently had a check engine light that was diagnosed as a faulty fuel pressure sensor. I don't think the cam was checked for premature lobe wear. Do 2008's have the revised "B" cam from the factory? Should I take it back to the dealer and ask them to check the cam lobe?
    TIA

    yes. there is a tsb on it. they will likely replace the sensor and check the cam lobe. this may NOT ultimately fix your problem though....

    Thanks. I saw the TSB but that was published on June 21, 2007 before the 08's were out. So it would not include the them. I purchased my A4 in 10/07 so it is an early 08. I'm curious if I have the "A" or "B" cam. I already had the service done and there was no mention of checking the cam lobe and nothing on the invoice suggests they check it.

    My '08 started getting a CEL around 7,500 miles last month. I've been holding off brining it in to be looked at, but i'll keep this in mind. Keep us updated, and good luck!

    but when was your car BUILT? warranty service is free.... let them replace the fuel pressure sensor under warranty and keep your fingers crossed that it solves the problem.

    there's a link to the TSB... even though the TSB is supposed to be an internal bulletin that shouldn't be shown to us, print it out... show them that with your engine fault code they should check this. If they don't, complain to AoA.
