Automatic transmission will not go in reverse. 153356 miles all other gears work fine. Audi 2001 A4 Quatro. Readout on dash reports "OK" when activated.

Sometimes when I lock with fob it locks but no beep sounds. Then when I unlock the passenger door won't unlock. Or all will unlock but driver side. It's very random. Sometimes it works sometimes it doesn't. What is the problem and can I fix it myself? Seems like an electrical issue or fuse ...... Please help

Car has 86,000 miles, unsure if tranny has ever been flushed or filled. Planning to flush, but had to order drain/fill plug tools from the outside world (Hawaii headaches).Periodically won't go into gear when in reverse, just revs, usually on cold starts in the morning. Recently gear selection box on the LCD started flashing when I put it in drive after it didn't want to engage in R. I noticed this at highway speed and put it into neutral, then back to drive. It wouldn't engage until I pulled over, put in park, then back to drive. Check engine light illuminated today. Question - Might dirty/low CVT tranny fluid cause this light to come on, or is it only associated with engine problems?

I never had my clutch go out on meat 28,xxx miles. I always had them last until 60,000 miles. From what I read the clutch is a major problem. The dealership is refusing to allow the warranty to cover it. So I have to paid over $4,000 usd to get it fixed. Is there anyone doing a class lawsuit over this or have done one?
