Old guy - should I trust the parts department of my local Audi dealership on identifying parts needed off my VIN (not that I'm actually gonna buy from them if it's a lot more)? Assume with my VIN they would be right, but sure seems more like a VSS and/or magnetized wheel/gear problem (especially with no ABS or other dash lights originally).

I will be looking in there to clean contacts and can look to identify sensor then hopefully.

To update on status (because this seems wierd): Last night when I went out for errands the speedo needle was a 0 and didn't move for about 5-10 minutes. Then it started to move a little bit and around 10 minutes plus of driving the speedometer was working, but not extremely well. It was like it had to warm up to work, which did occur briefy yesterday as well. Then this morning when heading to work the speedometer worked, but not well. It does show acceleration, but does so slowly and does not adjust quickly. When the speedometer is not working the odometer is not (the trip odometer reset itself as well, if that helps), but the odometer works somewhat when speedometer is working (badly). A check engine light did just come on, but I haven't had a chance yet to run it. I have been having CEL issues with the second O2 sensor since my K04 and APR K04 software upgrade, so the CEL may not be anything with this.

Doesn't seem like a cluster or abs problem. I'm gonna get into the passenger front wheel well and make sure nothing was broke there where the curb was hit, but I don't see how something on that side could affect the speedo. Sure seems like a Vehicle Speed Sensor (VSS) and/or magnetized wheel/gear diff problem.

Here's the post I started on this problem specifically: http://www.audizine.com/forum/showth...1#post10368807
