Hey everyone,

I have a 2007 Audi Q7 4.2 S-Line... Just bought it with engine light on, and worked that out with a MAF replacement. Engine appears to be perfect again. I am however, running into issues, directly after replacement of the MAF, with shifting problems. Is this just strange coincidence? Or can that be linked?

After MAF R&R and clearing codes, I drove it about 6 miles to run 3 errands- shut it off 3 different times. Each time I drove it, the issue got worse and worse to the point of not being sure if it was going to go into gear when 3 point turning it back into my garage.

The problem: It was downshifting into 1st & 2nd VERY abruptly, to the point of your voice jumping while talking. When it would shift into 2nd & even 3rd occasionally, it would also thump pretty hard into gear. By the time I got it home, it would delay shifting from D to R about 5 second, and drop into gear very hard... Kinda like when you park an automatic on a hill without the parking break, then try to drop it in gear. "THUMP". I haven't touched it since.

The kicker, is I just bought this car AS-IS and am screwed. It showed NO behaviors like this, until today. I just drove it home Thursday night and it sat until this morning.

Thoughts??

Update: Pulled fault codes with a neighbor's VagCom. I have a total disaster on my hands here. 13 different fault codes, all appear VERY severe. It seems so bad, that it makes me wonder if it is centralized to an ECM or major electrical monitoring component. It's pretty bad!
