Error codes
Title: Reply to Spinnetti

Hello Spinnetti. I would first talk to an Audi technician before spending $$$ on parts... Several things not working could have one underlying cause. Mine was that fuse, which DOES NOT control the fuel pump. Wiring diagram from eBahn will help in a case like this. Instead of replacing MAF, clean it. Then unplug it. If RPM does not change, then it is either dead, or there is a fuse or wiring problem. Throttle body -- clean it first, then clear VAG error code, and only then replace. And always, it is better to find a replacement part from a friend or scrap yard, and try replacing it first.

Comment: So at first, I checked all the fuses and none were blown... then I looked up the fuse map in the manual, and fuse 29 (bottom of the second row) was completely missing... Put one in, and bingo, life is good. I had taken it to a shop, and I suspect they were trying to hose me by removing the fuse and saying all those components needed to be replaced.. Not sure if they were crooks or just incompetent... Regardless, I'm happy it runs good now.. Thanks for the find - this info wasn't on any of the Audi forums...

Comment: I got all those EXACT same codes (upper part of the page)... I replaced the MAF, and the code didn't go away. I clean the throttle body, and then it failed adaptation and had to get a new one ($$$)... now it runs worse than ever, still has the same codes and the MAF still shows bad - going to check that fuse now, but don't understand how that could have any bearing - if the fuse was blown, there'd be no fuel pump right? Did you just change the fuse as indicated, or change the relay?
