    So my car has been fine for the past 2 weeks up until the other day it when I come to a stop it almost dies everytime until it warms up. When I switched it to tip-tronic it worked fine for a few shifts then wouldnt let me shift anymore I shut the car and started it again and it was fine after that.

    I did alittle research and im not sure but it might be a MAF?? seems I have a evap leak and the most of my worry is the ecu problems?? let me know what u guys think

    Thanks

    Try cleaning grounds first- all of them. My A4 had some intermittent issues with running/codes/readiness and cleaning the grounds solved it.

    This may be a stupid question but my grounds that run off my battery to the frame? Or is there more to look for?

    Thanks

    they are located in several areas throughout the car. I think the Bentley gives diagrams as to where they are located..

    There is a ground harness that runs to major engine components. Like the doctor said, check a Bentley or do a quick Google search for "b5 <engine> ground diy" or something like that for locations. It's pretty standard when trouble shooting 10+ year old vehicles.

    Along with what everyone else said, the first fault needs to be fixed before anything else. Terminal 30 is the main power bus for the whole vehicle. If the ECU thinks the voltage is low then anything is possisble. Check the battery connections/grounds and once that fault is resolved then see what happens. But till that is cleared you will have random issues.

    So I switched back to my 2.8 and for the first start it was not holding a charge to the battery so I pulled the battery out of the other car and it started up fine but sat at 12v on the dash. So I gave it some gas and it shot up to 14-16v and sits there now every time I start the car I have to give it some gas for it to jump to 14v if I don't it slowly drops but I havent let it go below 11v this would mean my alternator is going?

    Your alternator control module is on it's way out. (or the brushes are worn) There are several 2.8 v6's at M&M, they aren't too expensive even for a whole alternator- just a pain to remove/install.
