I've had my car for several years now and it has been a trooper, currently has about 140,000 on it and the problems are really starting to add up unfortunately. The biggest problem right now is the surging at light throttle and even idle. I've read and read and read topics about this issue and have already done all the easy fixes, plugs, air filter, fuel filter, cleaned winter screen. The problem is still there, now before someone jumps on the it's your torque converter bandwagon explain how that can be when it does it in park with no load on the converter? I want to pull the throttle body and clean it but wasn't sure if you have to recalibrate it with the VAGCOM which I do not have. Do I have to recalibrate it or not?

Other issues piling up.
1. Navigation appears to be lost, not showing me as where I am or even close.
2. Parking sensors have stopped completely
3. And even though it hasn't happened recently, I've had issues with the battery discharging for no reason.

Any help is greatly appreciated.

before we start guessing, post a complete VCDS log.

Based upon what you've written it could be as simple as a low battery or something with the BT module or ???

BTW, you will need a VCDS to do throttle body alignment: Throttle Body Alignment (TBA) - Ross-Tech Wiki

Like I said I don't have a vagcom, that's what I was wanting to know is if I can do this without. Sounds like a no.

Without a VAGCOM, you are asking us to use the Magic 8 Ball.

I also have a 2005 3.2 and the parking buzzer stopped working a few months ago. Another one taken from another 2005 3.2 did not work either. One taken from a 2008 model worked. I assume the buzzer on all 2005 models must be dead by now. So you may consider replacing yours.

This could help. Check the previous pages as well: https://www.audiworld.com/forums/a6-...2825207/page3/

Thanks for the info, I'll check that out. I did get the surging issue to stop by cleaning the throttle body, had to do it on the car but it wasn't that bad.
