touch terminals together is easy. remove both terminals possitive and negitive and hold them together for a few. i always used zip ties..

key on key off. remove negitive cable from battery. reconnect turn key to on poss. wait 2-3 minutes (you will hear tb buzzing with your hood up) try to start. if start is not achieved. key off, key on push gas pedal to floor hold for 30 sec release gas pedal start car.

i cannot say they work. t
mind you at current moment i need throttle body aligned. This is 3rd time its happend. first start up on g2 it happened again due to a bad cell in battery.

First time i got car into limp mode with one of these tricks not sure which one.
Second time i had to trailer car.
Im going to replacd the throttle body i think. I have heard if it happens to many times you will ruin tb. Not sure if its true but would give myself peice of mind. Also with a new tb how would it align. I would still be in same boat?

Isn't there a TB sensor? Maybe it's bad and has no idea where your TB is... I might not even realize there is even a TB under the hood... Maybe the sensor thinks the TB is in the trunk or something?

.....Throttle Body Alignment
Updated 29 Jan. 2007

Ross-Tech is not responsible for any damage or problems that may result from following these instructions. They are to be used at your own risk. As always, you should refer to a Factory Repair Manual for your vehicle!

This procedure details how to perform a Throttle Body Alignment (TBA) on many VW/Audi vehicles. This procedure cycles the motorized throttle body through various states (idle, part throttle, WOT) to relearn their positions. Some examples of reasons to perform a TBA:

*

The vehicle's battery has been disconnected and re-connected
*

The ECU has been removed and reinstalled
*

The Throttle Body has been cleaned or removed and reinstalled
*

The Accelerator Pedal has been removed and reinstalled

In some vehicles, the car will not run correctly, or may not run at all without performing a TBA after one of the above operations. The TBA can be performed on both Drive-By-Wire (DBW or E-gas) as well as Cable-throttle cars as long as there is no Idle Stabilization Valve (ISV). If there is an ISV, then there is no motorized control of the throttle at all. Typically, '96-'99 VW/Audi have motorized Cable-throttle, and '00+ VW/Audi have DBW. Obviously, there are some exceptions. This should be obvious but TDI's do not have throttle bodies.

You would be in the same boat of needing alignment but if that sensor is bad and doesnt know its right from left them your car is saying TB go left and that sensor is sending it right.

limp mode is a factorty defualt where car will run but not well. most of time when there is an issue with a major component or it actually did fail, car will go into limp mode.
as far as i know it is to prevent further damage.
