I took my car to the audi dealer and they told me my car needs a new tcm. Its gonna cost about 2500 to replace. Any other alternatives to this or anyone know a good place that I could buy one for a better price. Thanks. BTW its a 3.0 fwd.

 

I used one of those 'Spare Parts' online forms that you fill in, and various Wrecker/Breakers yards contact you with used replacements. Mine was the slightly older 2.8 version tho, in the end when i cracked it open it was some corrosion on a few of the pins.

I just replaced the pins and was good to go. If you don't mind a used one they may only run you about $400-$600, it's easy to replace, but you have to get the whole carpet up on the passenger side.

 

There is a class action lawsuit possibly relating to your issue. If the TCU was damaged by moisture from clogged drain, then you may be off the hook for the cost. Do a search.

 

I have a TCU with VAST chip tuning, I swapped to a MT so I dont need it anymore, shoot me an offer, roughly 10% of what Audi told you

 

You can also try typing in the main part number into a search on ebay I have rebuilt two A6's with water damage and have found controllers for both on there just got one two weeks ago for $175 just be sure the part numbers match exactly.

 

Would this work on my 02 a6 3.0 fwd? Also what does the chip do?

 

Where exactly is the tcu located in the car?

 

We can help you out.

 

How much can you get a good used tcm for?

 

It will not fit a 3.0 FWD
