my car is Audi a6 avant , 2004, 3.0 quadro. millage 11000-13000 (don't remember exactly)

yesterday all gears on display has lighted up at same time ( i mean RDNS..) , i have changed transmittion fuel and filter one month(or less) ago and it worked fine after it

it seems to working on tiptronic (not on automatic) , but the lights are still up ..
someone told it should be transmittion computer (or what it is called) problem

so somebody can tell me what the hell is wrong with him and what to do?


sorry for my bad inglish

 

When the PRNDS is lite, it means the transmission or the computer (TCM) is done for.

Before you do anything expensive,Check the passenger side bottom carpet. Remove the carpet and he TCM will be located below the carpet. Examine te wiring and check if the computer is wet. Most of the time the computer is gets wet due to the clogged drain holes.

Hopefully the mechanic changed the fluid correctly. The temp must be monitored to accurately fill the pan with enough fluid. If the temp is not right the fluid will be under or over filled.

 

just came from specialist , he said it is probable computer of transmission (which is inside of him)

 

moders please close this thread.

i changed only transmission computer (~170$) and it works perfectly.
