Audi ECU Up for sale is a Working, in excellent condition Audi A4 A6 v6 ECU 5DA 007 193-02  4A0 907 473 D  May also fit 80 B4 100 C4 - you must check your original part number to verify fitment.

made by Hella, the original manufacturer. My list shows this is original to many 1996-1997 A4 & A6 models with the 2.6 Liter engine, including cabriolet (convertible) - only NON US models.  We got this control unit on a recent trip to Sweden, so this should fit MANY euro specification cars.  Unit removed from a recent crash damaged car, and comes with a 30 day warranty.

As always with this type of component your best bet is to match the part number to the one on your original ECU. A faulty ECU is one of the most common no start or random stalling problems with these cars. These can also cause issues with erroneous check engine lights, idle control problems as well as emission control & cold or hot start problems. I have also seen fuel pump relay turn on faults (ECU won't turn on the fuel pump), as well as an condition where the high speed injector driver has failed. This causes the car to sit and idle fine, but it won't accelerate. These units are also commonly water damaged cue to their positioning in some of these cars.If your car does not have these issues but you intend to keep it a while, I recommend our customers keep an extra ECU in the trunk. These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and you can never find one when you need one. Even now finding a good one second hand is getting to be quite difficult as these cars get older. If you have priced one of these new, you probably were quite shocked at the price.
