VW part number 037906022BE / 037 906 022 BE , 0261200590 / 0 261 200 590 . This is a factory BOSCH replacement unit, which was used to replace a defective triumph-adler ECU at some point in the cars life that this came out of. This BOSCH unit is generally considered by dubbers to be a nice improvement over the original equipment Triumph-Adler units - which can sometimes be problematic. came out of a 92 VW Fox, should fit other years/models, However as always your best bet is to match the part numbers with the part you need. 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.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.
