VW MOTRONIC ECU 03G 906 016AB     /     0 281 012 238    /    016-AB

Up for sale is a Working, in excellent condition Vw Golf/Jetta TDI ECU.  The unit was removed from a crash damaged 2006 Jetta TDI that still ran.  It most likely fits many others- please compare this part number with your original to confirm fitment.  This unit needs to be programmed before it will work in your car.

as always your best bet is to match the part number off your original unit with this one. 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 are also great for tuning purposes, if you wish to keep a standard original unit.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. This is located in the cowell of your VW - Where the wipers sprout out from. Unit comes with a 30 day warranty, replacement or refund if returned in original condition.
