028 906 021BD BOSCH Engine Control Unit 0 281 001 438    021-BD 

Up for sale is a Working, in excellent condition VW Diesel TDI ECU.  This is from a recent crash damaged 1997 model with the AHU code TDI engine -
66 kilowatts (90 PS; 89 bhp) @ 4,000 rpm; 202 newton metres (149 lbf·ft) @ 1,900 rpm — 1Z, AHU
 Correct Part numbers listed at top.  This unit comes with a 60 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 as well as emission control & cold or hot start problems.  An erroneous check engine light is especially problematic, as the car will not pass the emissions portion of the test at the annual state inspection.

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.  

Please note, that misdiagnosis of a good working ECU is one of the primary reasons we get these units returned.  We no longer accept returns on these units without a 30% restocking fee.  We test all units we possibly can, and will test any returned units.  All units we sell are operational units that came out of crash damaged salvage cars.  Unlike most sellers on ebay, we never sell ECU's from no-start cars or from flood damaged cars!
