0 265 100 051   ECU Up for sale is a Working, in excellent condition BOSCH ABS Control Unit.  your best bet is to match the part numbers with the part you need. These units now have to be special ordered from most dealers new for big $$ (often times over $1800!), and finding a good one second hand is getting to be a very hard chore. While these are fairly reliable units they can be damaged by voltage spikes caused by a bad alternator or random EM interference. At this price buy it and throw it on the shelf if you plan to drive one of these fine cars for a while. I only sell the OEM units, never aftermarket so they are the same quality as your original. Thanks for looking!
