tr Mercedes ABS ECU Up for sale is a Working, in excellent condition Mercedes ABS Control Unit. Bosch part # 0 265 101 018 , MB part # 005 545 21 32. This ECU came out of a w124 300d, however it should fit all w124's with ABS, Many W126's as well as W201's with ABS, it may even fit other models/years. However as always 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 $1000!), and finding a good one second hand is getting to be a very hard chore. These are generally quite reliable and usually only problematic if they become water damaged or the car suffered from other electrical faults (such as a bad alternator or rodent damaged wiring ). 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!
