Mercedes ECU 

Up for sale is a Working, in excellent condition Mercedes E-Gas module. VDO Part number-- 412.225/001/012  /  412225001012 , mercedes part number-- 124 545 06 32 (1245450632). This ECU came out of a 94 w124 chassis Mercedes E420. May fit other models/years, but as always your best bet is to match the part number to the one on your ECU. This unit controls the electronic throttle housing in these cars, and can cause all sorts of problems, things related to cruise control, idle control, ASR and throttle control issues are all fair game.  Frequently these control units can be damaged by wiring harness problems, so be sure your throttle wiring is in good shape! These units now have to be special ordered from most dealers new for big $$ (often times several thousand bucks!), and finding a good one second hand is getting to be a very hard chore.
