ECU + Wiring Harness replaced
The wiring harness and the ECU (Engine Computer Unit) have been changed and after one month w/o car (Parts ordering and replacing and testing) everything seems well working now. (About 2100 Dollars)
But I have done a deep ckecking around the physical implementation of the ECU and there is no trace and stains of acid of the battery, in this area and nowhere. It seem that the wiring harness was damaged by crushing and squeezing and NOT BY ACID. I guess that Mercedes tells that because they will not accept to be responsible of a bad setting of these cables.
What is your position ? Thanks
