Hello all, i have a Eclass merc estate that i have a slight problem with. While driving along bas light came on and lost a little power, pulled over switched off then it wouldn't restart. Had it recovered home and checked it over to find it had blown 10A fuse F3 in ecu box. Traced wiring back and found that 2 wires (red an brown) twisted together were causing problem. leave disconected and fuse stays intack but bas lights stay on and im unable comunicate with scanner to bas unit. Thinking power issue still. These 2 wires go to a fan in ecu box. Fan isn't seized and all wires going to it are ok.
Anyone with same problem. I'm thinking fan but why would that interfere with bas unit
