9103 The resistance value in the ignition circuit containing component R12/6 (Left rear ETR ignition squib is too high) Hi guys been reading on this topic abit since I have had the same srs restraint system defective message come up. Has anyone eles had any problems with this? I believe it's a fault caused by the wiring harness being too short. I am under the impression this was a manufacturer fault. Did MB admit to this in the UK as they did in the US?
