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?

The ETR is the tensioning retractor.

Looks like you have a fault in the left rear seat belt. Nothing to do with the drivers air bag.
 
I also have the esp message popping up. This with the above seemed like it was the issue with the harness.

And today I adjusted the steering wheel and since I have no steering function ie the horn, and buttons stopped working.

Error 9103 from my understanding is as a result of the harness being stretched to the point it's damaged?
