Had this Merc in yesterday with SRS light on. Fault in the system using KTS was B1035 Sidebag ignition
circuit, driver side High resistance.

All sorted with a clean up of the connections under the seat on the passenger side.

Is this a problem ? I've seen this before on Renaults but I was thinking about it last night and wondered if there may be a problem with variant coding . Is it possible the wrong airbag could trigger ?
