Back from the Chrysler dealer and 50+ euro lighter without any progress whatsoever.

Although I had an appointment, I had to wait for an hour for them to get the computer from another location. After 10 minutes of work they gave me the same message I already knew and had e-mailed them. Fault codes read belt tensioners andwill return after reset. This in the car for which we know there is no fault whatsoever.

Since I've heard this say from separate sources, I am now going to change the airbag modules back to their respective original car. It could be they're 'married to that specific car. See what happens then.

BTW, the mecanic tipped me I could shorten the circuit with a 2 Ohm resistance (or alike) to stop the light from coming on and keep the airbags working.

BTW II, that Chrysler stealership is Kien in Arnhem
