Mein Auto: -98 Mroadster S50 Estoril
z3 airbag + p1622

Hi
recently bought a 2.8 -98 roadster. Some kind of mid-life crisis or maybe maturity - to give myself a treat. And a treat it is. Lovely car both to drive and to look on.

On my way from Oslo, Norway to my hometown Uppsala in Sweden the airbag warning light went on as i started in the morning. This I understand is nothing unusual and after having read a few threads here and in other forums I got prepared to remove the seats and check the connections to the airbagsensor and the belt tensioners.

But I thought I'd better check the DCT code first. When I hooked on the reader it told me P1622. But hey, that have nothing to do with the airbags that is "Map Cooling Thermostat Control Circuit Electrical". After having read a couple of threads on that I have decided to check those connections also before I get into changing the thermostat and stuff.

Now, my questions are: Shouldn't the arbag warning give a DCT code?
and shouldn't the eventual MAP coolant-thing induce a motor warning light?

and: you guys out there with more experience - am I heading the right way with this?

Per

not sure if this will help...

....the obdII Codes and the airbag codes are separate and distinct, with each requiring different dedicated readers...I use the Peake units..so if you're looking for the engine codes , you may not "see" the SRS system items related to the warning light..but for sure some SRS codes will be lit up, or the warning light would not be lit...Hope this helps..Z3 Cheers! dk '97 2.8 bg R, +1("Z-KANE")

Ok thx. Then I will have to look for another device. I will have to reset the warning light after checking the airbag sensors anyway. A bit of internet exercise again...

And then I'll have to find out why I get the OBD code.

But, this was one of the reasons to by an old, stunningly beautiful car - to treat it well!
