BMW E38 Airbag code 16

Error 16 => Driverís seat belt buckle switch
I tried to do a search about this code but results were very poor. For this reason I am writing a few tips, maybe there is somebody to find this helpful. For those that are out there and experiencing the BMW code 16 for the airbag: simple fix, that worked in my case, some contact cleaner and 2 minutes of my time. I took the seat belt buckle, sprayed contact cleaner until it was full, clicked the seat belt in and out as much as I could for about 2 minutes. I used about half spray can, reset the code with INPA and no Airbag light anymore. Apparently there is a circuit board inside that gets dirty or looses contact with time and clean it solved the problem. In worst case the seat buckle has to be changed, about $125. There is a TSB about this issue which I found available here:
Keep that bimmer on the road...

Dunno if you found the cn90 DIY on the seat belt buckle switch in your searches ... but the E39 link in red below should also apply to the E38 I think:

Thanks for adding value to this thread. I did nor run into the DIY when I did my search. And I usually start my search in the E39 section.I guess I need to dig more...:D
