I am looking to buy a used airbag control unit and there are three part numbers available for a 400E. I have a 1992 400E and am looking to get one from a 1993 400E.

The numbers listed on EPC net (Startek Info) are:

A 000 820 68 26
A 000 820 69 26 and
A 000 820 72 26

Are the control units interchangable or do I have to get exact same one currently in my car.

Thanks,

HS
