Technical Airbag ECU replacement (2 of Henks were faulty so far) need help please

[MarlaS]

Hi
I have a 1996 Barchetta. The airbag ECU died and I am having a hard time getting parts (apparently Henk has passed away? And the parts sent do not work for my mechanic). From my mechanic:

One of the modules gives me the fault code 201 "airbag module fault" and the second module which I have just tested is not communicating at all with the diagnostics computer. I have reverted back to the first module to ensure that I do not simply have a blown fuse or other issue that would explain not being able to communicate with the second module received but this is not the case, ie I can go back and communicate normally with the 1st module.

For your information I am able to provoke new faults (disconnect a pretensioner or airbag charge) and then clear those faults but the fault 201 is permanent and will not clear.

Many thanks for any assistance you can provide.

Also - I will search the forum but is there another place to buy these? I probably can get them on ebay.

See attached with Serial Numbers etc.

It is known that airbag module number 46443798 has a bug. You can reset fault codes only some 5 times, after that ECU will be locked. You can't clear the codes without reprogramming whole unit.

I had same problem on my 1996 B, and to solve it i bought ECU with spare part number 46476309. It is drop in replacement and does not have same problem. So you can reset codes as many times as needed.

46535343 as fitted to the later CF3 'B's should work.
