Replacing Airbag Controller

[kester]

there

 

after a small bump in my wifes alhambra (1999 110tdi) [same as a Galaxy] that set both airbags off, I am now trying to replace and reset all airbags etc.

 

I've found cheap replacement airbags, although need to obtain a replacement loom/connector before I can connect the steering wheel airbag. I've tried 2 replacement airbag controllers from scrap and cant get VAG-COM to read them. In fact when the controller is plugged in, VAG-COM refuses to talk to any modules in the car at all (e.g. ABS, engine etc)! Is this expected behaviour and is there something I need to do to the airbag controller before it will communicate?

 

Also in the process the fuel gauge now only reads empty with warning light on - but I've yet to investigate that (may be fault with sender, connector or instrument cluster I guess).

 

many thanks

As for Vagcom not reading any modules, are you sure it's configured correctly, have you used it OK previously?

thanks for reply :)

 

Yes, as soon as unplug the airbag ECU I can read all the usual modules. And of course I was able to read the old controller.

I think its my fault - i had not bolted the module down so it was not grounded! STUPID STUPID ME :ph34r:

I am now able to read the fault codes. Once I get the final cable/connector i'll be able to clear fault codes, test again and see if all is working

Glad to see you found the solution, and thank you for taking the time to let everyone know and lean from your "experience".

Hope everything goes smoothly from now.
