Hi,

After a lot of research, im getting mixed opinions.

I have a mk7 Golf which was crashed with airbags deployed, these have all been replaced but I still have the light on due to the crash data on the ECU.

Do airbag ECU's need to be replaced with brand new ones when airbags are deployed or can crash data be wiped and it be re-used.

Some people say the ECU have a form of loaded gun sensor that can not be re-cocked others say thats not correct.

Im happy to pay for my safety but its the difference between resetting the ecu for £45 or a new one from the dealer for £440.

Thanks

Manufacturer specifications prohibit resets, in fact they are illegal in the EU as far as I am aware. No serious company that offers control module repairs actually offers those resets. So much for the legal part. The circumstances after which an airbag control module must and must not be replaced are explicitly outlined in the factory repair manuals (i.e. what kind of crash was it? Front, Side, Rear, Rollover?). Just general crash data should not result in a warning lamp, so there must be more and pending an Auto-Scan we should be able to find out what the problem is.

Please post us an autoscan if your car so we can see exactly what your car is saying, as the light may not be due to only the airbag module.

In answering your question, yes you can get it flashed. But to re-iterate we need a scan to see what's actually going on.

Thanks for the replies. I have attached an autoscan, I believe the fault code is because there is currently a non crashed used ECU fitted which the car has not accepted, I since found out a used ECU cannot be re-coded.

Code:

It would appear that component protection is active. This can be removed by a dealer or someone with access to ODIS.

You need to also post a full scan with the headers.

It would appear that component protection is active. This can be removed by a dealer or someone with access to ODIS.

You need to also post a full scan with the headers.

Would this just be due to the non compatible ECU currently fitted though? and fitting a brand new ecu in will clear this?

No. The airbag ecu is part of the constellation that the car checks on each startup. Even if you fitted a new one it would still need to be programmed

Got you, cheers. I think I will just get a new one and get it coded to the car. ~£500 is a small price to pay to know my airbag ecu will do the job if the worse were to happen.
