Airbag Ecu

[teresam]

I am trying to find a replacement for the airbag ECU, the one I have is made by Temic and has the following numbers on it:

9641968380
MRSC/G31/10
A9
L3T1G16A8WO
+5EKABY218099H

Looking at ones for sale I can match the first 2 numbers but not the others. I have tried googling for information and looked for a Temic website without success. Does anybody know what they all mean, or which ones are important?

The Citroen part number for the ecu is 6546E6 for one that needs configuring or 8216AS for one configured for your car using your VIN. So you will need a replacement ecu to be configured to your car which will need a diagnostic, probably at a dealer. This is to tell the ecu what air bags are fitted and pretensioners and to check that none of them have any faults. If from a car withthe same air bags, etc as yours, it might just be possible to fit a used one and it might be ok but without the diagnostic you will not know if it has been programmed so all your air bags/pretensioners work.

 

A search on 'C5 air bag ecu' comes up with a few used ones such as this which appears to have the same part no of 9641968380 https://www.ebay.co.uk/p/?iid=162481166978&&&adgroupid=33676502101&rlsatarget=pla-270397344923&abcId=893836&adtype=pla&merchantid=7320304&poi=&googleloc=9047021&device=c&campaignid=707291931&crdt=0&chn=ps

Thanks Paul.  I am trying to find a used one, mainly because I can't get one from citroen UK and they would have to order it from France which could take weeks (which I can't afford wait) so providing I get one that has the number 9641968380 can it be programmed to work in my car?

I am not sure but I would think a used one can be programmed to your car. Since a used one does not cost much I think it worth just trying one without the diagnostic until later on.

 

Forgot to ask before, why do you need a new ecu ?

Thanks Paul.
