Hi. I have the same problem that everyone seems to have - airbag warning lights, fuel cut off unavailable and start stop unavailable.
typecastboy - The link to the eBay guy is broken - do you have an up to date one?
Thanks for your help…
 
Yes, sorry, I forgot he relocated to Romania and has changed his ebay name. Here's a link.

I woudn't use anyone else, I've had issues with others bricing my ECUs, they always work when using this guy.

This is a crash data wiping service though, I'm not sure whether he actually repairs them. Drop him a message with what's wrong, I'm sure he'll be able to advise you.

Awesome. Thanks for your reply. And it still a case of buying one second hand and using him to wipe any crash data?

Does any one here have one for sale..?

Just a thought, but IIRC LHD & RHD cars use the same hardware but different firmware - there was a DVLA recall around 2010 for the early cars, as there were cases of the incorrect side airbags inflating in certain types of collision. The recall involved reprogramming the ECU firmware with a later version developed specifically for RHD markets.

If going this route, and particularly if using a service outside of the UK, I'd be asking some searching questions to ensure that the ECU firmware was reflashed with the correct version for the car concerned.

Just because a reflashed ECU installs with no apparent faults, and no warning lights or error codes, doesn't necessarily mean the airbags are going to deploy correctly in the event of a collision.

I've a lot of sympathy for folks facing this issue; best practice says that repairs should only be done by either a franchised dealer or an accredited airbag specialist using brand new components, but the cost of following this practice would likely make the repair uneconomic on an older 500. The code of practice says that SRS parts recovered from salvaged or scrapped vehicles should always be destroyed and never reused, yet eBay is littered with listings for such parts. It's a hard choice for someone with an older car on a limited budget; but how do you put a price on safety, particularly for an event which is extremely unlikely, but could have disastrous consequences if it were to happen?

For info, part number 51782985 is an early software version of 51867767 so either can be fitted. I currently have 51782985 fitted to a 2008 500 and when contacting Fiat for a replacement they quoted me for the 51867767 version. There is also an interim software version 51848079 which should also be a suitable replacement.
(These are all metal cases.)

Be aware that there was a DVLA recall for the airbag system on the early cars; IIRC the fix involves reflashing the firmware, so I'm not entirely surprised to hear that Fiat also updated the part numbers for the airbag ECU.

If the airbag ECU firmware isn't the correct version for the car it's fitted to, the airbags may not deploy correctly in the event of a collision. In the worst case scenario, this could be be the difference between life and death for the vehicle occupants.

Given that some, but not all, of the early ECU's will have been reflashed as part of the recall, there's absolutely no way of correlating part numbers with software version on a secondhand unit.

So far as I'm aware, MES can't reflash the airbag ECU, nor is there any readily available version information or reflashing software in the public domain.

Putting the airbag warning light out is easy compared to establishing with certainty that the correct airbags will fire with the correct timings and sequencing in he event of a crash.

There are sound reasons why the code of practice states that salvaged SRS components, including airbag ECU's, should never be reused.

For follow up, having the same symptoms as this thread (airbag warning lights/fuel cutoff) the problem was diagnosed by an auto electrician as being a faulty airbag module. I made the decision to go down the new route and fortunately found a new one being sold by a motorhome dealer for £400 instead £525+vat quoted by the Fiat dealer. The part has been fitted and after a proxi alignment the warning lights are now gone.

FYI Using Multiecuscan, if you can access the airbag module you are able to see the software version. For the latest airbag module part no. 51867767 the software version is 6592875106 Ver: 1814.
