54 C3 Sensodrive ECU Serial Numbers

Post by davedougan »

Hi the Sensodrive ECU has gone in my partner's car and I need another. The dealer wants £350 which is way too much. I can find them on Ebay but the letter after the "S" serial number is different. Mine is S118475201 E but the one on Ebay is a C instead of E . the small SW serial number is also different but the HW one is the same but I suspect the important numer is the large print "S" code. Does anyone know if the ECUs are interchangeable with different suffixes.
Thanks David

I can't say for sure, but it is a good likelihood that the eBay C is an older revision of the unit( yours being a later unit) the SW will likely be the software version supplied with that version of the hardware. If you send me a PM with your VIN number I'll look at the ECU and see what the part number is. The only issue I would say is if you put in an older unit than you have already. This is because they often make changes to remedy known issues. I personally would only put in an equivalent unit unless it has been superseded and this would also depend on your build number. Like I said I'll have a look for you to see what the docs say if you get me your VIN.

Can't be 100%sure, but the main difference is ABS breaking or not.

David - sent you a PM, but not sure if it has gone - not showing in sent box for some reason. Your VIN is a character short - can you check and I'll take a look this morning?

Dave - found the missing character. Can't see anything specific on replacement Gearbox ECU concerning the ECU types, but did note they say to make a note of the gearbox info with your lexia prior to removing the ECU as you'll need it to re-programme in the replacement. You probably know that anyway :-D

Hi Thanks Marc....I didn't know that so thanks. I'm still getting the hang of Lexia. It says the ECU is faulty so I'm not sure which info I can get from it. Any chance you could point me in the direction of how to access it via Lexia. I've a 2nd hand ECU coming on Wednesday and want the car up and running aso soon as possible. Thanks again for the help.

No worries - it doesn't say what info just 'info', so hard to say. At the moment I'm waiting for a new laptop battery to be delivered as the current one isn't holding charge, plus it's peeing it down, so I cant use the electrics! As soon as it arrives or the rain stops I'll hook up to the C3 (non-sensodrive mind) and see where and what info is displayed on the ECUs. May be something as simple as a code number. I can understand that if there is no communication with the ECU in question then it would be difficult to get the data. It may be accessible from the BSI - but I'll let you know.

Bad news.....replacement ECU arrived...which I was assured my NCS car spares came from a working vehicle. Result was....No change :(
Lexia is saying the same as before "Gearbox ECU Defective - Replace ECU" . The only thing I can think of now is that there's a break in the CAN BUS wire between the BSI and the ECU which makes the BSI think it's faulty when it's not. (There appears to be power getting to the GB ECU as I've multimetered it and I'm getting 12v)
Does anyone know if there's a test you can do to find if a signal is getting as far as the Gearbox ECU connector as this would save me having to trace back each wire. Also....anyone have a wiring diagram - the car is for the scrappers unless I can fix this, there's no time pressures any more as I bought another car but this is really too good a wee car to scrap so I'm determined to get to the bottom of it.
