Do you have a number for the ECU at all ?

Right, sorry about the delay, here are the numbers from ECU sticker on the 2.5 V6 Auto, '98 MY:

From the top

980702        26SA4475
86702          1763 0078

0 261 203 588 followed by 810 in small writing

GM 90 492 382

B95001   86702 0076

They are all on a Bosch sticker having large letters HH in the bottom right hand corner.

Hope this helps and sorry for delay in reply.

Regards .......... Rob

Thanks - I`ll go and do a bit of research

Sorry, unable to turn off the immobiliser on that one

 

However, I can retrieve the Vehicle Pin Code (PUK) from the aerial around the ignition barrel though if that is of any help? But you would need to send it over to me, for me to read it.

If you have 1 transponder, selotape transponder to immobiliser aerial - saves having to progra more keys.



Dave, interested in how that works, implies the immobiliser transmits the through aerial?

If you have a look at that aerial, you will see a small surface mount chip - and amongst other info it contains, is also the vehicle PUK code.

The aerial recognises the transponder key, obviously, but is also paired to the ecu and various other parts of the car, which is why its difficult to change the aerial ring on its own, without the paired ecu. the ECU needs to receive the data from teh aerial with regard to the transponder as well as the pairing code from the aerial, and only then does it turn off the immobiliser.

Hope that confuses you further

That's very useful Dave - thanks for that.

It certainly gives me more options re operating the car that's for sure.

How long would you expect to take to access the code - i'm thinking about if the car was in Paignton rather than by post. Could it done on a while you wait basis? I get down to Preston every now and then so could pop over.

The problem I still have however (which is actually nothing to do with keys and the ECU swap) is that my chassis number isn't recognised by Tech2 as being valid for a desired gearbox software upgrade. So, it may be that that becomes the factor re the ECU swap rather than anything to do with keys - if you see my logic?

I haven't forgotten about that CCR8ooo BTW - that's planned for next weekend as part of a list of jobs to do!

Thanks .............. Rob

Probably only a couple of hours work tops - but if you are over this way at any time, give me a yell anyway
