Well there you go.
I thought it had to be done by testbook,,

Oh well, we were passing near Millicent anyway,,

This can be done either by switching on the ignition and leaving it on for five minutes, or by using TestBook. The vehicle immobilisation will remain active until the communications link between the BCU and IDM has been re-established.

CHEERS

That's just to re-establish the data link between them in order to be able to comunicate with the BCU... like some other things this statement from RAVE is inaccurate... that 5 minutes(or less) with ignition on is necessary either way cos untill the communication is not established between the IDM and BCU no tester will communicate with it not even the god of all TestBooks believe me...also the BCU must be programmed for the equipment of the car( fobs, suspension, transmission, etc) and the ECU must learn the new security code ... the BCU will keep the stored mileage just that if you only disable the odometer warning not syncronise it with the instrument pack there will be no problem cos if the mileage stored in the BCU is higher and you syncronise it with the odometer the higher mileage will be displayed

Cool. Thanks mate. So the keys fobs will still work without recoding them or BCU?

Negative

Missed that thanks. Cheers

So I've been chasing the source of a wet passenger floor, likely coming in around the air ducts.


Ever have this issue in yours, ozscott?


Might that explain the BCU failure?

Could be mate. My plenum plastic bottom cover is broken like so many...although my HVAC is constantly on recirculating to avert water coming in.

I would check the plastic blanking plate in the tray below the windscreen, this is where water can bank up under heavy rain if it doesn't drain away at the mudguard end drain holes of the tray .

Is the black plastic panel that blanks off where the LHD wiper motor would be installed.

Run some sealant along the seem. I've done it to 3 discos, so it must me a common problem and it lets water into the cabin .
