P38A Transfer Box changed - some problems

Well, no matter what I try, I can't hear any motor turning.

That's gonna be the first port of call me thinks!

OK see what you get after changing motor.

Would it be particularly harmful to drive the car while it's like this?

That i cannot answer. Personally i would sort it first. But your call.

take the motor off, make sure the t/box is fully in high. Refit the motor to keep it in high and disconnect the motor's electrical connection. Then you should be ok to get to the garage. Did the motor work before? If it did I would be looking at the wiring as Wammers said.

The motor on it just now came with the box. Didn't swap over the motor from the one that was removed but that's the plan tomorrow.

It's driving around fine just now though lacking in performance and jerky changes.

Something is upsetting the gearbox ECU, either bad comms with the motor via the position switches in it, to transfer box ECU which would upset the gearbox ECU. Or a bad connection caused by the box being lowered to change the transfer box pulling on the loom and dislodging something like the CO673 plug. Which would give you your intermittent Hi/Low on Nanocom. If you have reset the gearbox adaptive values it will take time to settle down anyway.

Would you happen to know what the part number is for the transfer ECU on this car?

I might try and find one so I can replace that if everything else fails.

Yes replied. Along with latest ECU number. AMR6459. But it is no longer available new. Not at Rimmers anyway.

As mentioned, just checked it. No burning/burnt smell near it at all so hopefully it's alright.

Just need to wait and see what happens tomorrow morning I guess as I appear to have done everything else I can do!

A plethora of them on eBay.

Yeah - thank god!

Just back from the garage.

Plugged in the original motor and checked it moved first, which it did. That was then installed and the old one binned - everything back to normal now.

Changes over smoothly, no annoying warnings or dings and my indicator noises work again! A good morning indeed.

Of course, discovered a few other bits needing addressing while i was under it but isn't that always the case!

Anyway, thanks everyone for your help
