If you like the car then I should fix the angle gear and see what happens.

I like the car, I'm just concerned that fixing the sleeve still might not fix the AWD because of the DEM code, even though I've had the DEM repaired.
Just reading the DTC readout from VIDA and it says 'The DEM indicates to the BCM when four wheel drive is activated. A DTC is stored if the BCM registers that the signal from the DEM is missing, or if the signal indicates that four wheel drive is not working'
So my question is can the signal to/from the DEM to the BCM be working, but still throw a code if the four wheel drive isn't working (e.g. due to stripped sleeve) How does the car recognise that the four wheel drive isn't working if a signal is present ?
