The technicians currently reckon that the reason the TPM does not work is due to a dirty ABS sensor. It begs the question of why the little goblin in the engine bay sees that the car is moving forward but does not notice that the ABS doesn't see the wheels turning. If it did then it could tell someone that one of the safety systems, the ABS, is not working correctly.

The ABS sensor has been cleaned and I have been asked to see if the fault occurs again. If it does then the next step is apparently to replace the drive shafts.

I'M with you on this....I can't see ANY way in which the ABS sensor can assist the car in knowing what the tyre pressure is ... at all.
The only up side to that statement is that its only slightly less daft sounding than the fault lies in the driveshaft.

Lets know how its resolved.

Cheers

The ABS sensor has been cleaned and now the wait until the tyre pressures drop. I have tried hard braking at 40mph whilst steering and there seemed to be some ability to steer but it was not a good test as it was a dry road and brakes that are really good stop the car within a few lengths. I have noticed that the electronic stability control lights up on the dash over some really steep road humps but it may have always done that and I may just be noticing it. Apart from testing of the sensors does anyone know of a better test for the complete ABS function?
