Wow, 11/06? Mine is 04/06. Yours has be one of that last ones built.

Ok, I had this once in four months when a tyre went really low pressure and I had the tyre pressure light as well. Since four new tyres, this is now a regular event, is that just a coincedental thing?

X5chemist, the lights come on way before the stall happens, as to codes, would they show up on the cluster readout? If so, then there are none. The shudder is not under braking, it is around 80-90 km/h (50-55 mph), then it smooths out. All the wheels are balanced, but I did not have a wheel alignment at the time.
The last independant mechanical report gave all the front and rear bushes, tie-rods and ball-joints a clean bill of health. It did say the disc rotors may be in need of a skim with the next set of pads but there was no evidence of warping on either end.

As I said before, if the lights come on and I have no issues as I am driving at road speed, there is no shudder at all through the speed range.

The type of stall you describe sounds like cam position sensor.

Miles and had it ever been replaced?

andrewwynn, would it be worth checking the lead connections and earthing points? As to cam position sensor, excusing my dumbness on diesel but is it still applicable? If so where are they, and I have no idea if they have ever been replaced.

I know when I am in the car and it is in park or nuetral, it will rev to 4000 rpm without any problem, I can even hold the rpm at any point in the rev range iand it will stay there without fluctuating. Put it in D and it may or may not respond at about 70/30% right now. That is in the positive!


Additional information, I did put the monster through a high pressure car wash and di an underbody clean could I have got water into something and FUBAR'ed it?
