Hi all
Last year almost to the month my car started what felt like a miss when accelerating followed by the M&S lights coming on and then full stop.
Re-start and all normal, good old diagnostics said driver demand? Changed waste gate control valve and it was better but not cured.
Then the issue went away and came back this month, so far i have done the following:
New MAS
EGR removed
New fuel filter
New fuel pressure regulator
New battery
Now it's slightly better?

Any ideas where to look next please.

The truth will be in the early morning drive, perhaps I'm

And today the problem is still there, Kangarroo city.
The injection harness is fine, as for the auto box, we are unable to find any harness etc on top of it?
I like my truck, just very dissapointed that I cannot fix, on a Nanocom all it comes up with is code:9493 and driver demand?

Solved, all these problems were down to the MAS, different car ever since, took 2 days for the ECU to recognise and problem cured.

driver demand from the diagnostics is the throttle pedal potentiometer
