The car has started to, very occasionally, go into limp mode.
I start the car and it revs, then it sounds like something 'clicks', then it idles fast - the EML comes on (car with spanner through it).
The car will barely rev over 3k rpm and the turbo will NOT spool up.
If I touch the brakes, the revs return to normal, release the footbrake and the revs increase at idle - it's a fairly sharp jump of around 250 rpm (normal idle is 750 rpm). When the footbrake is depressed and I use the accelerator pedal, it does NOTHING - on either tickle, half or fully depressed pedal.
Any idea what could be causing this?
I have had a DTUK CRD2 box on for a couple of months which has been running absolutely fine (set at -1 then +1).
This issue has happened both with AND without the DTUK box on.
Any help/troubleshooting ideas welcome before I have to hand over some hard earned for some tech help at a stealers/specialists.
