'99 RR 4.0 throttle surge & ZF22 fault message
Posted: Mon Oct 18, 2004 12:40 pm
This is a weird one, only just started happening 2 days ago but increasing in frequency.
When I slow down after driving more than 5 mins, almost to a stop (traffic lights or driveway) with foot off throttle and on brake, the engine does a little surge for about 1 sec - enough for the car creep forward (overcomes light brake pressure)
This accompanied by a quick flash of the orange engine icon on the dash. Then the next time it happens, GEARBOX FAULT appears in message centre. Once this message appears the surging seems to stop.
The tacho doesn't seem to move with the throttle surge either.
Turning off the ignition and back on resets the problem and the sequence begins again.
Any clues from you wise men of rover?
Thanks,
Hardy
