My car has been idling higher than usual lately at random times. It will idle around 800 rpm when warm and uses around 1.0l/h - which is normal, but randomly will jump to around 1100 rpm and uses 1.5l/h when idling until I turn off the engine. When I restart the engine it will go back to normal until it jumps back up again. I plugged in vcds and it shows that when the car is idling normally, it will read 'idle'. But when the idle randomly jumps to around 1100 rpm whilst still idling, it reads 'part throttle'. I'm stumped for ideas.
The codes I've pulled are:
00282 - Throttle Position Actuator (V60): Implausible Signal (Cleared but hasn't come back after I drove it around today)
This is a new one that just popped up
01314 - Engine Control Module
013 - Check DTC Memory - Intermittent
Any help is appreciated!
Thanks
