Hi all,

Quite often my Mk4 Golf GT PD150 will start idling at around 1200rpm, then it will settle back to its normal 800ish rpm, still drives fine when it does it but surely cant be normal?

Any ideas peeps? I done a quick search but cant find anything... Cheers [Y]

Most likely cause is the coolant temperature sensor. Any plug in scanner should be able to confirm it.

For the PD engines, that sensor is the correct one, including the ARL.
