I'm holding out until I get pp2000 working on Friday but I get the feeling my idle speed of 900rpm when warmed up is high. If it were a petrol car I'd say it's not going to closed loop mode and I would blame the coolant temp sensor. Driving at low revs is hard work.

What's your 2.0 hdi idle at when at operating temp (which for mine, with a new thermostat is about 83 in 1 degree weather)?

is it a 90 or 110 bhp. So 90's have a throttle cable which could be too tight.

on the Bosch system hot Idle is set in ecu to 750 normally but if engine is under high electrical or other load revs can rise slightly.

It's a 90, no throttle cable. Fly by wire so all ecu controlled. Driving today it never stops below about 910

Mr Haynes says idle speed of 800 + or - 20.

I have the same car - needle hovers just below 800 - operating temperature is 75.

There's not much needle space between 820 and 900 - if pp2000 says nowt I'm not sure I'd be worrying about it.

Yep, i can confirm this is what its doing. I have PP2000 now so hopefully i can make sense as to why its running awfully.
