hi all a other question had the ocatvia II vrs diesel now 4 three weeks and i have noticed when i first start the once warm the car sits at 900 rpm at idol but once i go on a run and bring the car back to a stop it sits and idols at 1000 rpm anyone 1 no why ? as i thought it should sit at idol on 900rpm

Does your car has got DPF (particle filter)? If it's regeneration has started but haven't been finished then it might keep rpm around 1k.

Sure, I don't know how often have you driven during these 3 weeks and how long have your trips been. If quite a lot and for high mileage then this might not be the case.

yes it has got dpf i do short trips every day between 10 /30 mile but it seems to idol at 1000rpm even when warm after a run 

DPF regeneration happens when you are driving. When you stop at the traffic lights, there is ~1k rpm to keep higher temperature. When you start driving then the regeneration goes on.

After a trip you see an unfinished DPF regeneration (you can't finish it while not driving).

Might be that your regeneration starts but finishes only partly and therefore happens often. Might be crappy DPF sensor... the thing that makes everything a bit unclear - why haven't you seen a DPF warning? Or have you?

its seems to have gone back to normal at the min what has happened 3 times since getting the car is once i have stopped the car and turned it off got out i have noticed like the fan is running for a while i got told that was it doing a regen but not sure if thats correct but i done it last night and since then car is dropping back to 900rpm for now

Must have been the DPF.

Seems like it has succeded to finish the regeneration and that's why it's back to normal.

And the running fan is a usual thing to see after the regeneration.

hopefully thats what it was thanks again for all the help this is a top forum

Completely normal mate as above. My vrs does it every few hundred miles and is used for short trips around town and a road commuting. 

 

The the car will manage it itself even if you turn it off, will just pick up again next time. It also has a warning light that comes on if needed, but I've never seen it on mine! 

i have seen no warning light as of yet what is the warning light and is it warning of a regen??

Not exactly. It shows that your DPF is way to full to continue with an automatic regeneration. You must drive at at least 60 km/h with a ~constant speed at 2-2,5k rpm for some time until the warning disappears. If you ignore it then you will get another warnings, limp mode and the need for forced regeneration (can't do it without VCDS software). You better don't go that far.

ok thanks for that
