#1: 2.0 hdi lumpy idle + stalling Author: Nath189, Posted: Wed Oct 22, 2014 5:54 am ---- Hi all over the past two days had this fault with my car, it's when I'm pulling up to stop in traffic or at lights. the revs start bouncing down juddering the car and stalling it. It only starts to happen once it warmed up. Anyone had this before?
In the last 3 months it's had a coolant temp sensor so can't see it being that. I did put a cone air filter on on Sunday but took it off last night thinking it was sucking to much air. And changed the aux belt to a smaller one due to air con pump bearings whining. Any help would be appreciated.

I would start it up it from cold it would be OK then second set of traffic lights or third it would start with the revs jumping then cut out. took it to my mechanic and he changed the fuel pump regulator and it sorted it sadly it was a recon part he used so had to have another one a few months later.

#6: Re: 2.0 hdi lumpy idle + stalling Author: Nath189, Posted: Wed Oct 22, 2014 5:49 pm ---- I had a look at the live data reading and the fuel pressure drops when the engine is juddering. As I've had the car a year and no real detail in the service history, i start with a filter then pressure sensor and so on cheers for the help guys
