VW Golf Mk5 Gt Sport 140 (2008) - Cuts out whilst driving!

Update:

The car has been driven around and left ticking over to get the fault to reoccur.

Eventually when ticking over it started running rough like i was only on a few cylinders, then it finally conked out and would not start again.

The only fault codes being picked up are glow plug related but they thing that has nothing to do with it, but suspect its fuel injector related.

They recommended phoning VW as they said there was a recall on my engine BKD with the fuel injectors - I rang but theres no recall for my car.

Its getting kept a bit longer to completely verify what the issue is.

The recall was on BMN I think - largely same but the 170BHP version and hence different injectors.

I think the recall is called 24S something. It was a remap with more fuel to cyl 3 on engine code BMY

Has the in-tank fuel pump been checked that it is pumping fuel when the fault is present.

Sorry, just noticed you said fuel pump has been changed.

I think there is a relay that controls it, might be faulty.

But certainly worth checking the pump has power going to it & is running when the fault occurs.

An update to this thread,

Got the car back and its running as it should so far, apparently after properly diagnosing the car it was the tandem pump.

The garage put a second hand one on and so far its not cut out, but will take it for a big run at some point to make sure everything is ok.

So, its had a new fuel pump and filter, relay, and now a tandem pump.

The most interesting question is why all of this happened - dirty or contaminated diesel?
