More on my Ducato x244 2006 2.3 Diesel Starting and dying at low rpm issue …

Since the issue first started to occur I have replaced the fuel filter, the fuel pump relay (T10 I think it was) and the starting motor and driven over 1,000 miles since, so 99% of the time the van starts and runs very well, but sometimes it is reluctant to start, it turns over fine. I suspect a fuel issue.

I have listened and I can hear the fuel pump running when I turn the key, but maybe there is an intermittent fault. The other thing the van does is, if say I am approaching a roundabout or junction, I tend to pop into neutral and coast the last few yards, sometimes the engine cuts out and as a result the steering and braking become heavy, sometimes I can bump start and carry on, other times I come to a stop then turn the key, so far the engine has restarted after a few turns.

When the van is working well the van starts straight away which is most of the time, but obviously something is wrong and is slowly happening more often.

I think I can get to the fuel pump through a plate near the passenger seat, I will be trying this over the weekend. Not sure what sort of High Pressure pump I have, looks like there are individual pipes to individual injectors, so at the weekend will take covers and hoses off so that I might see where the pipes go. Any advice appreciated, and particularly where I might find the HP pump.
 
I would suspect air or throttle position sensor.

I had to remove my turbo intake hose. I had a nest built in mine whilst I had the airbox out for weeks.

Whilst that might not be your problem, it could be an air issue.

Check that turbo intake pipe and replace air filter if it is due or dirty from dust.
That would be my first check.

Also, I think the throttle is electronic.
I think you can recalibrate the throttle?

Also...Probably buy MultiECUScan diag software and a VAG switchable diag cable.
Yuo can get all kinds of readings if you have a laptop for the programme.
It gives you a view of what is going on...
