VW T5.1 2.0 Hot Start Issues and Erratic fuel pressure

[ArthurKing]

Hi

I have a 2015 T5.1 CAAC with 102k miles.

Owned about a year and always had the odd time is cranks for ages but it seems to have got worse.

Symptoms are:

Cold start fine
Drive van even 2 miles, leave it 20+ mins and it then takes ages to start. Cranks fine but takes 10+ seconds to fire
Hot immediate restart is fine, only happens if you leave it for a while

VDCS shows

Erratic fuel pressure even with engine off. Fluctuates from 60kpa to 400 ish.
Cylinder 1 shows high injector reading, 2.6mg.
Cylinders 2-4 show -1.2, -1.1, -0.3

Changes fuel pressure sensor. No difference

No error codes showing

Drives ok, perhaps a bit sluggish but could just be overthinking it. Nothing obviously wrong when driving it.

Garage wanted to remove HPFP to check for metal filings as a next step?

Check the fuel filter for sparkle dust, if present replace the HPFP and pray the dust didn’t get into the injectors.

the fuel pressure control valve and the fuel metering solenoid and inter connected and has 2 different switched earths at ecu numbers b45 b60 needs to be checked out
