Last year I took a CDTi up to Frank Massey in Preston who specialises in diagnostics & PWM's etc. He even runs Diagnostic courses for garage techs.
He thought it was regulation but we ran out of time to look further.
I would like to swap a high pressure pump assembly from an CDT that doesn't have the Whine to a CDTi ??
Any differences as far as you know. Rail pressure's same as its just a remap?
I'm going to do a visual now on a CDT & CDTi to see if I spot any differences.

If it only affects 20% of facelfited models, maybe its because this 20% are using new parts (different supplier?), whereas the others are assembled from the parts used on the prefacelift cars. Or maybe only 20% of facelfited models have only one low pressure pump and the associated piping.
