Replaced fuel regulator twice. replaced injector loom, did the oil pump bolt even though it was tight.

Do you have the acoustic cover on the engine??

No I took the acoustic cover off as the engine apeared to take a long time to cool down ( but never overheated) but the loudness was there before I took it off
its an auto and does take a few revs to take off the mark

check your mounts and your exhuast fittings, the sound of an engine can be "retransmitted" through the body work if you wind up with metal to metal contact to the bodywork/chassis.

What year is the vehicle? I have noticed a lot more knock and rattle with later (Post 03) Td5's. Maybe due to the fuel advance/ mapping. Tombie2 would be able to confirm this, as it is just an observation on my part.

Its a 2000 model and Iam confident that its diesel nock as I have owned a lot of diesel's over the years all the mountings through out the vehicle are in good condition therefore noise's are not being transmitted through the vehicle.
I was going to look at the waste gate on the weekend see if that has is working

My 1999 D2 TD5 gets a rattle up when cold but sliky smooth when warm so IMHO no they are not too noisy.

Another possibility is poor / incorrect grade fuel. My cousin used to run his on Jet A-1 as he got it from work, made i fair bit of knock, worst when cold

Same here.


But here's some further tips.

Keep the windows closed and turn the radio up a notch.

Then you can wonder why everyone looks at you as you drive down the street.
