Hi there good morning to you and sorry for the delayed response
Ok is the noise only eveident at idle and goes away when you lift the revs to around 1100 rpm
Is It a drumming type noise
Does pressing the clutch pedal down make any difference to the noise
Regarding the starter issue is it intermitently not catching or noisy when trying to crank the engine

Yeah noise goes away at 1100rpm and starter issue is itermitently not catching
Hi there good evening to you and sorry for the delayed response
ok the drumming type noise you hear is from the accessory drive belt with the engine at idle, the cause is a high accessory drive belt excitation caused by crankshaft vibration being transmitted into the accessory drive belt drive.
Or belt flap as its commonly known The drumming noise only occurs during idle and should disappear at engine speeds above 1000 rpm.
To resolve this issue a modified crankshaft pulley together with a new accessory drive belt and accessory drive belt tensioner MUST be installed, (at the same time )without exception. The reason for replacing the accessory drive belt and the accessory drive belt tensioner is because they will both deteriorate after prolonged exposure to belt flap.
Regarding your starting issue this will be caused by worn dual mass fly wheel teeth
This usally damages the starter motor teeth causing difficulty engagement /meshing between the starter teeth and flywheel teeth
As yours has had a starter motor this is s tell tale indication of flywheel failure
If you need anymore help or advice on this issue please let me know
If you are Completely satisfied with my answer /advice

It's had new luk clutch and flywheel
Hi there
Sorry it didn't state you had replaced the dual mass fly wheel
So the starter and flywheel have been replaced but the intermitent starter issue persists
Does the starter make a whizzing noise or does it turn the engine slowly then it fires into life

Whizzing noise starter was put in 1 week after new clutch. And had new tensior and pulley
Hi there
How long after the starter was fitted did this noise appear
Did you also have a crankshaft pulley and tensioner fitted to cure the drumming noise (was the belt replaced at same time

Few weeks maybe a month-after.
Hi thanks ***** would replace the starter again using the warranty you got with it as I assume it was a non ford one that was fitted
I have seen non ford diesel starter motors last a few days before causing issues so would definitely be replacing the starter again
As the non ford ones are no -where near as strong as the ford ones
