2006 Defender 110 Td5 USW Zermatt Silver

What make of filters fitted.
Did it include fuel filter
How quiet is fuel pump
Injector loom changed recently
Have checked/cleaned crank sensor

Is misfire only since service?

Hi Andy
I will check all the above👍🏻
iIt has had new filter when the service was done just before I bought it.
Not sure what parts the used
Not check anything was looking for pointers first 👍🏻
Driving under normal conditions it’s fine
I had to go a run on the motorway that’s when I noticed.
Cheers

If it is always at high revs check your turbo wastegate is freely moving, and I’ve known cheap fuel filters to restrict fuel
