Engine warm and ticking over, you need to carry out the low orbit test, this consists of loosening the oil filler cap but leaving it in the hole, if the cap does not get blown off into orbit then you can safely say the rings/bores are okay.
Not very scientific but a quick check.
Have you taken it for a run to make sure the thing gets hot and the exhaust is clear of any old fluids/junk etc?
Pressurising when hot?
Checked cambelt timing?
Any unusual noises idling/driving?
Air filter clean?
Any recent engine work, or any work at all in the engine bay?
Fuel filter, and or crap fuel/fuel bug?

When you say you blanked the lower part of the egr valves how exactly have you blanked them?
normally you remove the flexible pipe from the egr to the throttle body each side and blank the four holes with a kit.
sometimes the kits aren't very good and you can get an air leak on the throttle body blanks that will cause problems.Andrew

Thanks for these pointers. Handy as a way to test compression as I dont have any tools for that. Is this just at idle?
I’ve not taken for a run yet purely due to the amount of smoke produced, it will easily fog the road!
I ran up to temp on the drive and the warmer it got, the more smoke so I was thinking maybe head gasket but there’s no obvious signs of milky sludge and I’d had to take it to a garage to test.
I’ve no way of checking cambelt timing, again would need a pro for that. It had a new engine at JLR at 95K miles following the incorrrect fitting of a timing belt. No record of a change since and its now at 190K, it was going to be the first job on the list until the problems running started.
When given a rev on the drive there is pinking. I’ll try and upload videos to my google drive and share the links.
Air filter is clean as is maf and the new MAP sensor.
Last work by previous owner (I’ve had it a few weeks) was a plastic housing which looks to be the thermostat under the throttle body but no other obvious signs of work.
Now, fuel... I filled it at a BP near me that I dont usually use but was heading to Liverpool so filled it there.
Definitely the right fuel but someone else has pointed me towards this as a possible cause. I’m going to drain some out of the filter and see what its like.
Again, thanks for the helpful pointers, I’ll work through these today.D3 G4 Selections car ‘08

I had the BAS patch for off road use that does the necessary electro stuff to fool the ECU. Before this, the lower part of the EGR pipes had good quality blanking plates fitted between the pipe and the EGR.
The throttle body butterfly was removed and spindle refitted.
The pipes connecting to to the throttle body at the top were reconnected as was so the only material changes were the blanking plates and the butterfly. The MAP was then applied.
The car has now been put back to standard, blanking shims removed and map is back to standard. The butterfly was reinstated via a complete replacement throttle body as it was easier to swap the whole item.D3 G4 Selections car ‘08

If its smoking more as the engine temp rises, thinking possibilties
Turbo worn - as oil warms up it gets thinner and more oil can escape past the spindle into the exhaust
engine breather / oil separator blocked?
worth checking these out even if it only eliminates these as possible faults.1994 Defender 300tdi 110 commercial

Well, reblanked the EGR today as I’m convinced they are not contributing to the problem and whilst swapping the throttle body for one without a butterfly, a whole lotta oil came out. I also noticed a reasonable amount drained from the bottom of the inter cooler to inlet pipe.
A reasonable assumption is blocked breathers or knackered turbo but either way I’m out of knowledge and talent to fix this so it will be going to James at Henshall Engineering for him to investigate and fix.
Thanks for all the pointers and help so far, much appreciated.D3 G4 Selections car ‘08

How many times do you search for a thread with the same symptoms that your car has only to find no resolution....?
Well, this one is different, the problem turned out to be a dead turbo. Not the best start to D3 ownership but there you go.D3 G4 Selections car ‘08

Well at least you're there now but the turbo's don't really give that much trouble beyond sticky vanes/actuator.

To conclude this sorry tale, I’m very pleased with it now!
Since the last post its had a new turbo, new brake lines, new suspension arms, timing belt and oil pump, all new filters and all the talc that goes with this amount of work. It drives superbly now, first proper drive today and I’m impressed with it.
One happy D3 owner.D3 G4 Selections car ‘08
