Have patience untill monday then i'll make some tests with nanocom on mine to see how it behaves with a 100% working system cos i dont have much confidence in it when it comes to ACE, i'm asking again: ... that 20km/hr thing means that the...

I don't really think the pump was damaged albeit not impossible but as discussed in post #14 it's possible that the attenuator was somehow hurt and now it restricts the flow, unfortunately i don't khow how that feed pipe was built... i hope you...

You should have road tested it before diagnosing cos it's possible that the ECU had a hystorical fault logged.... the outputs should work only with relay in it's place... erase the codes and road test it then we'll speak

Maybe we understand differently how this works, once the air in the tank was pressurised to 1.4 bar due to the expansion of coolant i dont think that pressure will drop to zero once the coolant cools down cos then the level in the tank would drop...

Why? it's supposed to be a sealed system and the valve works with the air which is in the expansion tank , for example if you pump up a tyre to 1.4 bar and let it over night will it be no pressure in the morning?

the tank's cap has a pressure valve to keep 1.4 bar in the system so as long as the top hose doesnt become rock solid while driving and it runs cooler rather than hotter i dont think it's a HG problem which would create overheating or coolant loss

The mix must be 50% antifreeze(oat) / 50% water for the system to work as it should and choose the antifreeze temperature range based on that to achieve the desired protection, the refractometer test is irrelevant hence the note from the WSM...

Unfortunately i can't help you more with this as all i know to do on D4's is with a diagnostic tool, some programmings or pure electrical faults. When it comes to boost issues on these it's beyond my skills

the only one which seems OK these days is the PEM100990LR, that's what i have and as you saw the ECT is behaving well(with engine cover fitted and 50% OAT mix cos the coolant's concentration has some effect too)

It should have some effect IMO cos your's has a very strange behaviour exactly like you observed

You should try with engine cover on if you still have it, i cropped a section from an older log of mine when it was up to temp, the left column is the road speed and the right the ECT just to show that it's quite constant around 90 and so was the...

That's a bit strange, once up at normal running temp it's not supposed to drop so much at idle actually it should not drop at all, some questions: 1. the radiator is stock or some so called "uprated" alloy one? 2. what about the ECT sensor, is...

Seems very like one for vauxhall, see THIS

That's not a dedicated Discovery 1 rubber hanger for sure so you'll have to find some similar generic one if the original type are not good which means that maybe the exhaust was replaced too

Hi, IIRC the D1 electric seats adjutments are driven by cables like on the RRC and if it's so here's an ideea https://www.landroversonly.com/threads/broken-seat-motors-can-i-manually-adjust-them.41432/?post_id=340691#post-340691 so you might be...

I changed the flange when I did mine, it's cheap enough.

There are cases when even new seals can leak, for the reasons described: 1. https://ashcroft-transmissions.co.uk/product/lt230-front-flange/ 2. https://ashcroft-transmissions.co.uk/product/lt230-rear-flange/

As long as you dont get any response on output tests to the warning or solenoids with nanocom on a 100% good valve block you have to rule the ECU out first, discussions about the filter or hydraulics are futile
