Im not concerned about giving the new filter and oil a short life. If leaving this for 10,000 miles and doing the oil and filter again will remove that gunk, that would be a great result. (Although the filter replacement is a B*I*T*C*H - took me all day)

Changing the cambelt on a TD4/SD4 is straight forward (i did it myself, just followed the instructions - the engine is nothing special - the DW12 is a Peugeot /Ford design used on thousands on non-Landrover cars. Bread and butter work for a competent mechanic. Very surprised they wont touch it. Personally I'd steer claer of LR main dealers and seek out an independent LR specialist. I had an issue with my Haldex and took it a independent LR specialist - he changed the massive flange for the smaller one FOC - made no difference to the car and I can get the pump out now without taking the haldex off now.

The pump really does need removing, as the screen clogs up with bits that won't break down.

Some of the debris collected by the screen is the surface of the friction material from the clutch plates that is part of the Haldex. They’ll never break down and need removing hence the changeable filter and cleanable screen. |

Would it be safe to conclude that the oil flows through the pump first and then through the (main) filter? This seems the only way this stuff could get there and also as the pump is low and the filter high seems to be logical. |

The fluid flows through the pump screen, then through the pump itself, before going onto the filter and then the fluid gallery. Hyundai Ioniq 5 Ultimate. The replacement for the SE.

Where abouts in country are you? There are a few places around that specialise in 'euro' cars - these guys are likely to be the only ones that even know what a Haldex is.

If you have the belt and its overdue a change why not have it done now?
