Is that true for JLR engines?

If so how did Powerful UK get fault messages relating to the GPF?

JLR's patent application includes the following:

"The regeneration of the gasoline particulate filter may be a passive regeneration which occurs during normal operation of the internal combustion engine when the conditions in the gasoline particulate filter are suitable for
oxidising the carbonaceous particulate material. Alternatively, or in addition, the regeneration of the gasoline particulate filter may comprise an active regeneration event when the operation of the gasoline internal combustion is controlled to create conditions in the gasoline particulate filter suitable for oxidising the carbonaceous particulate material."

I think it may change the fuelling (decrease fuel) to increase oxygen in the exhaust and thereby raise burn temps/allow more soot to be burnt in the GPF. If so it's the opposite to the DPF strategy and so understandable that it wouldn't have the same issue of oil dilution; that's not to say that there won't be other consequences to running the engine in a lean burn condition?

A few things I found this morning while doing my weekly check routine under the bonnet.........

A) I haven’t had a car with one of these in a long while - TBH I much prefer this to an electronic one as my experience has been frequent dash messages warning “Communication lost with oil level sender”

And its a long one too and also not easy to relocate after reading as the tube seems a pretty small diameter, it is also easy not to push it fully home and seal it, it’s as if it has a “click to lock” on it.

B) DPF on the 2.0ltr Diesel
Took the car to the village garage who are LR Indies and they spent and hour on Saturday morning climbing all over it and commented that the DPF is one of the biggest that they’ve seen and its among the closest to the engine/turbo that they’ve seen so hopefully oil dilution is a thing of older Land Rover products. If that is the DPF I’ve circled in the picture then it’s well above the max wading depth too.

C) The Auxy/ cam belts don’t look too difficult to access too on the front of the engine. - Please don’t leap on me - I’m not an engineer so the serpentine belt I saw might not be an Auxy/ Cam belt!

D) Screen Washer bottle - it’s easy to access at the front of the engine bay and either I have used more water/ screen wash mixture than I thought or it’s a huge capacity washer bottle! It isn’t huge it’s only 6.25 litres, still about twice the capacity of the washerbottle on my old 90 Pangea Green D250 90 HSE with Air Suspension, Off-road Pack, Towing Pack, Black Contrast roof , rear recovery eyes, Front bash plate, Classic flaps all round, extended wheel arch kit and a few bits from PowerfulUK Expel Clear Gloss PPF to come
2020 D240 1st Edition in Pangea Green with Acorn interior. Now gone - old faithful, no mechanical issues whatsoever ever but the leaks and rattles all over the place won’t be missed!
