I was a LR master technician before leaving to work for Audi. The DPF issues they have can be easily solved by having an awareness of what your car is doing. I’m not concerned about ash mass build up as your engine needs to be burning oil for this to happen.
That'll work alright. On diesel Ingeniums there are reports of timing chain breakdowns, could be the result of extended OCI by JLR. Be on the watch. Mine is a gas/petrol, no bad reports on both sides Jaguar & LL forums. Seems solid and dependable engine.
