yes these pressure sensors were swapped and even replaced before

and no i never swapped temperature sensors, they are all "baked" to exhaust pipe so strong that i was feared to broke them

anyway today i put back original software (without egr off and remap) to ECU and order one new EGR valve to replace broken one as i found some similiar issues with remap or EGR off on cars with DPF and all these troubles started like 1500kms before EGR off + remap

GraemeS i found that you trying or did EGR off on car with DPF right? if yes everything working ok so far?

thank you

Mine's a 4.4 without DPF and still has EGR operational.

Can't talk about the 3.6 but on the 4.4TDV8 the sort of problem you are having would typically be an air system leak. Suggest you try to get a smoke test but it would need to be a high pressure smoke test. Low pressure smoke tests won't be good enough to find a leak.

Not sure that the 3.6TDV8 came with a DPF here in the UK so possibly not too many people have your set up (3.6 with DPF) but I may be wrong.

. Cheers, Greg
