Who replaced the cat and DPF sensor ? were they showing as faulty .? Have you scanned for fault codes ? replaced fuel filter ?
Posted Jul 21, 2023 (1 year ago)
The Fault Code was for the DPF which was 57% blocked, and as the Catalytic Converter and DPF filter are all one unit, it got flushed out by using DPF cleaner for over 6 Hours, but it still never regained its power back
I was the one who replaced the Cat and the DPF sensor, After a Main Dealership tried to rip me off on the price of the cat, (nearly £2000).
they ran a diagnostic test, but never actually found out what was the real reason.
The Master Technician's report report said that the cat and dpf sensor needed replacing

Assuming that year has a timing belt . if not been replaced and worn , it could have jumped and thrown timing out which would affect running .

how would i find out if the timing belt has become defective???

Timing bely should be changed at certain intervals dependent on mileage or after so many years . They can get worn ./ stretched and jump timing teeth .

for oil pickup problems concerning low oil pressure .spoon of acetone every morning on first start directly into oil do this everyday until you get no more low oil pressure warning then stop using acetone as this swells the rubber seal preventing low pressure
