double the diesel cleaner, fill your tank full with good diesel, Then take it on tthe motor way and drive the nuts off it and shift down a gear and run at max RPM for 50 miles or so. this will get your DPF up to temps and burn it clean, and the exhaust pressure will blow out the carbon/dust in the DPF and your muffer, as well ascleaning your injectors, also change all your fuel filters

how? What do I need? Mate suggested taking it out and putting it in diesel over night? Or how would I go a long doing this?
didn't know a diesel had a cat? DPF and muffler yes. I believe the DPF is the desiel=of a cat (like a petrol)

No clue, sorry! I'd suggest you need something with a bit more gusto than diesel, there's various off car cleaners on the market, dunno how good they are

Think the more modern ones have a NO (nitric oxide) reducing cat

What did you forget ?
DOC = diesel oxidiation catylist, first thing in the exhaust pipe, dont think new kit has them anymore but could be wrong, fitted on land rovers from 300tdi onwards, early td5 (Euro2) didnt have them, later ones (Euro3) did.
DPF = diesel particualte filter, this is the one that needs cleaning, from 07 (Euro4) onwards
I think Euro5 was basically Euro4 plus stop/start?
SCR = cat this is the one that transforms the nox using adblue, 2016 (Euro6) onwards, for trucks Euro6 came out in 2014 and has been nothing but a pita ever since.

On the subject of engine oil I have a late model defender that specifies WSS M2C913B or C for Non DPF vehicles, and WSS M2C934 B for vehicles fitted with a DPF. I believe these are Ford oil spec reference numbers adopted by JLR. My vehicle has a CAT and a DPF and requires a 5w/30 oil. I have started using as per attachment, its a low SAPS oil for DPF vehicles. DPF regeneration is done automatically by driving at 50+mph for a good distance (italian tune up) - when it needs a regeneration the engine management detects it and will adjust the burn temperature up to clear the DPF. I'll see if I can find some more info on this bit.

Please do!
if cant get mine to regen. Will try with the new diagnosis system. But the 2500 rpm for 20 minutes doesnt work for some reason. As I mentioned, my mechanic insisted he did to succesful regens on it. He pointted to the sensor which I changed. So a bit stuck
great bit of info ,thks
Is it correct that u can’t blank egrs if there is a DPF fitted , also strange that some of the early 2.7 D4s didn’t have DPFs
Many thks as always
