2 months out of warranty!

[Oliver Ciaravella]

So we have a 2019 Navara with just 30k on clock.

We have owned since new and regardless of driving style have regular DPF issues which so far have been resolved by the garage.

Now the truck is in for an oil service and DPF light again. They are doing a forced regen and although tried to say they would charge I argued the case.

They have also now just said the Fuel pump is leaking and intercooler pipe is leaking oil.

Not happy being given a £2500 bill. I have asked garage to raise with customer care and I also have a few questions:

1) The DPF is a continual pain in the a%# regardless of the amount of motorway driving we still get this with half a dozen smaller journeys in the cold. I noticed the case against JLR about the DPFs and wondered if there’s likely to be a case about Navara my understanding is due to length of Navara and the DPF being at the back it fails to get hot enough - although I may be wrong here being no mechanic. If it is the case then surely this is a significant design fault.
2) For a vehicle hardly used for the fuel pump and intercooler pipe to go within 5 years and 30k surely this is not normal. My feeling is due to the number of regens this has caused the deterioration. Being out of warranty by 3 months how likely is it Nissan will cover this?

Thanks it’s such a shame but will be looking to dispose of truck once this has been sorted.

I've often quipped about a "warranty chip" particularly in home electronics, but that's all it is - humour.

Your issue sounds like an unresolved issue from during the warranty period. The DPF should not be this problematic and since we don't hear many reports of this sort of problem with your model, I'd suggest yours had an issue (perhaps with the sensors front and rear of the DPF itself) that was never addressed.

The DPF shouldn't be too far from the dump pipe. It really needs a lot of heat to do its job, it usually lives under the front passenger footwell and can be identified by a shield around a large section of exhaust with sensors on both inlet and outlet sides, plus a pair of steel tubes (about 4-6mm depending on model) that should wind up in the engine bay at a hall-effect sensor that measures pressure differential between front and rear of the DPF.

Personally: I'd take it to the dealer and tell them that their previous fix (which was within the warranty period) had not worked.

I guess you're in England because in Australia we pay for things in kilograms not pounds, so I don't know if you have anything like a "Fair Trading" government department that could assist you.
