Hello there!

I've been driving a Nissan Navara for the passed seven years. Its a 2012 V6 Diesel now with 178000 miles on the clock.

Its been a real workhorse and hasn't really let me down but lots of issues with the DPF and laggy acceleration.

Its had a fair few new parts ie. Lamda Sensor, EGR valve, DPF pressure sensor and multiple forced regenerations.

The EML goes off for a while and then comes back on always with laggy acceleration but sometimes it will just start performing normally with brilliant acceleration. Its been back and forth to Nissan and other garages, but nothing concrete as to the cause, only the DPF needs changing!! Fault code is always P242F.


I'm reluctant to spend £1500 if it doesn't fix the issue or its just a sensor thats the problem.

Please, any ideas??

It sounds like the sensors have been replaced. There have been a least half a dozen on here who have had this problem.

It is possible that an injector has gone faulty and is filling the DPF with soot. Pre DPF you could tell because it smoked a lot. What is the fuel consumption like?

As you say, it could just be a failed DPF, I didn't know they were so pricey.

If you are in the right area, it might be worth getting billcar in Shrewsbury to look at it. They are the D40 experts!

Thanks very much for your reply!

No smoke whatsoever, but consumption its running like 24 mpg!

I live in Kent so if you know of any specialists in the area, any info would be much appreciated.

If the DPF was the issue then why would it perform randomly? Strange!!

Ok so as if this couldn't get any stranger, today the EML has turned itself off and the truck is running great!!!

No idea what is going on 😂

The thing with DPF s is that they soak up all the smoke. So if something isn't right which could cause smoke, all that soot ends up in DPF.

24mpg would suggest that something isn't right with the tune. Maybe a leaking injector or a sensor out.

I know Kaisermotor on Kent have some good D40 experience.
