Re: DPF Fault !!!!!

Have been keeping an eye on when my regens happen this month although only way I can tell is by the much increased fuel consumption. I've never had the light on to tell me the DPF is full.

Car hasn't been used a great deal this month apart from frequent journeys to the gym which is 16 miles, 90% along dual carriageway but with 8 roundabouts to negotiate but very little traffic. There was 130 miles between the last 2 regens, both of which were no doubt interrupted hence dumping copious amounts of fuel into the oil.

Historically I wouldn't regard these journeys as particularly short but evidently they are far too short for this engine.

I did 45 motorway miles yesterday, then 3 short (3-5 miles each, in and out of town) then on the 12 mile trip to work (40-50mph B road) it decides to do a regen! Go figure!

It has two options to active regen according to JLR docs
It's met the pressure limit
It's 250 miles since the last one

There's a mileage trigger too at 250 miles, so full DPF or not your going to get a regeneration.

The DPF software incorporates a mileage trigger which is used as back-up for active regeneration. If active regeneration has not been initiated by a back pressure signal from the differential pressure sensor, regeneration is requested based on distance travelled.

It would be interesting to find out how much diesel is injected into the engine during a regen. If it's triggered every 250 miles, then over 84 cycles between theoretical services, little wonder the oil is seeing dilution! Assuming the mean average of members on this forum reporting circa 12000 miles is throwing the oil service, thats still 48 post combustion injections of diesel.

I wonder just how much diesel a regen uses to burn the soot off.....if we could find that out, it wouldn't be difficult to calculate back just how much is going into the sump.

The car has been into the dealership and one of the sensors was replaced. At the time we were told that this would solve the problem. Surprise, surprise, the problem still exists.
The mechanics at the dealership have told my wife and I to drive the car at a constant 90kph for 20 mins which will clear the amber warning and facilitate active regeneration. We have done this twice now and sure enough the warning clears itself only to return after 1 week of town driving (45 klm). The car has been into the workshop (6th time) and the test equipment indicates that regeneration has only been successful once.
Before purchasing the car and as most people do, I read many articles, reviews and the usual land rover documentation and did not see any mention that consistent town driving would lead to this issue. Land Rover Italia have been made aware of the issue and at the moment, I am considering the replace the car with a Mercedes GLC.

you might want to get yourself a coffee or a large glass of your favourite tipple and read this long thread .

It is possible you were misssold a diesel and could have some recourse depending on the laws in Italy. Uk owners have successfully rejected vehicles as "not fit for purpose" as no warning was given about what JLR call "driving style" in their advertising material. This is admitted in JLRP00100 download/file.php?id=5997

Rejection due to exhaust filter (DPF)

Post by dsaus » Fri Feb 16, 2018 6:58 am

Why can't JLR Australia make a decision about a costumer complaint
We have been emailing them and calling since October and they have gone quiet will not answer emails or return calls as promised
We have a case number since the first email yet as of today they still cant sort it out ?
I think i have spoken to every employee in the office its getting beyond ridiculous
next step is legal action
Has anyone got any advice on this matter ?

From what you have written and bearing in mind that you seem to have done everything reasonable possible it would seem to me that the the only road you can go down is the one of legal action.

Not living in Australia I'm afraid I have no idea what this involves but I'm sure that someone else on here living there may be able to help.

Good luck.
