Malfunctioning Exhaust filter

I have a 2015, RR Vogue 3 litre which I have owned for about 18 months. No issues until this May when the 'exhaust filter full contact dealer' red warning light came on and the car went into limp mode. Took it to my local independent LR garage who flushed it through and all was well. About 1k miles later the light came on again and again took it to the garage and they flushed it through and told me there was nothing wrong with it I just needed to drive it more at higher speeds! Now I have literally done another 200 miles and the light is back on and the car is in limp mode again. I now don't really trust my usual garage any more and the LR garage will cost a fortune so any advice? There is another independent garage locally but not sure the car will even make it there - will cars make a 5 mile trip in limp mode? I usually drive about 100 miles a week and at decent speeds. I have seen a local company which specialises in ECU and DPF solutions so not sure if they are worth contacting to have a look, thanks for reading.
 
If any doubts with the dpf itself, it should be removed, tested and cleaned professionally.
It is a consumable item unfortunately and at expense.
A few things to bare in mind with a dpf.
They can crack inside due to blockages and overheating.
The wrong engine oil,
Defective pressure sensor and it's pipework,
Short journeys and age.
I hope you get it sorted👍
 
Short journeys really screw them, especially the Ford engines with Adblue.

You need the revs up near 3000 rpm. A blast down the dual carriageway once a week in a low gear seemed to work for our work trucks.
 
In my discovery 3 TDV6 owners manual is suggest that you run the engine at above 3000 rpm for about 20 min to burn out the acumulated carbon but dont park over dry grass
 
I have a similar problem with my 2011 TDV8, see my "broken down in Belgium" thread! I mentioned on there that a lot of the modern buses I drive have this problem and they do a regen on them which involves running the engine at high revs for about 20 minutes. Some do it automatically, the temperature will melt a tarmac surface, see comment above about grass!

I think my car was previously used for "shopping" and not really had a good run for a few years. My high speed thrash across Europe at night seems to have shifted a few cobwebs. Buses never get hot enough in town traffic for the adblue stuff to work properly, same with shopping cars, the odd local trip or taking Jimmy and Jemimah to school doesn't do the car much good.
 
My son had similar DPF errors on his previous Jag XF. Most of his journeys at the time were 4-5 miles twice a day to & from work. Regular blasts up the M40 after his girlfriend moved to Buckingham cleared it with no garage visit required.

By the way, this is not entirely relevant, but I would like to share a good entertainment platform. When I need to relax and take my mind off things, I visit this website. It is exceptional in its own way, offering numerous games and many attractive bonuses. Therefore, I recommend giving it a try.

Looks like you’re dealing with the classic modern diesel problem. Around town they never really get up to proper temps, so all the emissions systems end up clogging or acting up. Give them a proper motorway run every so often and they behave way better — these engines just aren’t happy with short trips.
 
Standard procedure . . . dump all the particulates in the counrtryside rather than in the towns !! I asusme overall pollution must be similar to a pre-DPF car !!

As has been said peeps who buy a new modern diesel and do short runs will come up against the DPF issue.

Now as for the pollution being somewherelse is a good question.
But as the DPF burns the particles at a higher temp they "should" be smaller and perhaps less of a problem, :vb-confused2:.

Its all a bit smoke and mirrors really.
