    Is there anything you can do to maintain the DPF system other than the normal car regen process?

    You can have the DPF unit cleaned and flushed as a form of preventative maintenance. There are plenty of mobile or garage based services that offer professional DPF cleaning. It doesn't involve removing the DPF unit as it can be injected with cleaning fluid and flushed out when still fitted to the vehicle.

    Professional cleaning clears out any soot, urea crystalisation and ash build up from the DPF. It can help prevent (or resolve) common DPF faults by removing those harmful but inevitable deposits. It's relatively inexpensive, probably £200 or there abouts...For garage based DPF cleaning services, it's usually a drive in, drive away process and doesn't normally require leaving your car there. Mobile services can do it at your home or even at your workplace in some cases. It routinely takes around an hour.

    I flushed mine out myself as part of a complete service after I got the Bling Barge home, same method as shown in the video below.

    If you check online, there'll probably be several garages or professional mobile DPF cleaning services near you. Have a chat with them on the phone if it interests you and they'll explain the process and what it does and doesn't do.

    I'll post this up purely as a rough visual example of in situ and on the driveway DPF cleaning on a D5....

    It's possibly a sticking throttle body valve which is a fairly common cause of DPF fault indications as it soots up and the butterfly valve sticks...which can be cleaned and repaired but only as a temporary measure.

    Replacement throttle body isn't cheap...especially from a dealership... but nowhere near the cost of a DPF unit Thumbs Up

    Average throttle body price from indy suppliers is around the £500 mark for a genuine LR part..around £100 cheaper for after market.

    Throttle body from main dealers in Leicester to my garage £280 plus vat i was v surprised at that but all fitted and hopefully sorted

    Nice one...strangely enough I had short listed a very nice 2018 HSE at Marshalls in Leicester (through Autotrader) just before I opted for the one I have now. It had a bit higher mileage than I ideally wanted but I loved the colour...Kaikura stone or something... a light bronzey metallic Thumbs Up

    I think many folk overlook MD’s when comes to parts and service. Yes I know they can be very expensive on both counts but not always. I’ve have had many a bargain from Duckworths particularly on accessories.

    Parts perhaps...but servicing or repairs? Dealership workshops almost invariably take way too long to complete simple jobs or resolve faults with the consequent labour charges to suit. Fine if you're lumping it on a warranty claim or can afford to lose your car for several days.

    Two days and almost £500 to replace a faulty window regulator is only one example I've seen (with a standard £50 diagnostic fee)...it's a half hour DIY job that needs only 2 Torx bits to strip and reassemble... even assuming it's your first time doing it. Diagnosis? Press the button and the window doesn't go up or down...that'll be £50, please. Rolling Eyes

    Veering slightly further off topic again, as a mobile fitter for a large commercial 4x4 hire company in a previous life, if I'd taken anywhere like the amount of time or liberties as a dealership in diagnosing and resolving faults or breakdowns, I'd have been handed my walking papers. I'm not talking about bodgeit and leggit jobs either, two of our main customers were British Gas and the Electricity board with over 300 4WD (or 6WD) hire vehicles on-site all over the UK at any one time, they paid a lot of money to have working vehicles 24/7 so we didn't really have any leeway for vehicles breaking down through lackluster servicing or maintenance...

    I took a small bit of pride in my 0.2% callback rate as a fitter during my time there. That 0.2% was one TD5 110 Defender that I had fitted a new clutch in on-site and got called back to it 2 days later with a worksheet that simply stated 'Stopped working'.

    I discovered after getting back on-site that some nice Electricity Board linesmen had tried to deep ford it through a peat bog and it it had injested a few gallons of silt with the consistency of grinding paste through the air intake...'Stopped working' indeed...I had to condemn it and shove it on a trailer...after we dragged it out of the bog with a JCB Neutral
