Thanks Aguiness...

Yes, there are plenty companies that can chemically clean dpf.

Was wondering if that had any impact on reducing the number of dpf regen cycles and thereby reduce the frequency of oil changes/early service inducatoe.

The best way to keep the DPF happy and avoid early oil changes etc., is to drive the vehicle for more than a few miles at a time. These things don't like lots of short journeys and it's worth remembering that the V6 diesels engines are quite old in design with just emissions bits added on over time. So drive it for an hour so that it gets hot, everything gets a chance to do its thing, the DPF stays clear etc. If you live in a city centre and only do city driving, you've bought the wrong vehicle I'm afraid. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Well aware ofvthat RRSTDV8 mate..

Even the question is one of dpf regen frequencies. If the dpf capacity is such that it requires regen every 250-300 miles, then that with my driving should equate to once every 2 weeks not once every 2 days.

If dpf is full of ash deposits it reduces capacity for soot and also will affect air flow and back pressure...the pressure sensors then probably think dpf is full because ash deposit build up has accumulated over the years as ash does not get burned off...it is by product of soot burn...

Therefore logic would dictate if dpf has ash deposits accumulated then it would demand more frequent regens.

The qustion was ,,has anyone had dpf flash cleaned and have they noticed improvements in service interval length .. as one would assume dpf is now at full capacity and takes longer to fill up with soot and therefore less regen frequencies = less oil dilution.

mines passed twice and yes it will put out a bit of black smoke when you boot it also the exhaust is a lot louder you can hear it whistling when the turbo spins up and when the flap opens

yes I did long day!

Considered a rempa at DMS Southampton as they are down the road but after having the engine blow and speaking with the guys there even though i didnt get goodwill this time they said any chance of getting a deal would be out of the windows or any support from LR or any other warranty company is unlikely as its modifed!

I know some of the later oen can have the map original map reapplied should there be a prblem but that fine as long as you can do that before it gets looked at.

Also you would have to tell the nsurance as its mod and if you didnt and had a prang that wasnt a liitle car pak ding that required big money you can bet they will have an assessor to check this to avoid paying out or heaven forbid it was a person you would be facing legal! I know thats obviiuos but lots still dont tell the insurers when altered. Like a DPF or EGR removal fine I guess but the DVLA would need to know as the car is nolonger Euro 5/6 spec so would be taxed higher and suffer the emissions charges that I can see popping up all over.

It might be that the insurer is fine with it but the DLVA will need to know and then there is resale value.

It's a great idea if all above board, but should there be any problems with the engine or gearbox most warranty companies would reject it saying its been modded away from its intended spec so wont pay, not sure hwo they would no in certain occasions but if they can get out of it they will.

Fitting a dashcam actually lowered my insurance by £65 so it would be interesting to see how much remapping would cost extra.

If you dont mind paying out for a new engine if it were to blow 3.0SDV6 mainly then I'd go for it and save money on the warranty cost each year frst year would pay for the remap and the subsequnet years go into an engine fund pot just incase!

I'm bittered by the whole engine failure crankshaft issue but the hassle and costs Id just be wary of a quick mod that coudl end up costing alot more should something happen If a jobs worth doing, get a someone who knows what they are doing to do it!

RRS Autobiography Indus
RR P38 HSE V8
RRS Supercharged Santorini
AMG CLK Rear Tyre Shredder

I have had many cars remapped by Celtic Tuning at Newquay.
BMW 530
BMW 535
BMW X5
Freelander 2
RR Evoque
and recently my RR Sport.

I have nothing but good thoughts about the results.
My RRS has been upped to 330 BHP
Performance is now like a V8
Consumption is about 10% better

The cost was £250 and the process took about an hour.
