Well done Stu! It's not a B-road job is it! I'm hitting the M1 tonight.

you may have to do a "midnight run" on M1 for here to be happy.

35 mins all in, 15/20 mins on A1/A1m, then 20ish on A61, absolutely horrible flogging the engine like that! But definitely not speed but revs required! Current: TDV8 (3.6) RRS HSE

Ok did mine tonight on an M1 run. Wasn't midnight though nino.

Set stopwatch as soon as I'm on the ramp then run at 2500-2800rpm with the cruise on 70mph

At 19mins the yellow warning went away.

From the very end (London end) I was precisely Junction 9 when it went. Had to get off at J10 though as just passing the j9 and just not enough time to peel left. Turned around and came back in 6th at 2100rpm for another 20mins. Not sure if that would kick in a second regeneration but thought I'd try it anyway.

Feels so wrong cruising at 2800rpm when it can do 70 at 1500rpm.

Done now it'll be interesting to see when it goes again. I do nearly all city work short runs so I am a heavy DPF user!

. Cheers, Greg

you don't have to rag the engine to get rid of the dpf warning, a steady 50mph for approx 20 mins will do it.....that worked for me... ... - .- -.

My turn of phrase maybe not the best Stan, but to me doing 2.5/3k revs is ragging the engine! In the 4.4. I was only doing 55/60 mph in lower gears. Very uncomfortable process Current: TDV8 (3.6) RRS HSE

thats why the second turbo gets gunked up with oil and hence the drain valve modification...

the 4.4 is such a lazy engine i doubt anyone really goes much over 1500rpm... ... - .- -.

I think the handbook says that a period of driving at about 55 - 60 is the way to clean the DPF, rather than holding the revs high. I have oil seepage from one of my turbos, but no smoke, presumably because on Scottish A roads one has opportunities to get revs above 2,500 when overtaking after having been stuck behind slow moving traffic. Only Range Rovers since 1988

I have sent a PM to the LR crc account asking for the technical support department to confirm the best way to regen the DPF.
So we will all see what they recommend. G reg 2.5VM Vogue Portofino red 1991- 1999

This is what the owners manual says:

DIESEL PARTICULATE FILTER
REGENERATION
The DPF is part of the exhaust system. It removes most of the harmful particles from the exhaust emissions and stores them until they are burnt away. Occasionally the DPF requires a regeneration process to clean itself. When regeneration is required a DPF message will be displayed on the message centre.
Note: While carrying out the DPF regeneration procedure, observe all relevant speed limits, laws and regulations.
1. Drive the vehicle until the engine reaches normal operating temperature. Do not leave the engine idling to achieve operating temperature.
2. Drive the vehicle for a further twenty minutes, keeping the road speed above 80km/h (50mph).
3. If successful, the message will extinguish. If not, repeat the procedure.
Note: If after three attempts to achieve regeneration, the message does not extinguish, contact your Land Rover Dealer/Authorised Repairer.
If the message, DPF FULL is displayed in the message centre, contact your Land Rover Dealer/Authorised Repairer as soon as possible.
The regeneration procedure produces very high temperatures from the exhaust system. Do not park the vehicle over combustible materials. Cheers, Greg

so my DPF light came on again - it's only been 6 weeks (see above) since last DPF blast....

But I screwed it up; I've got a bit of a drive to get to a 50limit road let alone 70 so I thought if I hold the revs up over 2000rpm can't I just do it at 40mph? Maybe I don't need to get it up to 50....

This lack of speed threw up a red DPF warning within 8 mins.

Now I've got to take to dealer.

I guess because it needs airflow under the body from a safety POV.

I also read this which was not written about RR's more general DPF chat: DPF is cleaned by putting unburnt fuel through it which then combusts inside the DPF and burns off the carbon deposits. . i didn't know fuel was fed in then basically ignited in the dpf. Another post mentioned a dpf warning coming on too regularly and after 6 dealer visits s pipe was found to be blocked..

Quote:

the dealer essentially refused to replace the DPF, first they said it was the way I was driving it, even he garage owner took me out to show me how to clear it. Turns out they replaced a clogged pipe? not sure what it was, but it was replaced and then they send the DPF off to be cleaned.

what does a RED DPF actually signify?

when I was having mine on a couple of weeks ago, I chose higher revs over speed the first time and it took longer to reset!

the second time it happened I drove normallyish ...kept it in sport mode and drove in 6 gear on A1(M) for less than 10 mins at no more that 60 mph really and it went out and hasn't been on since.

is it totally necessary to go to the dealers just because it is red? Current: TDV8 (3.6) RRS HSE

to clarify, you do not have to drive in sport mode or high revs to regenerate the dpf, just a steady drive at 50mph for approx 20 minutes... ... - .- -.

That's what although badly I was trying to say Stan. I just wanted to keep the revs up a bit as I only have about 15 mns on the motorway then A roads. Easier to do it on the motorway. Current: TDV8 (3.6) RRS HSE
