Software upgrade applied this morning at Lookers (Stortford). Excellent service from the team - in and out in less than 30 mins. Thumbs Up

Why don't you (the ones that have DPF problems) try to drive a turbo-diesel engine as a turbo-diesel engine is supposed to be driven? On boost, over 2000 RPM?
I bet that most of you are changing gears as soon as, or earlier, that engine RPM reach 2000. Right?
You talked about BMW cars... A BMW car it's a sport car and therefore the people who drive them drive in a sportier manner. Thus little problems with DPFs.
Below 2000 RPM the turbo isn't working as supposed to do (can't deliver the right pressure/air quantity) and the quantity of "black smoke" (unburnt fuel) is considerable. Therefore, a rapid build up of carbon inside DPF.
Don't drive it like a granny. Don't let the RPM fall below 2000 after a change up. Change gears when RPM goes over 2500. Even 3000. Be a little sportier.
Don't worry, the engines can handle it. And don't think about MPG.
What do you want? A DPF problem free car and a few MPG less or best MPG and weekly problems with DPF?


As I said - you are encouraged by the car to drive more economically (the dash indicator) tells you when to (optimially) change up.....

Obviously MPG is a consideration - afterall if I'd wanted a sportier car, I would have kept with the BMW and been red-lining all over the shop....

I will try changing my driving style over the next 1000 miles and see if this has any longer term benefit. Thumbs Up

In my manual variant, I change up at or before 2000rpm. This minimises turbo use. The low end torque is more than adequate for normal motoring in that range. Down hills, never coast in neutral/clutch in. I believe that the engine uses near zero fuel under engine braking conditions - select a suitable gear to get some engine braking at low rpm.
Using these and other basic techniques gets me 40mpg+ pretty much all the time.

Not sure how this approach transfers to autos...

Thanks for the reply James. I should maybe have mentioned that my Freely's DPF was replaced just before the warranty ran out (today) and is now 3 years old and ca. 54000km. Therefore in my case not on a new vehicle as DervFan.

Alex, yes you do or may have a good point there Question Although grey and old (so I'm told Laughing ) I at least, don't drive like a granny on short or off-road excurtions, but otherwise ca. 90% driving is on longer distances. Unfortunately, you are quite correct about the 2000 rpm remark and often when cruising in 6th gear or even 5th gear, often around that. Interesting that is reported that auto's have less problems than manuals and that possibly autos rev more than "us granny's" and therefore be the source of the problem. However the LR self cleaning system should, I would have thought, be able to cope with the build up of carbon and do its job "when needed" regardless of how often it is necessary.

As mentioned above, our Freely has only this year had problems and the first two+ years were DPF problem free. I rather think that there has been a failure in our DPF system caused by something other than driving technique, and that is why I still (at least now) consider YF's earlier comments concerning oil type and DPF, as valuable Thumbs Up . 2007 Freelander 2 HSE TD4 Manual with Premium Pack & Moonroof.

Cold start this afternoon brought a splutter and restart required with warnings.

I drive mostly motorways at 2000 rpm minimum Whistle where legally allowed Whistle So one would assume the DPF was in good environment!

If it is the DPF: warm the car to normal running tempature then drive at a contstant speed above 30 mph for between 20 and 30 mins for example on a motorway. Stop the motor and wait for it to cool (about 10-15 mins or so) and restart. Hopefully the warning has gone and you will get normal running again Thumbs Up - This is the normal DPF cleaning function described in the handbook page 117 except the last bit about turning off the engine, which is from personal experiance and advice given to me.

If this dosnt work, its a visit to the dealer. 2007 Freelander 2 HSE TD4 Manual with Premium Pack & Moonroof.

This is where you wonder if Land Rover is having a larf. I live in South-East London. The action described above (and in the handbook) would require me to go for a completely pointless entire day out in the country, use gallons of diesel and waste a day of my time. The same though would probably apply if I lived on a farm in the mountains. How can this possibly be touted as an environmental measure? I cannot legally drive above 30mph anywhere within a half hour's drive of my house, let alone do it for 20-30 minutes!

Maybe it is LR having a laugh, but may also be the Censored EU with all their laws and regulations. There must be thousands that are in the same situation as Past master who own a vehicle with a DPF and live in an urban situation. The whole point is that we do not need DPF's at all but are forced to have them. However if the problem is just attributed to LR and they don't soon get a fix for the DPF system, my guess is there are going to be plenty of unhappy chappies out there Evil or Very Mad .

I'm fixed for the time being, but I wonder for how long Whistle . 2007 Freelander 2 HSE TD4 Manual with Premium Pack & Moonroof.

No get an auto - doesn't seem to be a problem on the higher revving less environmentally freindly auto.

Spanking SD4 Auto delivered end Oct. One week later 'Reduced Engine Power'and no other info to suggest why.
Interesting to think at this point 'what if I wanted to fix this myself?' Why do we buy cars that can only be sorted by plugging into a box that the owners don't have? If the cars clever enough to tell the owner the engines having a day off it should be clever enough to tell the owner why.
Rang dealer, took round and plugged into his clandestine box of rubbish. 'Good news Sir, DPF, we've had a technical service bulletin on this one, our technician has clicked the mouse and its all sorted'.
What the man at the front meant to say was 'the software engineer and the mechanical engineer didn't test their systems enough before selling a hatload to the public so we keep exprimenting with different software until the problem goes away'.
Gets in the car yesterday, 'Reduced Engine Power' So its got to go back again. Have a guess what I'm thinking...

Hmm. What are they like off-road? Seriously, I would consider it, but like most Londoners I'd need a few hundred metres of cable to link it from whatever spot I can find to park, up to my power point to charge it. And of course the local yobs would love that. And that's not to mention the neighbour who would "accidentally" trip over the cable and sue me. Rolling with laughter
