Greg, I noticed that your RRS is 'Superchip enhanced'.
Was the vehicle smoking before the installation of the chip??
Cheers, Craig

						I have a DPF on my 3.0l D4 and it has regenerated a couple of times in the 2 years + that I've had the car.......no noticeable smoke or performance issues.
Light comes on in the dash with the warning notice and turns off after a few minutes of normal driving. Does register a fault code however, according to LR.
Cheers,
Kev.

There was a guy a while ago....many, many threads ago.....that had just had his new D4 HSE (3.0l) serviced. He was cursing all things LR, the D4 and the 3.0l engine. He couldn't turn the engine off.
I can't remember exactly but I think he'd had an oil level indicator issue after the service and then the 'runaway' problem. I don't think he ever came back on the forum and fully explained the outcome but the concensus was that LR had overfilled the engine and this had overpressurised and had blown a seal into one or both turbos, thus feeding the engine with it's own oil instead of diesel.

Hi
Sorry , I don't read all , but : what about EGR ?
No message on the dash ?.......
Marc.
Well, this will be interesting. Local LR dealer has had the car for three days now, it's due back today with replacement turbo. Fingers crossed everything's back to normal.

						I would be suspecting the chip.
Here's the deal. Diesel engines, particularly high performance ones run a maximum amount of fuel that can be burnt cleanly and safely with the air available. To increase the power (as chips or remaps do) the maximum fuelling is increased, this can result in smoke and exhaust temperatures that are dangerously hot for pistons and turbochargers. If the turbo boost pressure is raised at the same time then the exhaust is cooled back down to safe levels, but the loads on the turbochargers increase and they may now have to work outside safe limits of turbocharger rpm and pressure ratios.
Either way, your remap has made life a lot harder for your engine and turbochargers, not to mention the driveline which has to take the extra torque.
I suspect if the dealer finds out about the remap (quite easy for a clued up dealer, they simply read the ECU map and compare to what it should have) then you would be paying for this turbocharger yourself and any future problems related to the engine, turbochargers or driveline.
Good advice, thanks Dougal. Might be time to reverse the remap.
DPF (diesel particulate filter) I think.
In my very layman non tech speak this basically captures some of the heavy particles produced by burning diesel and filters them out of the exhaust.
Generally normal driving will allow these to be burnt off as the engine will operate at a high enough temperature for the filter to effectively clean, burn off these particles.
If for some reason you do not operate the vehicle in way that this occurs, i.e. very light right foot then the engine will run at a higher rpm for a period of time to generate the heat and burn this off.
In saying that I am sure that there would be warning all over the place advising you of this and from memory (reading my manual 3 years ago when my D3 was new) it would advise you to drive around at 2,500 or 3,000 rpm for 30 min or so to complete this.
Please note most of the above is based purely on my recollection with little to no technical expertise to back it up and could be 100% wrong. But I am sure DPF stand for Diesel particulate filter !!!
Sound like the turbo anyway so interested to hear how you get on with the new one, hopefully warranty is not an issue.
