I couldn't buy a 20L drum of LR's recommended non-DPF oil. I'd rather use non-DPF oil as I understand that the DPF version is a lubrication compromise.Quote:

A DPF regen in traffic could be a nightmare and downright dangerous for an inexperienced driver.
Another Graeme
I don't know whether its a passive or active record but there is a DPF-fitted parameter in the CCF.
What is dangerous about a regen? The driver doesn't even know anything is happening. I have had a DPF on my VW Multivan for 5 years without any driveability problems for anyone. The only problem is that I have been told it is cracked and I need to fork out $2500 for a new one at only 130,000km. Since there are no error messages or power problems I won't be doing that! The other problem is that the fuel consumption is much worse than the non DPF older model VW's.Quote:

I have only had it since December so I might be missing something but so far it is fantastic.
Mine is a October 2009 build and definately doesn't have a DPF.Quote:

IIRC the VIN also indicates if it has a DPF by virtue of the engine configuration code.Quote:

Thanks for that Graeme. Mine doesn't have a DPF on that basis and I can see the support point for the DPF with nothing attached to it.Quote:

I found them good. They attended to the problem immediately the morning the vehicle was delivered to them. The LD4 was looked after and retuned in good condition.
I have an Aug 2009 build D4 SE with a DPF. I've owned it since new and the warning light has come on only twice and I've been stuck in nose to tail traffic jams on far too many occasions.Quote:

As soon as the car gets a chance to drive normally, the light goes out within minutes.
Back on topic...
After a brief "restricted performance" yesterday morning which was overcome on the 2nd restart, today the D4 spat the dummy totally. It had to keep doing its duties of fetching a few large square hay bales but ascending slight inclines at less than 60 kph was tediously slow. I'm sure much more power could be allowed yet still be well below any condition that might cause engine damage, especially considering that the engine seems to be limited to 3000 rpm. Clearing the faults with the engine stopped only lasted until quite minor throttle use but clearing them again with the engine running then immediately getting the revs up high a few times has so far kept the faults away. The 2nd turbo is getting replaced next week due to the on-going smoke screen after prolonged cruising then opening the throttle significantly, so whatever mechanism (air valve, turbo solenoid, ??) has become sticky needs to get replaced too.
