You might as well wait for it to play up and then remove it. Chances are that you will never need to touch it.

Yes I would probably wait until it need replacing and then remove but I would interested to know if it could damage anything else when it went.

Land Rover have recently had to update the Defender model which now comes with a DPF. They carry out research when developing it and monitored how they are used (eon vehicles etc) - a lot of short journeys. They came to the conclusion that fitting the DPF under the vehicle (as normally positioned) would not work as they would not warm up quick enough and hence clog up. They are therefore fitting them in the engine bay in place of the down pipe. The result is that the dpf gets up to working temperature much more quickly and they are confident that they will not clog

Skoda's Superb had the same issue years back. Didn't get up to temperature as it was too far from the engine in such a big car- and was refitted nearer the engine to make it work better.

after a bit of heated discussion with sales manager and been told of for wasting their time not buying he even did not want to return deposit, but anyways probally better off found out it was stage 5 with DPF.

Sounds like a good garage to deal with. Great customer service skills, they could have atleast tried to sell you something that would have been suitable for your needs.

Unlikely because the engine will go into limp mode to protect itself as soon as the terminally blocked filter is detected.

Like they used to do with the cats on the petrol V8's... for the same reason.

The cost of replacing the DPF with a straight-through pipe + blanking-off EGR + remap of ECU (although most cars don't need this) is soon recouped in the higher fuel efficiency of the vehicle.

I work with a chap who drives a TD5 Discovery. With the mods mentioned above, he has gained another 11 mpg.

The only issue is if you need to travel through the London smog zone. Even then, to remain compliant all you do is have a twin-mapped ECU (quite common on tricked-up motors). Then drop your DPF back in place before you go for the mot (no need to do the EGR as the smoke test is done with engine at normal running temperature in which case the EGR will have shut-off anyway).
