DPF forced regen/cleaning in Aberdeen?

[8bit]

Got the dreaded DPF warning on my wife's Jag XF this afternoon, took it for a run this evening but it hasn't cleared. Looks like I need a "forced regen" done. Anyone got any recommendations of anywhere in/around Aberdeen for this?

There is probably a reason why it won't regen, you need to look into that first rather than just forcing it to regen.

Thanks, will look them up.

I guess I don't know that it isn't - there's no light on the dash to say when it's doing a regeneration and the handbook is pretty vague about it. We do a reasonable amount of short trips but we do also do longer/higher speed runs probably once a fortnight or so. I'm not clear on what it's doing a regen, is it fully clearing out the DPF when it does etc. I did check it for fault codes this morning, the only thing I found was P2463, basically saying the DPF is full, which I already know. Nothing to suggest anything else is at fault.

This is the first diesel we've had with a DPF though so I'm not that clued up on them. Anything else we should be looking at?

It’s rare to find a dpf full, we usually find something is stopping it, on mazdas it’s as simple as an oil service light not being reset, others egr or glow plugs can cause it, on older fords fuel level.

I’d clear the codes and give it a run, if not try and get the soot content rrad. We had a freelander in recently with a full dpf that we did have to clean, that was caused by a split pipe on a pressure sensor and the electronic actuator on the turbo playing up.

Thanks for that, very helpful. I did get someone to try a forced regen yesterday, he said the readings were about 60g of soot. It did initially start to drop but then climbed back up so the system (a SnapOn diagnostic table thing) cancelled the operation. The only code as above was P2463, DPF Full. I guess if there is 60g or so of soot in the filter then clearing the code and taking it for a run won't help? I've also no idea how much soot is too much or what a "normal" reading should be but that sounds like a lot to me?

On the subject of other causes, I spoke to a fellow Jag owner with the same engine (3.0 V6 twin turbo diesel) in his XJ, he had a very similar issue recently. He took his to a Jag specialist in Glasgow, unfortunately a 5 hour round trip from us or I'd do the same. In his case it turned out to be a faulty throttle body that was preventing the car from being able to regen normally. I'll try and speak to that garage and see how they identified that cause and try and check that out on our car.
