Engine: D5: Soot Filter driving me crazy...HELP !

[tingy]

high rpm being what 3-4k cuz most legal moterway driving in 6th wont see it above 2.5k or would 2.5k be enough???

[Clan]

well you could leave it in 3rd or 4th ! if you drive it gently it wont often go over 2000 rpm so anything over 3000 i would say ...

that is asuming your running manual or geartronic what about auto?

mind you would be a good excuse for getting pulled doing 120 sorry officer i had to clean my soot filter

geartronic is auto , the same box with some manual intervention but never woth the £1200 for a lever and software tweek . you can do almost the same with the L position ..

Well I drove about 20 mins down the M6 and then the same back up again and it doesn't seem to have had any effect at all, I still have the message and after I had stppped briefly at a services on the way back up it seems to have lost power - it was still driving and was able to reach motorway speeds but there was definitely nowhere near as much acceleration as there should have been. I've now got the Engine System Service message as well.

I've done approximately 800 miles of motorway driving this week and am confused as to why it's suddenly decided to do it.

It's going to completely screw up my weekend, in which I already didn't have enough time to get everything done

thanks spmurugs for the link to this.

I believe none of the above posters lost 100% power (and unable to restart engine) so will look further, and advise when the "fix" is known.

thanks, David

I can't help wondering what you do if you're over a hundred miles from a motorway and have mostly single track roads to get to one. Like when I'm on holiday.

Dosn't sound like cars with a filter are suitable for all round use!

Shouldn't be that difficult to keep the revs above 2K.
OK, it won't get as hot as quickly in lower gears because the engine's not having to work hard at lower mph - but a heavy right foot from a standing start up to high revs in 2nd on a cyclic basis should achieve the requisite temp.

run it for at least 20 mins in a lower manually selected gear at 3500 revs or above every 300 miles or so. The AA mechanics are having this problem with all makes of car the Dpf system is useless.

Does anyone know if using low soot fuels like shell vpower and bp ultimate help in this matter ?

That's never going to be my style I'm afraid.

What about if you're on a motorway and there's and jam and you have to spend 2 hours stuck in traffic. It's happened to me more than once. I spent over 2 hours on the Chiswick roundabout gridlocked some years ago. Add limp mode and a visit to a dealer to fix it. It's a recipe for going postal methinks.
