Hi guys on the way to work thismorning had a warning light come up on the I drive saying there was a problem with the dpf and the power may be restricted just wondering if anyone else has had this message come up and how much it will cost to get fixed. Really gutted with it being christmas and just paying out £1000 last weekend on a set of new alloys and 2 front tyres because the car failed on a cracked alloy arghh

[parapaul]

If it needs replacement, worst case scenario, its around £1500

First thing I'd try would be to get it on the motorway, sit at 70 in 4th gear (or whatever gear puts the revs around 3k) and stay there for 15 or 20 minutes. That will give the regen cycle a chance to start if its going to - and if it doesn't then you haven't lost anything.

Makesure it has plenty diesel in it too as it burns extra whilst doing a regen!

[briers]

Definitely

Get it on the m-way and monitor the coolant temp : http://e90.wetpaint.com/page/BC+hidd...us/revision/37

I would sit in the highest gear, i think 4th would be too lighter load on the engine to create enough heat to start a re-gen. Make sure you have a full tank of diesel as a re-gen won't happen on a low tank.

Needs to be around 1.8k RPM. Perhaps put the car under load, find a long steep hill and go up it at low RPM in manual, around 1.5k and accelerate up. Watch the temp rise, find a m-way or dual carriageway and see if it forces a re-gen?

Have you been doing lots of short journeys recently?

If regeneration conditions are met, the regeneration should start itself. If it is failing to start, something is not right, could simply be it is not getting warm enough (75-degrees) to start the regen'. Runs too short, or coolant temperature compromised with faulty thermostat(s).

When it does, certainly give the car a chance to complete the process. When mine goes in to regen' mode it normally takes about 10 miles through the Glen before I sense it is complete. Backed this up with watching the temperature as well, will increase to mid 90s, then start dropping back after about 8 miles. It will also let the car drop into 6th gear, if I'm travelling about 60mph.

With an auto you know it is initiating a regen', as the gears hold higher revs, plus the fuel consumption goes up. I'd guess at about 10mpg less, for about five to eight miles.

I pitty the not so into car people who buy diseasels and have no idea what a DPF is nor that it needs to re-gen...

If it were me, i'd remove it and have the function turned off on the ECU, Especially if it were to knacker up and needed a new one, think how many people replace them at ££££'s when they can just be removed. such a stupid expensive device.

[buckethead]

it will take more the usual 15-20 mins motorway drive to clear this you need to go on at least a 1 hour trip..
then a 15-20 min trip at motorway speeds every 2 weeks

if your using your car on a clear motorway every week ignore the above

[Team Green2]

Cheers for the replys, I know how a dpf works and I went on a 70 mile round trip last week so I am surprised that this has come up. Just to clarify does any one know what actualy determines when the car goes into regen. Had a bit of luck, my local garage said that they will take a look at it and try and force it into regen mode at the garage foc. If this doesn't work I will definatly be going down the route of a dpf removal and then mapping the Ecu for it. Thanks again guys will keep you posted

[Ryan87]

I've had the exact same thing on Tuesday crop up.

Got the car booked in for next Friday as thats the soonest they can do it.

Is yours on permanantely as mine has been coming & going?

[Team Green2]

Yeah mine only comes on when the car starts to warm up it doesn't come on straight away. I have got a quarter of a tank of diesle so I'm going to fill it up tomorro and take it on a long drive and see what happens. Will let you know how I get on.

[parapaul]

Any joy?

As of Jan next yr (2012), removing a DPF will result in a MOT failure come test time.

[Team Green2]

Well I filled the car up and took it out for a drive about 50miles along the m4 and back. But to no joy I have been told that I need to reset the error message first then take it for a drive but with all garages closed I have been trying to find some one with an obd 2 so I can reset the codes and see if that works

Isn't this dependant on whether the proposed legislation is retrogradeable? It isn't normally, which taking the text I read would suggest only vehicles registered on or after 1st Jan 2012 would be effected.

Cheers guys took the car to my local Indy and he managed to reset the code I then took the car out for a 30 mile blast and the warning light hasn't come back on touch wood but I will let you all know how it goes.

All this DPF chat is getting me worried. We pretty much only do short trips in the 330d and I can't say I've ever noticed a Regen happening... how obvious is it?

But maybe my driving style means it gets hot quite quickly? I used to have a Leon FR TDI and the Seat forums were jam packed with stories of blocked DPFs (hardly see them on here) but yet I never had a problem with that car either.

[Mr Singh]

Think if this happened to me I'd look to do down the route of a DPF delete. Pro's and Con's of it, but seems those who have done it had no regrets.

I hear the 5er exhaust ticking quite a bit...assume that's when it's being doing a regen.

But never noticed a regen during driving in the 330d

a mate of mine had the light just come on for DPF, he took it to a specialist and had it cleaned out, fault codes erased and put back on, the difference in power is unbelievable and of course.... the light has gone off too!

think it cost approx 200 pounds which is better than the new filter replacement sting

[briers]

How many miles has it done op?

if poss would be handy to have te specialist's name thanks

With the DPF, as it ends towards its end of life cycle (some say 100k/120k) even if its re gened does the car lose power generally slightly?

Reason why I ask is because my car has done 100k miles and seems to be slight slugish lower down the rpm
