Particle Filter

Hi All

The particle filter warning has appeared on my 335d (07 Model with 60k). The power has dramatically reduced too which is rather annoying.

Just wondering if there was any cheaper option other than to part with 2k at the dealers..?

Thanks

Had the same problem, removed the DPF the EGR and fitted an Ecotune down pipe and remap!

Thanks...

Can I ask how much that set you back where you got this done?

Before you go spending loads of money (like I did!) If you haven't already I'd check the 'secret' menu for what coolant temp your running at, it probably hasn't done a regen because it's lower than the 75 minimum I've heard it needs.

If it's low then consider changing the EGR and maybe the main thermostat - which should then sort your problems.

If not then you have the choice to have the DPF removed gutted or replacement pipe fitted etc..

Thanks I will check that, the "coolant low" also appeared as well.

So I managed to access the "secret menu" and the coolant temperature is 97 C, does this mean that a regen is no good?

Was that stationary or driving? If driving it sounds like its doing a regen at that temperature

Have you checked DIS for any faults?

I have the same issue... Checked it and all 6 glow plugs are showing a fault. Chances of them all going at ye one time are slim... So changing the glow unit as a regen can only be done when all 6 are working and all fault codes cleared of the system.

Before you start spending a fortune, get it on the computer and check the codes.

In my case the unit only cost £80 so definitely worth trying..!!


Good luck... And let us know how you get on..!!

Dan-danGT - That was actually stationary but after a drive so engine was warm.

mammoo6 - Pardon my ignorance, by DIS do you mean plugging it into a computer?

Thanks

You need to maintain a constant speed and watch that temperature, mine was only hitting 80-82c while driving which is too low. Thermostat should open at 87c so you should see 90-92c if its working properly?

Yes you need to connect it to the computer via OBD Port

Even if you continue to try a Regeneration, it won't work as the fault is now on your cars computer and will need to be cleared before it will allow it to actually try again.

It's not difficult if you get all the correct bits and pieces, or most garages will be able to clear them for a small charge... But I got mines from www.bmtechnic.co.uk very easy to install, good price, and the guys there offer good support of you need a hand

Thank you all for your help...

So the running temp at constant speed varied from 80-97.

Then my mechanic suggested I take it for a blast on the motorway and try to hit and keep 4000 RPM... This was easier said than done but managed to hit it a few times and after about 15 mins the Particle Filter exclamation light disappeared and I have my power back....

Been a couple days and so far so good. Am driving up to goodison park tomorrow so a final 400 miles blast should hopefully sort this regen out (hopefully with my point still intact).

Thanks for all support

Contrary to what most people believe, the best way to regenerate a particle filter is to drive at a steady speed between 60 - 70mph with as little amount of throttle applied to hold that speed. Depending on how blocked the filter is this can take (usually) around 30 - 60 minutes.

However, as mentioned above certain fault codes need to be deleted to allow a successful regeneration.

Glad it unblocked for you on this occasion, try to ensure you complete the above drive cycle at least once every fortnight to stop it blocking again.

This isn't strictly true, from what ive noticed you want a fair amount of throttle load that will cause exhaust gas temperatures to increase,yes a steady throttle is better than town driving.
And the longest regen I have witnessed on my e90 is 13 mins

Chriz, have you monitored the exhaust gas temperature under both conditions?
Think you'd be surprised what happens to the exhaust temps under these driving profiles.

Generally regens can occur quite quickly, 13 minutes being just about as quick as it gets. However, when blocked and causing warning lights it can take several regenerations to get the back pressures within limits.

Nailing the throttle everywhere very rarely gets and keeps the exhaust gas temp up to the necessary 600 - 700 degrees and burns more fuel.
When the background info says it adjusts the fuelling to heat the exhaust, most people assume its adding fuel when in fact running leaner (light throttle) will increase exhaust temps more reliably.

Exactly! Constant driving speed is most successful at maintaining a high exhaust gas temperature for regeneration

Yes I have mine regens every 300-350 miles 95% of my driving is town and wheni I see a regen kick in I head for the motorway.
Sorry I was talking about a healthy dpf regen time depending on how clogged the dpf was I guess it would take some time as you mention to clear
