Hi Guys,

Last week I had "PARTICLE FILTER FAILURE" diplayed on my dash. I've studied what this part is, taken the car for a long spin to unclog - no change. A couple of guys have removed it and attemtped to clean and reuse it successfully.

The car runs fine '06 E60 530d - anyone have this problem before - does my system have to be just reset? My car is out of warranty.

 

Your particle filter is probably clogged or almost clogged. Go to dealer or similar and get the error memory read. If there's an error about the clogged DPF, you can try the same that I did --> washing the DPF. Here's my DIY.

Thanks for the reply. Have you had any problems with your dpf since you washed it? How many miles are on your current dpf?

 

Well it's been only week since I washed it and about 200kms, but there haven't been any problems. The car pulls stronger than ever.

My DPF was so clogged, that even a "forced" regeneration didn't start after a dealer visit. After a wash, the regeneration started immediately when the coolant temp got warm enough!

Since you have a 2006 car, I think your DPF locates right after the turbo and it's integrated in the same can with the catalytic converter. It is a bit trickier to remove than mine, but still doable.

Brought the monster to the dealer - they forced a regeneration and told me to drive it for 25 miles before parking it up - It worked - and mpg has improved by about 15%. Cost me ?85. Supposedly the dpf lasts 180,000 miles. I'll clean it out before and if I reach this mileage. IT'S GREAT TO HAVE MY MACHINE AT 100%

 

Just to keep you all posted - The filter failure came back - I updated the idrive software and reprogrammed the car - Gone for good now. I hope. I recommend updating the idrive software to anyone who has a 2007 model or older - its so quicker and mine got a silver display colour scheme to suit my car interior and exterior.

I hope it's not a sin to love a car!
