Hi All
Does anyone know what to do when the I-drive service message comes up with regards to the Diesel particulate filter?
I have a 525d from Nov-05. I know it has this device as I never see black smoke from the exhaust. In addition I hear it being cleaned occassionally (exhaust sounds a bit louder then).
So I doubt the I-drive service message means replacing it, right? As it's not a simple filter. So what am I supposed to do with this message? Simply reset it to 2 years from now and ignore it?
Thanks for any help

What does iDrive say (Service Indicator) about when your DPF needs to be replaced? 
How many kilometers on the car?

When BMW say service it they mean replace it - and it's expensive.
When the time comes for mine I'll be taking it out, giving it a good clean with whatever will clean it and putting it back.

what would happen if I just reset I drive and don't replace it?
Also is there a work instruction somewhere on how to clean it as I don't feel like spending a uge amount of money on that if the filter still seems to be working correctly when that time comes....

Just done a bit of research.
Basically the regen will burn off any soot but gradually ash will build up. The ash comes from engine oil that gets burnt.
If the DPF gets clogged the car won't be able to run properly.
Because DPF's are new you generally seem to have to by genuine very expensive replacements (just like when catalytic converters were new). Hopefully that will change over time.
For commercial vehicles the problem is just starting to crop up and there are a few companies that can clean the filters. All they do is put pulses of compressed air back through them and sometimes a good bake.
If I was you I'd try removing it, cleaning the hell out of it with compressed air then reset the iDrive and see what happens..... and keep us posted!

Thanks for the info
Isn't removing it going to be difficult?
Just like a catalytic converter I assume the DPF is part of the exhaust system? So like removing the muffler I'd need a torch?

In theory it's a service item that just unbolts, but being part of the exhaust I suspect it might be a bit stubborn....
