According to a RealOEM, your car has a combined catalytic converter/diesel particulate filter, unfortunately. It is more laborious to remove/reinstall than the older one, which locates under the car easily accessible, but yours locates right behind the turbo. So, when it comes to a point that the tin can has to be removed/changed/washed/modified what so ever, it will be more time consuming. However, the DPF part of it can be drilled through to get some more lifetime.

It would be a good thing if your mechanic could send the "forced regeneration" command to ECU with his diagnosing software. Even if he could, it can be that the filter is too clogged and the regeneration won't start. Also, the engine coolant temps have to still climb up over 75°C and the exhaust gases temperature have to go over 240°C, even with the forced regeneration.

I suggest you use the "hidden menu" in the instrument cluster to monitor your coolant temps. Here's a guide to open and use that menu: http://www.scoopz.com/m5board/E60_Hi...structions.pdf

Hi All

Error gone Thank god. Brought to my local mechanic (Dave Breach motors) and he used Auto Logic to run a series of test on the car, excuse my lack of knowlege here but when he plugged in to the car, the car seemed to run a series of high rev tests itself and my problem was a sensor, all cleard up any my car is running superbly .

Thanks for the help all.

Not such good news for me unfortunately: DPF is shot; forced regeneration did not work... :thumbsdown:

Will need to clean or replace... Stealer quoted me 1.680? ex VAT...

 

And you are sure that coolant temps rise high enough and you have enough fuel in tank (10l if I remember correctly)?
If you have the separate dpf in the middle of the exhaust piping, under the car, you definitely want to try washing before buying a new one. It is an easy job once you get the dpf removed.

And even if you have the combined dpf/catalysator, I would still recommend it. It is just a bit more difficult remove/reinstall.

Final diagnosis: main turbo failure caused DPF to be blocked beyond any regeneration... Both parts need replacing at the very "interesting" cost of 4.500?

In Holland they say BMW means "Blijf Maar Werken" (Keep On Working) - as in to pay the repair bills... :thumbsdown:
