What does RealOEM say when you enter your VIN and look at the exhaust section?

When I select the DPF parts, it says "No parts found matching your car." So no DPF was factory fitted and the retro-fitted DPF is not fitted either.

I think the factory-fitted DPF is monitored. The retro-fitted DPF is not.

yup LX10326 and search shows this...so not sure if fitted still

Searching for this Catalyser/Diesel particulate filter gave me this in long list:
18_0716: Retrofit diesl particle fltr unregulated
18100422102: Installation kit, open system, DPF

Retrofit particle filter E53-M57 EU3 1 18100418189 EBA 0035951, EBA 0428574
only in conjunction with
-- Installation kit, open system, DPF E53 - M57 EURO3 1 18100422102

If you have vacuum actuated turbo (instead of electric servo actuation) and no throttle valve before EGR it's EU3 variant without DPF. Also injector part numbers are different on these EU3/EU4 versions.

@Clavurion and Wpoll sorry to bring this up, but is bugging me when i enter realoem and search for dpf i get reference to retrofit options as per image, so i take my e53 is EU3 and not EU4 correct?, has no dpf...? this allllll goes back to the oil thread and using the correct oil to keep the dpf clean so to speak...(that hopefully dont have)

With the electric VGT operation, a throttle valve, DPF with monitoring, swirl flaps etc. I guess the EU4 3.0d e53 is a very different beast!

Electric EGR operation too? Not sure I've seen that on the e53 - only the later e70 and some earlier sedans using the M57TU/TU2.

Well actually not that much different.

The very same vacuum operated EGR valve. (Of course the housing is a bit different because the throttle valve is connected to EGR valve.) AFAIK E70 3.5d (US variant) is the only M57 engine with electric EGR valve. The EGR system on this is much more complex with separate low and high pressure EGR.
