Anyone with access to Peugeot Service Box could check the exact equipment the vehicle left the factory with using your VIN.

You could get a print out of the relevant section of the vehicle equipment as it will say something like WITHOUT FAP or FAP ABSENT - something along those lines.

The 607 is a bigger and posher car, but my 207SW was built in early 2008 and has no DPF, tho the version with higher output would have. So perhaps a 2006 607 is also at a turnover point ?

The car's VIN should identify what engine (and DPF) your car has, to any person able to interpret the necessary 6 characters (4 to 9). In fact the car's handbook would tell you, from the specifications.

Post the last 8 digits of the VIN and I'll check.

He said he will ask one of his mechanical to look under the fuel tank to see if there is elyon tank (I don't know what this is) he confirmed this car doesn't have DPF.

The Eolys tank was fitted to most French-made cars that had DPFs, Eolys is a fluid catalyst which helps to promote burning-off of the soot in the DPF. So those cars with DPFs had a separate Eolys tank and injector system.

But as yours was made three years before DPFs became mandatory on diesels sold in the UK, it may well not have had one from the factory.
