2008 A4 2.0 tdi convertible. low fuel, power loss, now wont start.

Hi all, my name is carl. this is my first post and im desperately looking for advice.

I have an 08 Audi A4 2.0 tdi convertible with only 24,000 miles on the clock.I ran the tank quite low on saturday down to 25 miles remaining on the range calculator.
the following day as i first drove it i noticed a lack of power. i only got 2 minutes around the corner when the car stalled and wouldnt start.
other than low fuel there were no other warning lights on the dash.
i put around 12 litres of diesel in it and tried to start it but it wouldnt go.
The RAC came and tried to blank off the EGR valve but this didnt do much.
today they returned with a new EGR valve but this still didnt fix the fault.
there were no fault codes showing on their diagnostic machine.
they now say it might be the dpf !!
Im wondering how it can be the dpf when there are no fault codes and no warning lights on the dash and the mileage is quite low?
Could it be that my car has ran out of fuel and now has air in the fuel system? I would of thought the RAC would have thought of this first and tried to bleed the system or something.
Currently my only option is to try a local independent specialist and hope they can diagnose the fault before i spend a small fortune on parts i may not need.
Any help or advice would much appreciated.
Many thanks in advance.

Turned out to be a blocked dpf. Bypass and remap being done as we speak.

let us know how you get on with the remap as I'm thinking about getting mine mapped too

before bypassing the dpf and getting it mapped out, i would have read up on the law and how removal of the dpf will result in an mot fail.

hope they gutted the dpf and put it back or you will be out of pocket a major amount next mot mate new rules state must be present if it was when new look forward to that

[ray38carp]

I've heard they will still pass an MOT with it removed?

[ray38carp]

Hmmm! Yep I stand corrected, just read an article that they are about to change the DPF laws for an MOT in February 2014,,, That's put a spanner in the works as was thinking of getting the DPF removed myself

[zollaf]

leave it in place and remove the guts, so it looks like its still there and they will probably introduce a different emissions testing machine that will tell its not there, then you don't meet the relevant euro emissions your car was built to, you then fail the mot.

best to find a 07 car that doesnt have a dpf and map that to stay within the law
