Audi a6 3.0 TDI Fuel problem and DPF warning
Hi, I try to get help here! Im from sweden but have got no info here who can say the correct sollution without change every part of the engine.. Hope english is ok 
I ran on cruise control and suddenly the glow plug light came on and started blinking , i lost power and if i give throttle the engine "pulsating"
if restart car, the light come off until i give extra thottle then it came back.
I drove like this for 1 week and it got worse and worse, more pulsating engine.
I changed the Fuel pressure sensor on the fuel rail, left side. and fuel filter.
No change. I drove it to the mechanic (30 km) Now the particle filter lamp started to warn. I continue and mechanic can only see fuel pressure problem in computer, nothing else. So i got not so much help there.
Im on the way home and then the car start with heavy pulsating 10 seconds then dies. I got to go back home with the towing rope.
At home it can start some seconds and then die.
I checked fuel pressure "fuel tank low pressure pump" and its 4 bar i guess thats ok.
I got error codes :
P1063 Fuelpressure the highest value is reached
P1063 Fuelpressure the lowest value is reached
P1063 Fuelpressure short circuit to plus
P1573 Valve left enginemount cut down
P0501 vechicle speed signal not correct
I have swedish OBD program so i tried to translate as good as i can..
If i delete codes and drive, then P1063 is the one that always come back, the other 2 can stay away for longer time.
I guess its fuel problem that now maybe clugged the particle filter?? Or can it be only the particle filte?
If anyone have idea what i should do please help me!!
Thanks
/Rick

@a3Autofahrer I stand corrected.
First, because of my 'great' english skills I had to check the meaning of that phrase using google. And now I got it. And I hope I will keep it in my mind.
Never mind. I did read a lot of technical information about that nice running V6 common rail engine. Additionally I had to fix some particulate filter issues.

Haha.. don't you worry about your English... it's better than of many native English speakers 
We Germans are too critical/self-conscious about it. Where we would criticise a foreign german-speaking fellow, the other way around it would be no worries.
And as a little extra, before we return back to topic - I found this page very helpful over the years: www.leo.org

Haha, den rahme ich mir ein. Ich stimme Dir aber zu, dass sich andere überhaupt keine Platte machen, was sie sagen und auch wie sie es sagen.
Cheers
btw, leo.org ist super.
just to clearify, now i have a new belt and it runs great again!!
hallo
