Are the injectors all tightened in enough/clean at the base?  Mine was pretty slow when I had a slight leak on two cylinders.  Some soapy water at idle might show if there are any leaks around the injectors or the glow plugs.
Waiting for a bigger better diesel to come along.

Might be because your avatar is so huge...   :P


Really though... sounds like air is getting sucked into the fuel lines before the IP somewhere or you have a blockage / clog.

If you left it sit for a while does it also take some cranking to get it going again? In otherwords has fuel drained back to the tank?

I had almost the exact same problem on my 03 TDI a couple years back....

Went crazy all day Mity-Vac'ing all the lines and checking injectors only to find a seam had failed on the fuel filter after 8000 miles. It was a small hair line leak at the seam but, was enough to be  problem.

I wants to understand well, if i translated correctly, that gives me the effect of a timing too retard with a came plate not enough aggressive.

Here i see some TDI with AAZ pumps, and it is the same thing which occurs.

Well i dont think it is puling in air to the diesel system , car got std turbo with no pipe going to the wast gate so runs max boost 22psi , and the car only goes down 3 cilenders in 1and 2 gear under hard throtel and the rest of the time ok , going to put .216 nozzels  and a biger turbo in the next few months 8)

try a lift pump back at the tank
 i mean a pump(at the tank) to supply fuel to the IP
my car used to"lay down" in the higher gears before i used a supply pump to bring fuel to the front of the car
Throttle cables ftw
