bacillus, I will do the adaptation asap, thanks. The mod for the floating mechanism consists of modifying the shape of the metal wire so that the floater comes closer to the pump's body and further away from the wall...you can see the pics on my install here > http://www.mk5golfgti.co.uk/forum/index.php/topic,12484.225.html
Teutonic, the fuel filter is 6bar if I recall correctly !

Have you actually changed the filter? The filter itself has the pressure limiting valve for the low pressure side - and that may be foobar'd. If your ECU requests 6bar, the controller on your low pressure lift pump may well be delivering 6bar, but the pressure limiting valve in the filter might be knackered (say only allowing 3bar), and and sending excess pressure (and therefore volume) back to the tank.
A relatively simple job to replace, and even if it doesn't fix the prob of low pressure, at least you'll hopefully be getting a better fuel flow. :happy2:

Replaced the filter 1 year ago and done like 3-4000miles since then. Should I replace it again wirh an identical one or can that pressure limiting valve be removed frim it ?

Several people have fallen foul of incorrect fuel winter.

The TFSI's come with a 6.4bar filter IIRC. The latest part number is 6.6 bar :happy2:
