Hi, my old L322 06 td6 vogue se a. Is playing up. Went it would not rev over 2500 revs, then the fuel pump in the tank went, replaced the pump and gave her a new fuel filter, back running, revs fine in Park, but when in drive limits to 2500 reves, but can clear it's self sometimes (not that often to be honest). Hopefully this is a stock fault and some one will nail it. Had a few classics, but my first L322, been trouble free for about 4000 miles. The code reader I have does not recognise the car, but car shows no code's or warning lights
Thanks to all in anticipation
Took it for a run, when warm won't rev over 2500 in drive or park, can be annoying when you get past by a push bike

If you've replaced the in tank fuel pump, did it make any difference?
I would be looking at the secondary in-line fuel pump next which is located on the underside, Infront of the rear N/S wheel by the sill (there is a little hatch to access it which is held on with a 10mm bolt IIRC)

The secondary pumps are very common to fail on the TD6.
