The car :
Audi A6 3.0 TDi Auto Quattro 2009 facelift
CDYA engine code
The problem :
Hold a constant 2/3 's throttle - run through the gears without deviation - 1,2,3,4 all pull strong, smoothly drops into 5th and goes flat, still accelerates, then pulls strongly again in 6th
The fuel econ is also poor, 25mpg to the tank (long range 80L tank) - mpg measure correctly from fill up to fill up.
The parts it's had recently :
Complete fuel system : hpfp, lpfp, regulator, injectors x6, rails x2, link pipes, vacuum pipes, filter, filter housing, relays, entire wiring and ECU check, tank swabbed out, front to rear fuel lines flushed out, software update, adaption values reset (fully adapted again now)
Complete auto box rebuild - new oil, new transfer box oil, new rear diff oil
Turbo inlet seal replaced
Swirl flap updated and new rods fitted (both banks) (full adaption since this also)
The car has no fault codes sorted, non pending
All the work work has been carried out at main dealer Audi
Anyone got any ideas ..... We are stumped .....
