Golf Mk6 TDI brief loss of power downhill
Discussion
I've had a manual TDI 140 for a couple of months now, and while generally very pleased with it, I've noticed an intermittent brief loss of power, mainly in 4th gear lowish revs, when the road dips downhill. It lasts maybe a second or so, so is not dangerous, just annoying. I've searched google and read of a few others having similar problems, but all seem to have been told by dealers that there is nothing fundamentally wrong. Has anyone here experienced this and had a fix?

we have had similar issues with our tdi sport 140.cruisning along, back off teh throttle and feather it lightly and it will sometimes hiccup for a second or so and then return to normal.
VW ran a diagnostic but there were no issues, or warnings in the logs
interesting enough, once, we lost all power. couldnt accelerate, only maintain speed. dropping down the gears, was the same.
Pulled into services, stopped the car, switched off engine, restarted it ... no problem .. wheelspan under hard acceleration all the way back to motorway cruising speeds. has occured 4 more times that I can recall. VW cannot find any problems
