Hi All, I'm after a little help with my Mk2 2007 Leon TDI. There is an power/acceleration issue that's got progressively worse. I've had mechanics look at it and its been plugged into diagnostic equipment but nothing shows up. The issue is with pulling away when the car is cold, as soon as the engine starts to load up the power just dies and it returns to idle, for the first 10 seconds or so you can pump the accelerator and it wont rev, it takes dropping a gear to get the engine to rev or completely stop, and then it will start to rev again. Its bad on any sort of hill start when cold to, it will start to pull then just die and return to idle. I've had a new turbo fitted about 5000 miles ago so its not that (or hopefully) when its warmed up it pulls like a train with plenty of power and the issue seems to disappear. Do you have any Ideas what could be causing it? The car has been well looked after and just had a big service recently where the glow plugs were all replaced, its currently on 190K but is has been well looked after. Also when its cold it can have a lumpy idle at times when its stationary. Does anyone have any ideas what it could be?
