Strange revs on ignition start

Hi,

Recently when turning on ignition, the revs behave a little erratically. It then seems to follow that the car will drive without pushing on the acceleration pedal. I usually turn it off, wait a moment, then turn on again, and continue until it doesn't do it.

Any thoughts as to what would cause this?

Not sure if related but the yellow 'spring' light on dash takes a while to go off.

Here is a video on Vimeo of it: https://vimeo.com/104631321
Hopefully you can see and hear the issue.
 
i would say the glow plugs are not working correctly as the light is on a long time. cheers mike
 
I had something like this maybe twice not long after I bought my TDi. Was possibly in limp mode, and the ESP light would come on.

I also had the light come on when driving in straight lines at speed.

When replacing the front 'ditch-finder' tyres I realised they were different sizes, one side was a 50 profile and the other was a 55!!! Since changing I've had no issues.


Having just watched the video, missed it earlier, that's different from how mine was and like A2sumo says your glow plug light seems to be illuminated for far too long. A scan would be a good idea.
