Jerky accelerator

[VAG1]

The best way to describe this is 'kangarooing'. Coming on and off the accelerator causes the car to kangaroo.

The car is a 1.4 FSI Mk5 Golf, only fault code on the car is 19498 which is to do with the heater regulation (not listed on ross tech). That fault code has been found on a few engines the same code as mine on uk-mkivs.

Not sure if the kangarooing and the fault code are related though. In short what's causing the kangarooing?

Nobody?

What do you mean by 'kangarooing' and what do you mean by 'coming on and off the throttle'?

[VAG1]

Hard to describe, the revs bounce. So for example if I'm driving the car at 3000 rpm and let go of the accelerator the revs will jump from around by 1-200 rpm. If that makes sense?

Just a thought, there is a switch on the clutch master cylinder that tells the Ecu to let off the power momentarily when the clutch is operated. This allows for smoother gear changes, and removes that jerkyness experienced in some cars.

I see what you mean but the clutch is not being operated, it's whilst it's engaged.
