HDi throttle damping

Post by bernie »

My Xantia 110 hdi has a damping effect on the throttle. ie. the revs die down after the pedal returns.
I know the 1.9td had a physical sprung damper but there is not one on the HDi.
It is not the cable sticking.
So does the accelerator pedal position sensor have a slight delay?

It is most likely to be an ECU function, most modern car do it nowdays

My 1994 Xantia 2.0i does the same dumb thing.
I don't like it, because it slows gearchanges for rev-matched clutch engagement, but modifying it is too hard for the resultant benefit.
Sometimes the engine goes unstable and surges repetitively if I come off throttle , which is horribly inelegant.
Never happened in my Carby Cits.
My right foot should be the only control above idle revs.

The HDI has a fly by wire throttle...
You could check whether the cable is free, oil it and work the oil into the cable and see whether that improves it or not.

Hi Kowalski,
I've disconnected the cable, it's the fly by wire bit that's got a lag.
Just want to know if their all like that. Ta
