Title: Unintentional acceleration
Post by: Trumpetier on November 17, 2022, 14:30:41
I tried to comment on a thread that was written about this subject a few years ago, but was unable to. My 65 plate i30 diesel yesterday started to speed up when my foot was off the throttle in 3rd gear. I've heard it could be something called "anti stall" but I could of been doing approx 25 mph. I've had the car since January, and have noticed the anti stall feature from stand still , but never like it was yesterday actually driving and in 3rd gear.

My previous i20 diesel never did any of this and this was also a 65 plate.

Is this normal ?

I wonder if it is a side effect of a DPF burn off. I don't have a diesel but there has been plenty of chat on here about them.

Both my i30 diesels behaved this way. As you say people call it anti-stall and I believe that's exactly right. Extra fuel is added to a loaded engine to keep it spinning, and with the torque generated by the long piston travel you get the feeling of acceleration - the higher the gear the faster you will go.
