Livinia throttle valve issue

I had similar symptoms with my Livinia! Could be a faulty throttle position sensor. Have you tried cleaning the throttle body and checking the control valve?

Thanks for the tip! Where exactly is the control valve located? And is throttle cleaning really that helpful?

The control valve is integrated into the throttle body. Cleaning can help, but with those symptoms and mileage, it's likely a deeper issue. I'd recommend getting it checked at a workshop.

Thanks! Took it to the workshop as you suggested. Turned out to be a defective accelerator pedal module as I suspected. 205€ later and she's running smooth again!
