Stepwgn Poor Start and Lagging Acceleration
Summary of the thread
A 2018 gasoline Stepwgn with 190,037 km was experiencing higher fuel consumption, poor starting, and lagging acceleration. The engine light was on, and there was hesitation when accelerating. Initially suspected to be a defective throttle valve, it was later confirmed by a workshop to be a defective accelerator pedal module. After replacing the module, the vehicle's performance improved significantly.

Yes, the engine light is on. When accelerating, there's a noticeable lag, especially from a standstill. The car seems to hesitate before picking up speed. Could this be the accelerator pedal module?

That lag definitely sounds familiar. With the engine light on and the poor start, a defective accelerator pedal module is quite possible. However, I strongly recommend taking it to a workshop for a proper diagnosis. It's difficult to be certain without diagnostic tools.

I took the car to a workshop, and after diagnosis, they confirmed it was indeed a defective accelerator pedal module. The repair cost 205€. The car is now running smoothly again. Your input was most helpful!

I had similar issues with my Stepwgn. Has the engine light come on? What happens when you try to accelerate?
