Trafic loss of power

I had a similar issue with my 2018 Opel Insignia: reduced engine power and the check engine light. Your throttle valve may be defective.

A defective throttle valve? That sounds expensive! What exactly went wrong with your Opel? Was it just a straightforward replacement, or did they have to fiddle with the electronics too?

In my case, the accelerator pedal module was faulty. The electronics inside were defective, causing the throttle valve to misbehave. I suggest taking your Trafic to a workshop for a diagnosis.

Thanks for the heads-up! I took it to the shop, and you were spot on. The throttle valve was indeed defective; they said it's a common problem. New throttle valve plus labor came to 265€. Runs like new now!
