Mokka Fuel Consumption Starting Issue

I had similar symptoms on my old Peugeot 308. Turned out to be a defective accelerator pedal module. The car was overfuelling and struggling to start.

Thanks for the info! Was it difficult to diagnose? Did you notice any other symptoms besides the fuel consumption and starting issues?

The diagnosis wasn't straightforward. Besides the consumption and starting, the engine idle was rough sometimes. I would recommend having the throttle position and accelerator pedal module checked by a workshop.

Took your advice and brought it to a workshop. Turns out the accelerator pedal module was indeed faulty, just like you said. Repair cost me 205€. Thanks for the help!
