V70 fuel consumption hard start
Summary of the thread
A 2012 Volvo V70 is experiencing increased fuel consumption and difficulty starting, particularly in cold weather. The issue might be related to a defective throttle valve, but another possibility is a faulty accelerator pedal module, as suggested by someone who had similar symptoms with a different car. It is recommended to have a professional diagnostic check to identify the exact cause and potentially save on repair costs.

Thank you for your input! That's interesting. I was leaning towards cleaning the throttle body first, but the accelerator pedal module is a good point. Could you elaborate on how you diagnosed the accelerator pedal module as the issue? Did you experience any other symptoms?

Well, besides the fuel efficiency dropping and the rough starts, the car would sometimes hesitate when accelerating. A mechanic ran a diagnostic and it pointed directly to a faulty accelerator pedal module. I'd advise getting it checked out professionally. It might save you time and money. The repair was around 205€.

Hey! Those symptoms sound familiar. I had a similar issue with my old 2008 Opel Insignia. Higher fuel consumption and hard starts? Have you checked the accelerator pedal module? That was the culprit in my case.
