I replaced it and it helped consumption is back to normal. The thermostat was stuck open.

I see, thank you.

Hi, sorry for the late reply was busy with other staff rather that repairing the car. I wonder should I replace the thermostat, or thermostat housing? Also an interesting fact, on highway there is no increase in fuel consumption, exactly as it used to be.

I recently had a water leak in my Volvo xc60 2010, through the sunroof. After the leak, the sunroof does not work. I wonder who had a similar problem and what was damaged.
I was told that the sunroof switch is the most likely reason.

I had my car examined by car electrician. He said thermostat is working fine.
What do you mean by the fuel trim?

Had the thermostat tested and it seems to work fine. Do you know what is a normal reading for MAF at idle? My car showed 2.5 grams per second.

Thank you.

Thanks for the reply. Fuel consumption on my car recently increased and I thought replacing filter should have helped (usually this is one of the reasons of fuel consumption increase). When I took the car to the service center they said that US models have no filter and European models do. But it so...

I was told that Volvo xc60, 2010, 3.0. T6 for the US market has no fuel filter. Is it true?
