Figo charge air temperature sensor error

Sounds familiar! I had similar issues with my Figo. Reduced power and that awful hissing noise. Have you checked for temperature fluctuation in the air intake? It's like trying to run a marathon with a clogged nose.

Could you clarify what you mean by temperature fluctuation in the air intake and how it relates to the charge air temperature sensor?

If the temperature readings from the sensor are erratic, it could indicate a faulty connection or sensor. It's like the engine getting conflicting messages, so it reduces power as a precaution. Given your symptoms and the potential cause, I'd advise getting it checked by a workshop. It may be a simple fix, like mine was, but best not to risk further damage.

I appreciate the advice. I visited a workshop and it was the cable connection of the charge air temperature sensor. Repair cost: 95€. Problem solved.
