You need to have a OBD2 fault code test performed to determine what codes are present in memory, based on that test you do the prescribed diagnostics testing.

Thermostat is not working properly means water is circulating through radiator without even reaching engine's operating temperature.

Sadly a common fault with 207s is random fault warnings coming up on the display.

If it's a real fault, then you should notice a fall off of performance and this indicates a trip to your garage to get it fixed.

If the fault comes and goes, or there is no loss of performance, do what most 207 drivers do and ignore it !

A dirty fuel filter could prevent sufficient fuel for higher RPM performance. murf427

There is no such thing.

If youre refering to Antipolution warning coming up on display:

i think you might have to much oil in your vehicle. i would say change your oil and if it still does it i would take it to the nearest shop and talk to them about it.

depends on your model and engine. mine does on empty motorway max. 150 km/h and on hill/slop upwards 120km/h. If you let reprogram your ecu for performance may be you'll gain more speed (google it for ecu reprogramming and you'll find more infos).
