Yes, thats right.
Replace the Thermostate. It is in Front of your Motor, behind the Cooling Propeller. You do not need to dismount ther Propeller. The Part cost about 55 EURO and after replace your Engine will be happy and your feet will be warm ....

Hello ,

I need a technical advice.

It seems to me that this subject is evoked on the main german forum by clube31 but i does not unterstand. : : :

I drive yesterday my 8 with very cold temperature (0°C) and i realized that the temperature indicator stayed towards the cold.

I wonder if it comes not because i modified last summer the front spoiler to install a CSI' spoiler. which seems to set of more air in the engine.

For this CSI'configuration maybe there is a modification on the temperature probe(position or setting)?

Thanks for your help

PHILIPPE
