It should be some where on your intake manifold with one or two wires running to it.
have you checked your coolant temparature sensor

The temperature sensor of 206-gti is in the bottom of the right case of mirror.
The coolant used for a 206 GTI is a mixture. This mixture is Glysantin 33 anti-freeze and corrosion inhibitors mixed with an equal amount of water.
Peugeot have two types of IAT sensors. This first sensor for IAT is combined with the MAP sensor. The second IAT sensor for the GTi & GTi 180's are separate entitties and are located at the top of the throttle body.
speed sensor is behind starter motor
Your coolant is low.
on My 2002 gti it is under the intake manifold.
The camshaft sensor is located in the distributor. I believe you have to replace the hole distributor.
I'm sure its in the distributor.
There isnt one.
You must make sure that you have purged all air from the coolant system. An air bubble will not allow proper flow of coolant and could also cause the engine to overheat. Add coolant into resevior and leave top off with engine running. Add more coolant as required. If temp gets too high with cap off and coolant starts to back out of resevior, then replace cap and allow to cool. Remove cap after cool and top up coolant again and repeat procedure.
