206 gti ecu

hello friends peugeot 206 gti my engine's brain (ecu) 2 times a little click sound comes in 10 minutes what is the reason? There is no malfunction, the vehicle is normal. Also, is it normal to warm the medicine when I start the vehicle?

the subject is up to date.

I don't think so but do you use air conditioning at that time. I have a digital air conditioner. When the air conditioner starts to work, there is a clicking sound when it is turned off from the front & nbsp;
