After the cold start of Citroen C2, the engine will shake and make a lot of noise before the water temperature is normal. I don't know what's going on.

I have bought my C2 for two years, and it is almost the same in winter. It may be because of the cold weather that the engine needs to maintain a high speed for a certain period of time in order to maintain the working temperature. Just the vibration at this speed and your car vibrate, so the sound is louder and the sense of jitter is stronger. After a period of time, the car becomes hot or disappears naturally after driving for a period of time.

There should be no problem. I really don't trust. I think there may be something wrong with the internal system. You can go to the 4S shop.
