I have just got home after 2 weeks of touring round France in my car, I have only had it for 2 months or so, but the strangest thing happened to me when arriving at the Ferry terminal at Dunkerque. There was a sudden hiss and some steam came from the front passenger side wheel/bonnet. When I pulled over to check it there didnt seem to be a leak but there was a strange noise, type of hissing noise, but it stopped after a while then started again.
After the 90-110 minute journey on the ferry, the engine had time to cool, I drove out of the port and the noise returned for a few seconds then stopped. I have not notice a drop in performance but today when going to get the car washed it seemed that the Air Con was not as cold as it was the day before.
Any advice would be appreciated. I am no master mechanic but I do know a little about cars but this has got me baffled. I have tried to look at the pipes at the side of the engine but I cannot see anything.
Thanks for reading.
