I have noticed a leak coming from under the engine on the above car which I bought 2nd hand a month or so ago. It only happens when the car is parked after use. Any ideas on what this might be? Should I request the dealer that sold it repair it as I paid for an MOT under the previso that if anything is wrong with it they would fix it.

I am wandering what happened with the MOT though as I have already had a brake looked at by the dealer that was squealing and also there was a rear brake light out so it sounds to me as thought the MOT was done without any testing...

Any help would be greatly appreciated!
