I have been a member for some time, but I have never posted a thread. I had a problem with the brakes on my 2007 cooper s and found the solution on this site. Now I have a new situation. Last week my wife had a message come up on the display saying something about the engine not being at full power. I looked under the bonnet and found the coolant resevoir empty. Could this be the reason the message is on, and how do I reset it? Thanks
