Hi! I'm new to Boards so hope I'm posting this in the right section.
I was driving my BMW 318ci today when the warning light came on indicating that the coolant level was low. I pulled into a roadside garage to get coolant. The engine had steam coming off it and when I examined it there was water lying under the engine, not very much but the area was damp. I drove the final 15 miles home and when I parked up there was a lot of steam coming from under the bonnet. I checked on the car 20mins later and the engine was still steaming, although not as much. What could be causing this? The engine temperature display is normal. It doesn't seem to have effected the car's performance which been perfect since I got it fully serviced in March. I'm really hoping it's something minor that wont cost a fortune to fix. Any help would really be appreciated, thanks!
