I haven't driven the beast for about 2 months, but about a week ago i noticed a puddle of fluid growing under the car. It was the reservoir for the SLS and power steering overflowing - I've started the engine and the level went back down to normal. There's been some hot days, could it just have been some trapped air in the pipes expanding in the heat (we've had a few days of nearly 30 deg c - v. hot for uk) or something? Or some sort of expansion vessel to regulate the pressure? Or something more serious? Anything I should do other than just top up the reservoir to the normal level again?

Any ideas much appreciated!
