    Default Thats 2.0 bar of pressure or 29 psi. Your car is only

    supposed to have the 1.4 bar or 20 psi cap. Buy the 140 for it before you blow the heater core seals.

    Default There was a cap recall in 1999 or therebouts , Phil

    will be familiar with it and should know the details, the early 525 used the 1.4 bar cap and most of the other 5 series used the 2.0 bar cap. The recall replacement caps were designed to vent coolant more rapidly if excess pressure built up in the cooling system. The fear was that excess pressure would occure in an overheating car and the heater core or heater core seals would blow and scalding coolant would hit the driver or passengers feet. The recall replaced all these caps with the new design. If your cap has never been replaced i think the dealer will still give you the new design cap for your car.
