Water intrusion is one of the few unnoticed killers of the modern automobile. All modern Porsches are even more sensitive to water damage because of their many delicate electrical control units and computers. I remember this all started years ago when Porsche issued a service bulletin on the 924 to re-route and seal the antenna cable because water could travel along this cable and find its way into the central electrics panel inside the vehicle and create havoc with the electrical system. The main area to watch for water collection in the 986 thru 997’s is the front cowl area. The front cowl area is located just below the base of the windscreen and has water drains on both sides of the battery. There are two front cowl area cavities where debris such as leaves and dirt can collect and in time clog the front cowl drains. When these drains clog water will accumulate in these cavities and at a point migrate into the interior compartment of the vehicle. Water ... read more

We will get back to that, but first some background. Usually a battery will just die from old age. It can ... read more
