Recently had PCM and ABS lights and faults and asked for ideas on the forum. Got several possibilities, some I will admit I could not see how they could be related, However I checked them anyway. I cleaned the MAF, checked and cleaned the wheel speed sensors and the brake wear sensors and checked and cleaned numerous connections to no avail. Lo and behold when I got to the brake light switch on the brake pedal it was bad. Replaced it and problem solved. Thanks guys for the help. It is amazing how interconnected these Porsche systems are.
