TPMS sensors are not that expensive. I believe they are attached to the tire valves. There is a good chance your car has the system, but the sensors are not installed. I am not sure how you will get rid of the error message though. As far as target tire pressures ,... there is a really good service only dealer in Danbury,CT called Farnbacher Loles. They are really good. They will give you the right answer. 203.798.2929 ask for Robin. She knows everything there is to know about tires and wheels for Porschess. You might as well ask her for a quote to install the TPMS sensors too.

Tire pressure usually depends on the tire manufacture i think. You should have some numbers on your tires. If your wheels are all the same size I don't see why they would have a different pressure on the front.. seems strange.
