READ ANSWERWhat is causing what appears to be an intermittent control board failure?
Friday 12/12/2025 | 2014 | Cayman S | Electronics
At seeming random times, a control board (I think) has a failure that disables PASM and adaptive cruise control (and one other selectable feature I do not remember). The problem has existed for some years. The problem can be cleared by stopping, turning off the car and engine by removing the key and restarting. My guess is that this "reboots" the faulty board.Typically, the car then operates fine for some time, but the fault always recurs given enough time. It sometimes occu ...
READ ANSWERI'm considering buying a 1998 Boxster that seller says needs a new clutch "right away." How much should I expect to pay for a new clutch? Is a Kevlar clutch recommended? Should other parts, such as the flywheel and pressure plate, be replaced at the same time as a reasonable precaution? Thx.

Monday 12/08/2025 | 1988 | 944 Turbo S | Body

READ ANSWERI bought a 2024 Cayman base last year with the usual summer tires on it. It's winter now in upstate NY, and I'd still like to drive the car around as a daily driver; however, the local dealer says that it isn't possible to put either all season or M & S tires on this model. 1) Is this true? and 2) if it isn't, what is my best option--assuming there is one. Thanks in advance.
