So it has been a busy month for my TT. Earlier this month I corded a tire. Not a huge deal because I have been meaning to correct my rear tire size - I'm running 997 rims with 235-35-19 front tires, so I really wanted to get into a 315-25-19 instead of the 305-30-19 I was running to match the front to rear diameters.

Within a day of driving I blow the regulator in the alternator and drive my car on battery until it quits. Get alternator fixed.

Today I went for an alignment because the previous rear tires had severe outer edge wear. Sure enough, camber on one side and toe (front and rear) is off.

During the drive home PSM engages during very modest steering input with very modest speed on a freeway ramp. This has repeated itself several times today.

I read someone mention something about resetting the steering angle sensor (oh, I just remembered, my mechanic said that he had to center the steering). I'm sure the steering angle sensor was not reset.

Could this be the problem? Might the severe power brownout have damaged the PSM system? Other?

Thanks,
Trevor
