PSM Failure - 2006 Boxster S - Help Please

[bugley]

Car sat for over 4 months and the battery died.

When I took it out of the car it was found that it could not be save.

Replaced battery with Die Hard. Works great with one exception.

The PSM triangle stays lit and in the information section it say PSM FAILURE.

Tried pushing the PSM buttom while running, holding it down and it still is the same.

Also, car has Sport Chrono package, sport mode will not engage.

Any clues?

Any DIY solutions?

Is ther something that I'm not doing?

Ideas to get this solved short of brining it to the "dealer"?

It is a certifed car for another 2 years.


Thanks,

Bugley
