I started getting a " service in 22 days " indication on screen, my car is a 997S built in 10/2005 , the notice keeps counting down , car has 27 k , been serviced many times for DE's , can't find anything in manual about a 5 year date , only see note on drive belt @ 4 year date. anyone else get this

 

It is based on time and milage since the last reset. Talk to your dealer or indi about resetting it.
