Crazy question, my Center Display on my 09 997 TT I set it to Boost PSI last year.

This spring when I bought it out the 997TT the TPMS 4 tires was in Center Display. So I went in to set it back to Boost PSI and when I got to where I need to change it, it was already set to Boost PSI? I just use a Piwis 2 to clear the Service Soon light but I don't think I change anything else.

Check the tires 3 times to make sure they were right at spec.

Anyone run into this before?
