Call your dealer and have them check by VIN. I got an ARB7 notice from Porsche and thought all was well. Got to my dealer (not battery related) and was informed that I was actually under ARB6 (no OTA monitoring was done). Apparently you can't rely on what Porsche mails to you.How do you check if your car is ARB6 or ARB7?
