My dealer told me my 2014 Boxster S is due for these updates:
WF27: Perform PCM (with XM radio) update
- WF86: Re-program DME
- WKJ3: Replacing tank leakage diagnostic module.
I am not having any issues with car and subscribe to the if not broken philosophy. Has anyone had these done and if so experiences. Where is the tank leakage diagnostic module located? that one
gives me pause.

I just had a conversation with our dealer on 40K servicing and the tank module came up.
Warranty will cover it supposedly. No details on what was going on to prompt the repair were given.
