I recognized I have this on my 85.5 N/A today as well and cannot find anything online about this code and V61.
While C88 has been mentioned several times as far back as 2001, nothing has been said on V61 (according to the search):
What is 944 option code C88?
Option Codes
What is C88 in my option code
WHAT the HELL is c88!!!!!!
In all these posts including this one, all we have is a lot of speculation and nothing concrete. I wonder why this is.
Can anyone answer this once and for all what the C88 option code is (and hopefully the V61 option code as well?)
Many thanks!
