Valmet is the name of the company in Finland that assembles some of the Boxsters.
You have an arena red 2.7 or base Boxster.
224 bothers me.  I am going to show it to the guy I know at my dealer.  In the past he spoke to a German guy to figure out some of the codes that are not listed.  Our cars never had limited slip.
