Moin, a “doofy” question: With the SL350 R230 with M 272 KE 35 sports motor I find one magnet switch on the left and one on the right and two camshafts each. Do I see it right that I need two oil stop cables / adapters only for the magnetic switches? Do you also need adapters for the four camshaft sensors? Do you have a purchase recommendation for me?
