I dont see any faults on the iDrive screen.
Yeah I'm thinking I need new spark plugs. It's an '08 535i and it runs like a dream but I did not get any info from the previous owner stating he changed the spark plugs. You think I'm better off ordering the parts from Bosch or BMW. I can get any part from them wholesale because I work at a dealership and we have plenty of Bimmers on our lot.
