my dad has an 05 sl 500
problem one: no matter the tire pressure, the TPMS warning goes off.
problem two: no matter the oil level, the "engine oil level tool high" warning goes off.
i have notes from the mechanics at mercedes for review, but the after market warranty doesn't cover either problem. if anyone would like to make some money on the side an knows how to work on said car, send me a pm or text me at 480-495-9137.
