This is driving me crazy with the remote not working on our 2007 C230 Sport. I've checked all of the fuses multiple times and the only one that is always blown is fuse 15 (Fuel Filler Flap Unlocking). Fuse number 8 is fine but I'll be checking the wiring at the siren here soon. Anyone else have an issues like this that they resolved? Going to have to dealer just fix is here soon. Even the IR is spotty as well. Thanks!
