I was wondering if anyone know of what computer controls the Heated Seats, Keyless Go, and brakes? My instrument cluster is constantly red and says Brake visit workshop. I have already replaced both batteries with brand new ones. I had a leak in my car so I believe the computers got shorted out and need replacing. My heated seats and keyless go do not work. Any ideas and help would be greatly appreciated.

Thank You,

Ty

There is a whole stash of electronics under the carpet on the passenger side floorboard, you might try drying that out and cleaning things up first.

They are all different control units. I would find someone with a dealer level scan tool to check the codes before you start replacing control units. Brake warning could be as easy as a brake switch or you might need a pressure accumulator or SBC unit. Luckily, that would be covered by the extended warranty.

Actually the SBC on E55 has been extended to 25 years according to Mercedes Benz.
Call your local dealership for more details.
