Hi everyone, new here, have an S63 AMG coupe with approx. 12,000 miles. The function buttons on my steering wheel are not lighting up at night (all are out), is there a switch/setting/fuse for this? Or is this something I should ask the dealer about since car is under warranty, I thank you in advance for answering.

Hi there ;-), Just saw this post and I have the same issue. Multi function steering wheels illumination not lighting up. Sometimes they flash. When I attempted to turn up the dash board illumination they started flashing and then went off again. MB dealer has not been able to work it out and suggested replacing the steering wheel.

Seems like there is an issue and they rather replace a part than investigate. They are not even sure if it is the steering wheel.

Anyone help will be highly appreciated.

Thank you.

its your control module in the steering wheel thats malfunctioning. no need to replace the whole wheel.
new control module is like $150 on ebay

Thank you for letting me know. It was with the Mercedes dealer for 3 weeks and the car had many errors registered. It is amazing that they could not tell me it is the control module. They even changed the two blocks of switches on the steering wheel!

dealerships are filled with clowns who just do what the repair manual says. they dont know sh** about f*** when it comes to the actual internals of components.

The control module tells the buttons when they need to perform a certain function. when the control module is faulty itll either complely not work or some features will be malfunctioning. replace the module
