Sorry for the delayCustomer I'll try to help you. Your radio code is 61422 as long as you still have the original radio installed in the vehicle. Your car also has two open campaigns that will be performed for no charge at the Mercedes dealer. The first is for a new power steering hose and the other is for a new harmonic balancer (crank pulley). You should contact your dealer asap. Let me know if you have any trouble with the radio code.
