2003 ML320 122k Issues
Recently purchased a 03 ML320 with 122k miles and here are the issues it has.
-Transmission cooling lines are leaking....Is it usually the entire lines that need to be replaced?
-Hub noise....Sounds like its coming from front left hub
- No sound coming from radio. The car had to be jumped and I entered the radio code and I get no sound from the radio. I checked the fuses by the passenger side and under the hood and nothing. I dont see any fuses near the amp underneath the seat and no fuse near the cd changer.
- When I press the CD button on the radio It says No cd player installed. Even though there is one and its plugged in.
Do you guys think its the amp or radio that went bad? How can I test further?
And lastly. Driver Side Low Beam light clicks on and off. How can I tell if its the ballast or the actual bulb that went bad?
Thanks

ok i resolved the light issue and hub issue... Still tackling the no sound from radio issue. Heres what i did so far.
I checked the fuse behind the radio and underhood. Both are good. I also unplugged the fiber optic cable behind the radio and turned the radio on...The red light blinks once for one second.
I replugged the fiber optic to the radio and unplugged the cable to the cd changer. It did the same. Blinked for a second.
I hear power going to the cd changer because it makes a power noise when i eject or insert the cd magazine.
I did the same to the amp and same result. Red light for one second.
Radio functionality seems to work, except for no sound and when i press cd it says No cd player installed.

Ok i bought the Mercedes Benz Fiber Optic Bypass Coupler
I installed it on the cd changer first. I unplugged the telephone and when I turn the radio on i see one flashing red light.
Still No sound from Radio
I installed the coupler on the telephone. I unplugged the cd changer and when I turn the radio on I hear power going into the cd changer and i see one flashing red light.
Still No sound from Radio.
I installed the coupler on the amp. I unplugged the telephone and when I turn on the radio I see a red light behind the telephone unit and I also see a red light on the fiber optic cable blink once. When I unplug the cd changer I see a red light on the cd changer unit blink once and there is no red light on the fiber optic cable that connects to the cd changer.
Does this shed some light on whats wrong?
