S350L CDI 4matic
Amplifier cooling fan
In my 2010 S with the H/K upgraded hifi, there is an amplifier in the boot which has a cooling fan. I've noticed that the fan is running a long time after the car is shut down (1-2 hours?)
Is there anyone who knows or can check tech data how this fan is supposed to operate? I have had a power drain in the car, so I'm wondering if the fan could be it.
Thanks in advance;

Hello is possible that the one of the audio IC's could be defective. 1 to 2 hours running that's too much. I can check the amp with no problem. I do work with this units, if you what to I can take a look and let you know what I found out.Just let me know.

Regards.
