Mercedes-Benz S550 ProblemsHVAC Blower Motor May Fail
The HVAC blower motor may fail. This is commonly caused by water entry through the cabin air filter areas during heavy rain or snow. Failed blower motors should be replaced. Our technicians tell us there is no special fix for this issue at this time.
The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

I noticed today by left rear wheel undercarriage soaked in fuel.
I went to the shop and they said the diagnosis machine said my amp is bad? Could it be the wires connected to it? Before I spend a lot of money buying a new one is there a cheaper option?
