2009 E320 Bluetec
Someone told me the Auxiliary battery is the problem so I went to the dealer and bought one. The problem is I can't locate it. I've looked in the trunk, the drivers side dashboard and the front passenger side cabin filter area under the hood. The location under the hood has what looks like a computer sitting at an angle.
Does anyone know where I can find it? All the info online shows the battery is under the hood on the passenger side, but for some reason my car is different. The battery size looks different too. Also, is there anything else that I need to look at besides the auxiliary battery? The main battery on the car is new.
Thanks.
