Mercedes Classe E - Video tutorial

Model: Mercedes Classe E W211 - Years 2002-2009
Part: Engine
Operation: Check battery efficiency status

If the battery symbol appears on the instrument panel display when the ignition is switched on, it is likely that there may be a problem with the efficiency of the battery or the recharging system, or the alternator. It is therefore necessary to measure the voltage at the battery poles both with the engine off (a value of just over 12 V is expected) and with the engine running (expected value 13, 8-14, 2 V). Also, if you have the Battery Test Tool, you may want to run a test to more accurately assess its efficiency. The same operation must be carried out on the buffer battery located in the engine compartment, on the passenger side, immediately under the windscreen.

How do you open the fuel flap of the Volkswagen Golf 5?

In order to open the fuel flap of the Volkswagen Golf 5, you need to press the appropriate button inside the passenger compartment, which is located in the rear part of the glove box on the driver's door.
