2004 MERCEDES E320 READS MALFUNCTION BATTTERY ICON WITH MESSAGE VISIT WORKSHOP, for weeks while car functions flawlessly.

Hi there

BAS is the Brake Assist System and if there is a malfunction it would only come into play in an Emergency stop while applying full pressure. BAS applies full braking force because people tend to lighten up their pressure on the pedal in these situations. I would suggest that the best thing to do is go to a Workshop or Service Center and have it checked out. Please remember to put a good rating on my profile.

Kind regards

SOURCE: method of charging a 2004 Mercedes E320 battery

It is always safer to charge the battery out of circuit, Removal of one cable will insure you can safely charge without hurting electronics on board. Generally if your battery is already sufficiently charged it acts like a capacitor in the circuit and will prevent damage, but many battery chargers do not always put out a pure dc voltage and this can damage electonics.

Hello, You probably have brake pads that are worn down to the sensors. You will need to take it to whomever does your repairs. It could be either the front or rear pads or both.

If you find this info to be correct, please enter a (fixya) rating
