2004 mercedes e320 maitenave light on

Mercedes -benz E320 w211 Oil level big red light will not go out.changed the sensor still on. Also had low fuel pressure I don't know why but when I Changed the fuel pressure sensor my oil level red light went out.

srs lights are the airbag light most common fault is a wire in the steering which atatches to air bag on steering wheel cannot remember what its called but i have just replaced mine for same problem

MERCEDES BENZ DEALERSHIP HAS TO REPROGRAM THE ANTI LOCK BRAKE SYSTEM AND ELECTRONIC STABILITY CONTROL SYSTEM.IF YOU DISCONNECT BRAKE PAD WEAR SENSORS WHEN REPLACING BRAKE PADS. THE ABS BRAKES AND ESP SYSTEM HAS TO BE RESET TO TURN OFF ESP LIGHT.

Switch on ignition. Cycle left steering wheel buttons till mileage and trip are displayed. Press reset button ( left corner of instrument cluster ) for 3 seconds until reset message appears, release and press again within a few seconds and confirmation will appear on dash. switch off ignition.

Most likely pin switch in the hood area ground has corroded not giving a good signal or switch is bad. Replace as needed and have the area preped on change out.

try disconecting negative battery terminal for a few seconds

is this light on all the time or just when there is something/someone in the seat? usually if there is below a certain weight in the seat the airbag wont deploy, something like 100lbs? although im not sure about this weight in mercedes. if i place something heavy such as a bag on the seat in my bmw the dashboard light comes on. not sure if this helps?

Your Climate control unit may have to be reset. The reset works as follows: With the key in the ignition and in posistion 2 push both the defrost button and the recirc button (at the same time) for five seconds or untill the led lights in those buttons begin to flash. Wait for 30 seconds or untill the led's stop flashing. Switch off the ignition. Check the evaporator temp sensor and pressure sensor for correct functionality.

Hi, Joe here to help,
Without going to a dealer, you need to get a scan tool to reset the srs light. Go to an Autozone store, They will scan it and reset it free of charge.

sorry but your going to have to take it to the dealer to get that light reset.
