Reset a service light 2003 ml350

you need to use the diagnostic program too do this step after a full service
ie check and replace brake pads and fuel filters paper filter oil and fluids and filters then reset its ecu

try to ask the local garages who has the right cable and tools and ask them to either do the full service and reset it
or reset it if youve done a service
this only comes on at a major service point or if the ecu detects an issue so is not just a short service
anything from worn pads to bad oil presure can cause this too trigger as well as miles count

you cannot its a dealer only thing I have the same issue it costs around 30 pound for them to reset it some times you can buy reset tools from ebay cheap but don't always work

according to my alldata book a 2007 model can only be reset by the dealer ,but look on some of the chinese automotive software sites on the web as no doubt they may have cracked it and produced a small unit to clear the service inspection light by now

In the owners manual should be a self reset procedure. If you cant find it hop on over to benzworld.org and look around.

A common problem with this is a dead battery this will put it in lockdown-dealer area.

one of the engine sensors must be having a problem! have the vehicle diagonised! use a scan tool please

Turn key to position 2. press the button to show the service due light. release button. turn key off. press and hold the same button to view the service light, within 2 second turn key to position 2. wait up to 10 second and the light will reset to show new service. This may take a couple of trys (make sure the doors are shut).

this needs to be done by a mercedes dealership/garage
