2006 Mercedes A150 Service Indicator/Light Reset that works.

 I tried all the FSS and Assyst resets to no avail, but this one (ref 2006) worked perfectly and considering the dealer was looking for €350 for a Service C.

The oil and filter to do this cost €50, so a net saving of €300.

- Press the menu systems button;

- The service indicator now displays items;

- Press the menu systems button until the outside temperature display appears.

2006

- Switch ignition on (position one);

- MPH display;

- Press the trip odometer reset knob three times consecutively (Voltage display appears);

- Select the Service menu with the + or – button;

- Service indicator displays items;

- Press the menu systems button until the MPH display appears.

2007

- Switch ignition on (position one);

Navigate the menus and be careful which service you confirm as you can confirm individual actions as well. Have the Service Booklet handy to check the number for the work you've done. It's about all the bloody book is good for! For the 2006 A Class the only way to reset the service data was through the menus, no key sequence worked.
