how to get a service indicator light off a Peugeot 307 55 plate

The light will only go off when it has been reset by the garage using a hand held diagnostic tester as part of the service.

Switch ignition OFF.
Press and hold button on dash display
Switch ignition ON.
Keep button depressed for 10 seconds.
Display will now read 0 and 'spanner' symbol will go out.

Hi
only data l have covers up to 2004
but this might work

Press and hold the button between the instrument panel warning lights & the speedo

switch Ign on

keep button depressed for 10 seconds

display will read 0 & spanner symbol will go out

hope this helps

Once the car has been serviced and the oil has been chaged the light should go off itself - l work in a garage!

Take a fuse out!

If none of what the other people have said works it definitely tells you how to switch it off in your handbook. l own a Peugeot and I've seen it. good look!
