That "18" on the display is number of days before service is due. When the wrench and the clock appear it is to indicate "days left" and the wrench by itself indicates "miles left".
This may be a rhetorical question but I just had my oil change 1 month ago at auto repair shop and the light just came on right now and says it’s due in a few hundred miles. Could it be that they didn’t reset it?
I have c230 2000 and ac is not working.Had it to mechanic they test the compressor they said its not leaking, it could be electrical problem, i replaced myself evaporator sensor still nothing, any suggestion much appreciate it.
At 0:44 there is a light on your dash which appears on the bottom right side (next to the brake light). What does it do? Mine has been coming on and off. It looks to be external lights or something 🤷♂️
