i had this on my old car, it was the multi plug behind the speedo that needs replacing, you can be sure to tell, when it does it again, just hit the underside of the steering columb and it will all work again, speak to vauxhall, common problem with them, but as for the speaker not working i dont have a clue

Doesn't a spanner mean it's due for a service?

thats not the engine management light the one below it is. i have had the light you are on about come on a few times but then i restart the engine and its ok again no problems

gettin a pic of a car and a spanner on my mates corsa c, i think its the cars version on the eningine mangement light for none engine things.

anyway the speedos not working and the front left seakers also stopped!

any suggestions?
