Sean.Smith Cheers, yea figured the fob battery.
Thanks, I have managed to reset it now :-)
It was serviced when the wife bought it earlier this summer. Clearly he never reset it.
Thanks for the help on this.

service/key battery

hello sir. i am in the usa and only worked on one "grey market" vehicle, but i'm sure the standards would hold true. the wrench with the -mileage(1,2,3,...) means you need to have the service light reset. to do this turn the key to position two, press the left button on the instrument cluster twice (within 4 seconds) to bring up the service indicator, switch the ignition off (within 10 seconds) all while holding the left button, switch the ignition back to position 2 still holding the button, wait (aprox. 30 seconds) till the indicator flashes. it will take several tries. please note one wrench means an "a" service is due while two wrenches mean a "b" service is due. now for your nine flashes, this means you need to change the battery in you key fob, instructions should be in your owner's manual. i am a mercedes benz/smart master certified technician so i'm trying to help. feel free to contact me if you need assistance.

Smart passion dash display says -1 yesterday, now -2 today. Ideas?

Yesterday the smart showed -1 on the dashboard display. There was a spanner at one point too, shouldn't be so as was serviced February.
Then the key fob failed, found that to be the battery as flashed 9 times.

However today it displayed -2

It's not temperature display by the way....
I'm sure it means something, but can't find it on the Net or in the book.
