Hello. Sometimes my speedometer reads above 0 with the engine stopped. It also happened to read bellow the actual speed, after sitting a few days in the cold. The next restart it will be ok. As for reading above 0, usually it needs a battery disconnect, but it also happened to rectify itself.
Lately I've been closing the car without activating the alarm when parking for a few days and this seems to improve battery charge. Yesterday I made a one hour trip, and on my way back the needle was sitting on about 7km/h. I'm pretty sure this is because the battery was allowed to fully charge after a period of shorter journeys.
Now, I know that other brands allow an instrument cluster test (usually by pressing the trip computer button).
Is this possible to to on a 2005 9-3 TiD? The previous time I had to disconnect the battery was about 6 months ago.
Thanks and regards!
Dave
