E30 OBC Problems. I need help!?!?

[lodgy]

i had a new battery fitted to my e30 e320 and since then my obc has not been able to calculate average speed, range or consumption anyone any ideas how to sort???

Just disconect the battery again, mine used to do this in both my m3 & 325 (e30's)..
Sometimes pressing reset on the function will make it come good

cheers ill try that and let you no how it goes

no luck mate but thanks for the advice

no worries.... I think there is another reset you can do by holding the reset and whatever the button is on the left bottom corner... I could be imagining it as it'd been a while since I've had a car with that OBC, worth a go though...?
