Subject: Igntion switch has now been replaced - didn't do the job Author: e2djh : member since March, 2008 : 78 posts Posted on: 2009-01-14 16:17:34

I have changed the switch
checked the battery, connectors and earth from battery in the trunk
I have run the car for 30 miles with test 9 running to look at the voltage, with all lihgts on, and it stayed pretty constant...

I will be trying to swap the battery with that from my wife's car (if it is compatible) - what else can there be to check?

1997 750i UK car, Biarritz Blue, my daily driver.
Not the long wheelbase version. Fully loaded, including electric, heated rear seats, now with Mk IV Sat Nav. Bought in Feb 2008 with 74k miles.
