MODS -Sorry if this is repeated from the E31 8 Series Forum but no one seems to be replying with any more ideas, so I hope that it is okay to post here.
Since I got my 8 Series the alarm flasher -known as the Tell-Tale light from the interior of the car has not been flashing when I lock the car. So I checked all the fuses and all is well. I then checked the voltage across the LED Tell-Tale flasher from inside the car using a multimeter, while I'm locked in the car (so that the alarm becomes active), and there simply isn't any voltage or anything showing on the multimeter. So, I decided this time I should see if the alarm is working so there I was inside the car jumping up and down and nothing was going off!!! I could turn on the exterior lights, move the gearstick from P to any other gear!!
So that is why I've came to this Forum section, as I think it is more appropriate and also becuase I really am not sure what to do next or where to go to.
Many thanks in advance,
