How do I disconnect the immobiliser on my RT1100 Bmw

no voltage

could be battery flat or loose terminals
alternator
start motor
engine bay fuses or relays

next to check os immobiliser

if you cant sort it .. may need a tow to the bmw service center

try using a scanner to reset the immobiliser. It may work

How do you know it's the immobiliser, what tests have you done?
I suggest you try a BMW forum, but you'll have to be bothered to give a lot more info than you gave here. There are lots of things that it could be, the battery in the fob, the sensor ring, your car battery, the ignition switch, try another key etc etc BMW Forum BMWLand or http://www.bmwforums.info/

Removing the negative batt won't help,go and run a scan on the body system(bcm) and see if there is any related fault code.pls do

change them but check them they may just need a little spray of wd40 not grease as grit will get in some how and start grinding them away

Hi

There is one method you ca try, first ensure the car is unlocked but with the keys out of the car. then disconnect the battery for about 2hrs, overnight if possible. this should reset the car immobiliser and ECU. When putting the battery back on connect the red first then the black i that order.

If no joy get back to me I have a few oher solutions.

Regards and happy new year

i think it the electronic ignition immob....which has about 2 million permutations, only accessable with the proper BMW coded key

flashing means its not working

check wheels sensors are working with meter

the 2 wire connection or sensor is too far away from pulse ring

take to dealer to get this sorted ,sounds like an immobiliser problem with the classic faults
