Hi all, on Friday night somebody tried to steal my bike, they didn’t succeed but they did in the process of forcing the steering lock off bugger the ignition barrel/switch! my question is can just the ignition switch be changed or is it a case of replacing the ECU aswell as I seem to notice they are often sold as a bundle second hand?

any help appreciated!

Hi Mate, sorry to hear but glad you managed to hold on to your bike. There are others here with more experience than I but I believe the ignition switch itself is not tied to the ECU directly. I think the part tied to the ECU is the security ring antenna that encircles the ignition switch and this is a seperate part. As long as the ring antenna is OK, I think you could just repair or replace the ignition switch, keying it back to your original key and you're back in business.

This is from the Hexacode website: EWS — HEX Code

General description of the EWS system in CAN-bus based motorcycles
The electronic immobilizer consists of 4 parts:

4The Engine Control Unit (BMS-K or BMS-KP)

All sorted at local Bmw dealer! barrel coded to my current key plus housing £129 (steering lock pin was mutilated) not exactly over the moon with having to pay under the circumstances but better than £300 insurance excess! Back on the road - happy days! thanks and regards E

Glad to hear, bike thieves will get their just reward one day. At least you're back on the road with some sunshine to enjoy. Happy trails and safe riding.
