Hi all,
Help pls.
My 2008 xt660z has fault code 55 displayed. I believe the transponder has shorted out causing an ECU issue. I ve been advised to replace the ECU,
I have lost the red key to make matters worse. So its possible i may have to replace the transponder aerial. Is there an immobiliser bypass?
Trying to avoid the �600+ for a new unit..

Any help will be much appreceiated.
