850 MJ 97 B5252 144 PS Servus together, as already written above the moose jumps normal again after 2-3 seconds, when it is on it runs without problems I noticed only in the cold condition or only now at these temperatures, after I have read some it will probably be the immobilizer. Where is the usually the fault, at the key or antenna ring ? If antenna ring, this is no longer available how to proceed ….can one be the existing one repair ? A new used will probably bring little since these are already as old as mine especially as they also have to be learned. Thanks and greetings Stefan
