I agree, I don't think during a routine maintence they would check for that. Unless it was a warranty call for a blow engine or computer.
I don't think its a matter of BMW's means to do it but more why would they bother.
Performance upgrades are profit to them, fast and harder your car runs the quicker the parts burn out. I believe that those effects do not appear in a small enough time frame to effect their warranty dollars. This is only based on my speculation not factual though.
: Do you have proof (i.e. a tech printout or such) that the dealer can detect the Jim C. chip?
: I realise that the EPROM is going to have a different checksum, etc but does the dealer have access to this information from his diagnostics equipment? Also does the dealer record the checksum in the BMW NA computer? If he is not doing this then the current checksum could change by upgrades (DINAN, Emissions, etc) from a different dealer etc.
: The dealer's diagnostics equipment is limited in its function and I am wondering how much you are speculating and how much you know as fact.
