So let me get this right. The tech placed your E46 key into the slot and the current mileage and VIN are known?
What about other info?
KP said:Perhaps the key encoded protection system chip keeps record of these things?
Each key is coded for a specific car so it would make sense to use the VIN as no two vechicles have the same one. The VIN stored on the key needs to match the VIN stored on a chip on the car or no start.
Kaz said:I read somewhere in some E65 tech info that the self-charging style key on other current models store the VIN and mileage at the least. WIth that, and the fact that the odometer reading is stored in the cluster and the light switch, rolling back the odometer would be pretty tough...

But my key is not self-charge
The two "main" keys both have batteries in them, to power the remote funtions and keep the chip memory intact. The batteries recharge when you drive with them in the ignition. The manual says you should use each key at least once a year to keep the battery alive.

Do I smell another project for Vince:dunno: :yikes:
Ya, I would buy that key-reader thingy, walk around town and ask Bimmer owners to insert their keys. And say "Ah-ha! Your mileage is XXXX! Congrats!" :lmao:
I am just a bit paranoid, y'know. Perhaps there is a nano-GPS chip in the key. And a centralised tracking system somewhere at BMWNA. Ok, time to stop visiting those adult bookstores already...j/k!
