Is there a way to do this? Yes. Just contact any person in your area that happens to do BMW key programming but aren't a registered locksmith. The procedure to change the mileage in the CAS4 is the same basic procedure to programming a new key to the CAS4 only difference is different things be changed in the EEPROM. Or another way would be to find a cluster used on eBay that has few hundred more miles the your car and then wipe the VIN from that cluster BUT NOT the mileage. Anytime you plug in a higher mileage cluster to a BMW at least on the F10 it will overwrite the lower mileage on the CAS4. Example if your car has 100K miles but you find a 102K mile cluster on eBay once you plug that in and power cycle the car a few times. The CAS4 mileage and other modules will have their mileage overwritten to 102K miles. Now is this illegal or insurance fraud? Most definitely! Its up to you if want to do that or not. Just be aware if you get caught you can get it in trouble but the trouble is very little since you're overclocking the mileage not underclocking (reason being when you lower the mileage the car takes some driving to rewrite the new lower mileage to all the new modules, key and etc., while when you increase the mileage its done within a few power cycles.)
