Change millage?
I was looking at the Carfax for my car and I noticed that the car has about 5,000 miles less than reported. Is it possible for some one to change the millage there self or can only the dealer do it. I'm just trying to figure out why there is a difference.
Thanks |

Hello OG Style,
i dont believe the dealer can do it, or just want to but if you google a bit and buy some Equipment its not hard to change the mileage. From china they cheap af and easy to use, so yeah. It's possible to do it. |

Can also be a lazy tech or service advisor. They don't always get it right. 5k less doesn't really increase the value much so I can't see why someone would waste the time

Yeah 5k doesnt seems to be so much. I bought one day a car which had 240k km which are like 150k miles and everything seems to be alright because there was no difference at the control units but when i wanted to register a new battery with inpa i saw that in the history of the IBS there were the last registration from almost 600k km which are like 370k miles. Dont know if the IBS got replaced from another car or this was just the original mileage but whatever the whole interior seems to look like it should be and i dont mind what was written in there. When people change the mileage from the control units they forgot about the one which arent "real" control units like this one and forgot that they have a memory, too. If you want you know you can check it there too.
I calculate (for here in europe where the distances are not as far as in the us) for every year the car was driving aroung like 6-9k miles as reference so when people have much less on their display i dont even have interest in it because it could be A: the car was just standing around and never driven or the mileage isnt original. |

You can't change the mileage to be lower. You can erase the Eeprom in the KOMBI to zero or buy a cluster with less mileage but the car stores the mileage in other modules and that mileage is automatically transferred to the new/erased unit upon installation.

Mileage can be changed to whatever you want, this is true. I have a programmer and the software and have virginized a few M3 clusters but if you don't address the mileage stored in the other modules it doesn't matter what you change it to, it will always default to the higher mileage. And doing that is a whole different level of complexity that 99.9% of individuals don't have the knowledge to accomplish not mention if it's cost effective or worth the possible fraud charges. It's BMW'S built in fraud prevention, yes, anything can be circumvented, but are these cars really worth enough anymore to take the risk?

Is the millage info stored in the instrument cluster? I'm thinking the dealer might have replaced it with a used one and not had the tools to correct the millage. Is there anyway to tell if the cluster has been removed or changed. Thanks

The current millage is lower than what the carfax had on it a year ago. There would have been to be multiple misreads.
06/01/17 - 164,436 (BMW maintenance inspection) 7/30/18 - 169,988 (Last dealer bought it. This is who I bought it from) I bought it with 164,100 miles |

Mileage is stored in the CAS and KOMBI (cluster) along with the VIN. You can change the cluster with a used one but the VIN mismatch will make a tamper dot show on the cluster. To use a used cluster the cluster needs to be disassembled, the eeprom pulled from the board (not in all cases if a test clip works) dump pulled and edited in a hex Editor to erase the short VIN and mileage if it's a higher mileage cluster. Then install and default code to write the new VIN to it.
