I installed a new battery in my 2004 325xi and everything works Ok but the odometer changed from 83,000 to 49750!
Has anyone ever seen this problem? Is this normal or is this some kind of freak thing? Is this a dealer only fix? Any help is appreciated!
and....this is a problem? LOL. (freak thing, I would think,...in fact I would go further and consider it a gift from the car angels above)
It is a problem since the state dmv keeps mileage records and future inspections or a sale will reveal the lower(wrong) mileage!
Odo glitches have happened before. Try taking the battery loose before bed and reconnecting it in the morning. It might not read correct immediately, but could correct itself within a day.
Smell that? ......German leather and palm sweat.
are you sure it's displaying miles?
IF MY CAPS OFFEND YOU, BLOCK ME.
AND IF YOU NOTICE THE FIRST LETTER OF EACH WORD CAP'ED...... IT'S DONE AUTOMATICALLY BY THE FORUM BECAUSE I TYPE IN ALL CAPS.BUT IT DOESN'T ALWAYS DO THIS, LIKE WHEN I QUOTE OTHER POSTS.AND IF YOU DON'T LIKE THAT, REFER TO FIRST SENTENCE IN MY SIG.
Resale value just went up. $$$
immediately take it to another state & sell?.... ...or doesn't it work that way in the USA?
Does the car have (or did it ever have) the mileage/tamper dot as seen see here?

I bought an E36 once with the "tamper" dot. For the E36 at least, there's a way to reset the system so it displays the true mileage. I did that and the mileage reset to a different value and the dot went away.
I'm trying to remember.... I'm thinking it was about about 151,000 miles and after the reset it went up to roughly 154,000. Not a big change, but it was nice to resolve that dot.
I bought the car with a bad head gasket but a nice body and interior for $1,400, so I wasn't too concerned about the dot. I ended-up with a really nice 97 318ti for under $2,000.

I took my 325xi back to the dealer. They ran diagnostics on the car and the cluster failed the test. They don't know where the 49751 figure comes from when you disconnect the battery (it does it every time).
Bottom line: Car is out of warrenty. Dealer says this is not covered by any known defects. Fix is to replace the cluster to the tune of $1016.00. So I paid my $115.50 diag. charge and left.
Delaware DMV says : no big deal! Just keep track of approximite mileage and report same on sellers sheet at sale time.
Odometer reads 49850 and counting! By the way, my key has the correct 83311 mileage stored in it, according to the dealer!
Learned s-thing. Didn't know a keyfob stores odometer reading. (I suppose if one got a new, replacement key, it would have to be keyed to correct current odometer reading vs starting @ zero.)
The diamond shape keys pick up mileage after being in the ignition in about 10mins or 10 miles of driving. I would also be careful about cheap obd2 scanners as we're starting to see cluster failures after attempts to scan the vehicles. The mileage is store in two places depending on the age and version of ews: the cluster and the light control module, any chance the light control module was replaced, or did you have an after market scan tool used?
Consider it a gift.. I'm going to go swap batteries on my bmw this evening and see if I get such luck, lol..
Go trade it in..
Most states' DMV require the last known mileage and date be engraved next to the VIN tag. Could even be a Federal mandate.
Before changing battery, the installer should jumper another battery at the remote terminals in the engine compartment to prevent erasing of the memory of all items in the car.
That's illegal in NJ to tamper with the milage, If you didn't do it don't worry lol. OH well, it is not a bad thing it happened right? ;o
Intentionally tampering with the mileage is against the law, having the odometer break isn't. In Georgia, it would simply be titled with an "Odometer Discrepancy" note.
2004 bmw 525i battery died and jumped it and now odometer reads 30,000 miles more? How the heck did this happen?
