Odometer Mileage Decreasing - yes really!!
Have to admit I have no idea what's going on here:
Purchased my daughters BMW 1 series last year and a week later it went in for warranty work (dual mass flywheel). Not trusting the garage with the car for a week I took a photo of the mileage before and after and it dropped by 200 miles. Took it up with the dealer and they denied any knowledge and in fact got upset I was in effect accusing them of clocking it.
Fast forward to Wednesday this week and the car died and was jump started. This time the mileage dropped for 72,000 to 67,522 and remained at that.
Last night I came home fitted a new battery and it dropped by another few hundred miles when connected up.
The car now has less miles on it that the Last MOT and before we purchased it 10 months ago.
I know how mileage is stored on the Zed in the LCM, odometer and I think ECU, but WTF is going on with the 1 series??

Sounds like a case for "Honest John" at the daily telegraph, he would probably know of any strange goings on with the 1 series.

Re: Odometer Mileage Decreasing - yes really!!
What does the service interval say - does it go up by thousands of miles as well?

Christine- certainly seems like it
Good point re Honest John
PVR - not checked that out. Did the battery late yesterday when I got back from Ireland and car is out for the day. Will look later.

Re: Odometer Mileage Decreasing - yes really!!
I'd take it up with BMW and tell them that if they don't fix it for free, you'll be talking to the local paper and Watchdog giving them a story about people not being able to trust the odometer readings on BMWs

Re: Odometer Mileage Decreasing - yes really!!
The other thing is, how true was the mileage when you bought it if this issue existed before, i.e. was the true mileage higher but had been dropping before or do the MOT certificates indicate it is a recent problem?

Re: Odometer Mileage Decreasing - yes really!!
Everything looked good from services to MOT's checked out online. Look of the car frankly is of <50k so no issues there. seems to be related to taking the battery out/disconnecting the power.pvr wrote:The other thing is, how true was the mileage when you bought it if this issue existed before, i.e. was the true mileage higher but had been dropping before or do the MOT certificates indicate it is a recent problem?
I'll speak to BMW, but somehow doubt they will either believe me nor fix it.
My preference is to understand how this can happen. When you stop and think, it's beyond bizarre and while it sounds good the car could become unsaleable...

Re: Odometer Mileage Decreasing - yes really!!
That is very strange indeed.. This hasnt tripped the tamper switch?
Can you replicate it by unplugging the battery? Atleast you could show the engineer it!

If by tamper switch you mean the dot that appears on the mileage reading, then no.
In a way it was replicated by changing the battery as that dropped the mileage some more last night. Don't want to just keep doing it as who knows what it goes to next time...

If you can replicate it by disconnecting the battery and then reconnecting, maybe an idea to video the process and post it online. Am sure someone would be interested in this issue, even if it's not your local BMW dealership.

Re: Odometer Mileage Decreasing - yes really!!
Did at any point you hit 88mph?
This is absolutely baffling! I would love to know what is causing it but cannot begin to think what. Perhaps send BMW a video when you remove the battery terminals? To prove it?

Re: Odometer Mileage Decreasing - yes really!!
Cars back and done a 40 mile trip and has correctly started to increase mileage as driven, but still around 5k shy of actual
Next service is now showing as due, so that's got zeroed out during the error, but easy enough to reset.
