ODO and Clock Reset Only When the Time is set. IBS or Battery?

Vincent_E90 · 11-16-2015, 03:06 PM

Hey guys! I've had this problem where the clock and ODO reset every time I shut the car off and left it for more than a few hours. After doing it multiple times a day I said screw it and stopped setting the clock, and it was good for the whole weekend (I ran the trip meter up to like 50 miles). Today before I went in to work I decided to set the clock again and when I left to lunch it had reset again. I checked the battery charge against my Dad's 07 E92 335i (mine being an 08 e90 335i) and it had a better charge than his. Anyone else have this problem as well? I was thinking it's the IBS sensor but have no way of telling to be honest, no codes or anything.

Thanks!

Edit: It always starts up no problem, but when the ODO trip and clock reset, I cant use comfort access/

Sounds like you need to get your IBS checked out.

What was the actual voltage number?
and how much does it sag when you start the car?
How old is the battery ?

It's the OEM battery, so I'm afraid of buying 200 for the new IBS cable when it was just a battery. I'm going to swap the IBS cable with my dads e92 and see how that works for me.

I cant remember off the top of my head I'll have to check when I get home from work, I'm not sure what sag means in the terms of starting the car, could you clarify? And its the OEM battery from 08 so 7-8 years old. I haven't checked the date on it yet.

change the battery first

Hey, just a follow up on this. I didn't get around to changing the battery, but I did find a cheap IBS sensor off e-bay for like 70 dollars and been driving it around for the past few days and no clock or ODO reset so hopefully it resolves this problem.

your battery is 7+ years old and you are wondering if you need a new battery?
