Mixture too lean F10 M5 linked to poor battery?

Hi people,

My car is triggering eml with the code read out with the following with my Carly:

Fault Code: 118010
Fault Explanation: Mixture control, across the databases: mixture too lean

Immobilizer System
CAS
Fault Code: 930769
Fault Explanation: eactivation Terminal 15: reached OSFG
Fault Code: 93076A
Fault Explanation: eactivation Terminal 15: OSFG achieved, but Abschaltverhinderer active
Fault Code: 93076B
Fault Explanation: eactivation terminal 30B: achieved OSFG Fault Code: 93076C
Fault Explanation: eactivation terminal 30B: OSFG achieved, but Abschaltverhinderer or legal consumers are actively

Sunroof / Roof
Roof / Dach Funktionen
Fault Code: 801A4A
Fault Explanation: :Car alarm: deactivated inclination sensor and interior protection / Deactivation IRS and tilt sensor per customer function


Junction Box
Fault Code: 8020E6
Fault Explanation: :Ignition model: Startfaehigkeit endangered Fault Code: 8020E7
Fault Explanation: :Terminal 30B Active achieved Startfaehigkeitsgrenze or Kl 30B long time actively.

Body
Fussraummodul /FRM
Fault Code: 800E96
Fault Explanation: :Rear right turn signal circuit or short circuit to Ubat / Power Management: Consumer shutdown exterior mirror heating / Rear right turn signal line interruption
Fault Code: 800F92
Fault Explanation: :Welcome light-repeat active

Integrated Chassis Module / Längs+Querdynamik
Fault Code: 482791
Fault Explanation: :LDM feature high-level navigation data flawed

My question is, could this be linked to a poor battery?

Dealer mentioned my battery’s a problem and the battery died a couple of times.

Or is this something else altogether?

Dealership did an inspection check last time and found no leaks or issues with engine, but mentioned oil cap was a bit loose so could’ve triggered an issue by building pressure or letting air in (there was a misfire in code read out the first time the eml came on)

Or is this more like spark plug and/coil packs?

Thanks in advance people!

My 17 Range Rover Autobiography threw suspension fault error because battery was faulty. Just saying it may be the battery in your case too. I was told that low battery voltage made sensor throw wrong signals back to ECU. GL bro

Is it showing 'battery discharge' also?Just start from the beginning and have the battery tested, if low can it be charged to full.If its gone then new battery on and go into secret menu to see if it's a healthy charge,should be 14V running.Also what is the mileage.

A low battery with throw your electronics into a frenzy. Have to find out if the battery is low and why. Start the car and check charging voltage, as stated above should be above 13.5v depending on load. If it's charging good then have the battery checked. What year is your car? Usually around 5yrs is life expectancy on battery, I keep mine on a battery tender because I don't use the car all that often. Good luck bud!

Thanks for the info! Might just have to test the battery, and if the battery life is 5 years I’m due a change... year is 2013 LCI.

It’s not mentioning the discharge... mileage is 82k. Year is 2013.

Ok then still take it to battery shop and have them check the state of it, they'll have a reading on a dial after connecting prongs to the terminals to determine what it's present status is.

Yup sounds like battery could be your culprit, but have it checked first.

The MAF's throw that lean code, so if you have k&n filters then maybe some oil got into them. That would certainly throw a code, or the tune could possibly need to be adjusted for the additional inflow of air.

I would take care of the battery, clear codes and drive it. After a few days (depending on how much you drive the car), check the codes again and see what comes up.
