As You say I'd reset them and see what happens. Run it for a couple of days and then check back.

Exactly the right question. I have a Canadian spec Z4, and if the check engine symbol OP is talking about looks like a car lifted on a hoist, then indeed our Z4's failing battery caused this symbol to appear on the dash. It would initially come up when the battery did not have enough charge, during colder days, and driving the car for 30-40 kms would clear the fault symbol. Eventually, the battery failed, and once it was replaced, the symbol did not re-appear.

Good luck to OP.

Good question on the battery. That happened on the 2009 Z4 I use to own. I started getting codes and it turned out to be the battery, just weren't any emissions codes at the time. If it happens again I will check it

From a google search

Instrument cluster Fault Code: 00A559, Fault Explanation: :KL30g f shutdown Associated with Battery Drain

Fault Code: 009CCE Fault Explanation: Drive passenger side mirror broke / battery deep discharge Another Battery indication

Fault Code: 00A8B6
Fault Explanation: :Left brake light is defective, PL3 from 07.14 and
SA5A1: LED daytime running lights broken, PL3 from 07.14 and
SA896: daytime running lights Halogen left defective
none of these are broken or defective, is the 7.14 supposed to be a stored date?

Phone / Telefon Fault Code: 00D690 Fault Explanation: :MOST: ring break / Ring break diagnosis wasSearch says often caused by fiber optic cable issue. I am not using the center console phone thing and have had no issues with my BT connection

Central info display Fault Code: 00A47E, Fault Explanation: :Flap error: Blockade / Hardware Error: Internal voltage supply defectiveAnother voltage item, could be battery or voltage reg. I havent had any issues with the flap opening or closing

Airbag Fault Code: 0093C3 Fault Explanation: :- passenger seat mat
Fault Code: 009439 Fault Explanation: :CIS mat CIS error
heating wire interruption / CIS mat - CIS error 6 Search shows sometimes the passenger seat mat under seat material gets cracked breaking connection. I haven't had the seat heater on. Do I care about this one?

Fault Code: 002F83 Fault Explanation: time counter combi - time
counter DME, comparison
Fault Code: 002F81 Fault Explanation: - time counter DME, comparison
These have to do with engine turn on and off times. I have pressed the start button and started it when I was trying to shut the entuire car off and quickly shut it off. Wonder if that could be the cause here

Fault Code: 002D2A Fault Explanation: Differential pressure sensor, intake manifold: Adaptation
Fault Code: 002D29 Fault Explanation: Differential pressure sensor, intake manifold:Plausibility
Both have to do with the MAP sensor and pressure in the manifold

Battery is a maintenance item - just change it if over 4 yrs old. Price of admission and the cause of most weird errors...

A friend of mine is a service adviser at a BMW Dealer he said these codes are for the pressure sensors in the intake manifold. Those are used for the valvetronic to make sure there is enough vacuum for the crankcase gases. Usually when those faults occur, the sensor has failed.

Since I have the PCV recall still open, he suggested I have them look at it when I bring it in.

I know the the vent hose goes from the back of the valve cover to under the intake,but how easy is it to get into the intake manifold? How much disassembly to get to these sensors?

Combination of the battery and a new manifold sensor cleared the faults
