Dead Battery on 1.1.18 beta 4 #98

Hi Ted,

I've parked the car for 2 days and the battery was dead at ~4V. Recharging it at the moment.

Battery and Generator are OEM and from 2021.

In addition:

I've coded my LCM to confirm opening and closing of the car via the signal lights - and noticed that the un-lock doesn't get confirmed anymore only the locking (or the other way round). Not sure if this Bluebus related.

Running a BM54, MK4, 16:9 setup in my 2000 E38.

Many thanks, Tim

@dertimaushh

The unlock light issue is BlueBus related and there is a fix for it. Can you temporarily remove the BlueBus from the car and see if the battery drain persists? If you shoot me an email I'll send you the latest bets to fix the unlock issue.

Thanks- the light issue is fixed with 1.1.18 rc7.

But now coolant temp doesn't work anymore.

Battery seems to be fine for now.

BR, Tim

I had the battery issue, too.

Mine was related to the telephone module. I removed the Motorola-Unit in the trunk in order to connect the BlueBus adapter cable, not knowing that the front module still was "alive". This permanently held the bus alive which - you guess it - drained the battery. The front module can be disconnected under the handbrake-cover (if you have small hands) or you remove the left cover (held by one screw in the pedal region) and then disconnect the plug.

Is this true? This would effect everyone who has the phone and got a Bluebus, that's very important information if so. I'm also researching a battery problem so I'll see if I can find the connector.
