Need advice: clock and date needs resetting

[theboysact]

Hi all,

My clock and date prompts me to set every time i come back to the car and start engine
Got this problem since yesterday
After a reasonable distance drive, parked the car for one hour, prompts me to set time again when i restart the engine

What could be the problem?

High chance battery but my cranking and radio all ok leh

Maybe should just test the battery then see how .....

After that check IBS configuration.

The IBS config contains settings for your battery. You need tools to access it - ask a workshop to check for you.

First test the ibs sensor with Rheingold and after that test your battery.

80% is the battery. Changed mine when it happened and problem solved.

Someone just changed battery for $190:
"I just changed to Amaron Pro 100AH 900CCA for BMW7-Series. I paid $190nett. Free installation."
