Dead battery / Jump / Steering Angle Error / Alarm Error

[Glaesemann]

Hi All,

2016 X5 E53 3.0 150,000 miles has been doing daily duty on my 100 mile daily commute with few issues. Many control arms replaced, but not much else for years.

Last week my daughter went out to the car to charge her phone while I sat and got my semi annual teeth cleaning. 50 minutes later I came out to a dead battery. She turned the key on but didn't start the car.

Got a AAA portable jump and have had nothing but problems since. I've been through this a few years ago with the trifecta, but that was cleared up with a battery replacement.

DCS is off with Carly showing an error code of 005BE00: Steering Angle Sensor - Internal Fault. DCS only, not trifecta.

The security alarm goes off unless I double click when locking.

Yesterday I replaced the battery with the exact same battery, neither of the errors are clearing.

I ran Carly code diagnoses and cleared all codes. The DCS will not clear, security alarm still going off.

Right after clearing codes I did the Steering Angle reset thing by turning steering wheel to lock left and then all the way to lock right and back to center. The DCS does not clear.

Since I suspect the alarm is related to angle positioning as is the steering, I wondered if there is a reset I have not done that would help?

Any and all feedback is welcome.

Many thanks,
Tim
