Hello everyone - new forum member here looking for help.

I have a 2005 530d, I am the second owner, FSH, 60k miles.

Car runs reliably and always starts on the button.. until yesterday it was due to go in for a service and went to start it up and it was dead - typical!

Console/radio/dash signals coming on but car will not start. No turnover, no clicking, nothing. Console/radio/dash signal go off and come on again etc.

Have tried to jump start and tried charging battery but makes no difference.

I have noticed there is a high pitch electronic type noise/buzz/ring that is coming from around the engine bay, and even after locking the car and 30mins + the green led for window lock is not turning off.

I am wondering if a relay/switch is stuck on and the car is not shutting down all systems and there is a battery drain..?

Can you help?

Is there a way to diagnose/fix myself easily?

Any help highly appreciated as am stuck without a family car!

Thanks in advance - Ronnie
