2001 BMW 540i V8 Four Wheel Drive Automatic 93,000 miles
My 2 years-old battery needs recharging daily. I took the car to the Sears battery shop for testin and they confirmed that the battery and alternator are working fine. They poointed to a possible battery drain or leak.
For some time, I have noticed that the locking mechanism in the front passenger door clicks every 20 seconds, all the time, whether the doors are locked or not, and whether the engtine is running on or not.
As I read on this board a similar problem encountered
(See "2001 bmw-530-battery-needs-charging" ,,,http://www.2carpros.com/forum/2001-bmw-530-battery-needs-charging-vt210460.html)
I concluded that that is the possible source of the leak.
Question: how can I confirm that the passenger door locking mechanism is indeed the source of the leak?
And if so, should I remove and replace the passenger Door Lock Control Unit to fix the problem?
Any other solution?
have the same problem?
