Greetings everyone,
I possess a 2003 E320 CDI W211, and I am experiencing the following problems:
Initial instance, battery depletion during the nite
When the ignition is activated, a particular light illuminates regardless of the light switch's setting; subsequently, if I switch the light control to auto or on, the driver's side remains illuminated while all other lights flicker, including the interior dome lights, footwell lights, and steering wheel control lights, which is quite bothersome.
I continually experience the battery convenience features being disabled, only to revert to enabled intermittently.
The blower activates and deactivates in sync with the battery convenience alert.
The parking sensors are malfunctioning.
The rear windscreen wiper is inoperative.
When I press the button to access the area of the CD changer, it fails to open; I suspect I do not possess a CD changer, yet the door remains unresponsive.
My radio was nonfunctional until I performed a fibre optic bypass on the module in the trunk; it now operates perfectly.
No indication of a red battery light or any alerts! The crimson battery indicator illuminated briefly while I had the heater at maximum, wipers activated, radio playing, and lights engaged.
New primary battery with charging at 13.8/14 volts during operation.
Could you provide any suggestions? I appreciate it.
