I attempted to start my 2011 E91 320d N47 at my mother-in-law's residence last night. The dashboard lights were functional; however, when pressing the start button, there was no response. I did not see any clicking sound, just weak, typical sounds emanating from behind the dashboard, but nothing more occurred.
She drove home in her Vauxhall Agila.
Returning this morning with the spare key, the code reader, and other tools.
It is at this moment that one reflects on the preceding 2 to 3 weeks, recalling that on two occasions the device failed to activate. Initially, it was attributed to insufficient key insertion, since reinserting the key resulted in successful ignition. However, this time, it did not start at all.
The battery is functioning properly; nevertheless, I will inspect the positive lines at their departure from the boot and ensure the battery box is dry, as well as scan for diagnostic codes.
Is there anything further I should attempt while I am there before I provide the codes?
Greetings, team!
