2002 Mini Cooper, base model, automatic transmission
Hoping that someone on forum can point me in right direction to fix speedometer back lights and tachometer issues
Current Symptoms / issues:
· No Speedometer back lights (fuel gauge, mileage, seatbelt lights all function)
· Tachometer (fixed at 1000), lights and engine display lights on tach do not function
· Dash light dimmer switch has never seemed to work properly
· Brightness of clock varies and is never really bright.
· No power to fuse 5
· Volts from Instrument Control Cluster only sending 5 volts to tach
· No communication with diagnostic buss
· Stereo, A/C, windows, locks, and heated seats, wipers, cruise, etc all function properly
Lights on speedo went out and Tach just suddenly stopped working. At the same time:
· Battery kept discharging
· Local shop could not find source of drain / short
o Some connectors showed signs of corrosion – fixed and cleaned
Warranty / Recall & Work Performed:
· Electronic power steering pump and fan were determined to be the issue of battery drain. Replaced by mini dealer under recently announced warranty recall
· New battery installed
· New BCU installed
The BMW repair shop technician thinks there is a short someone in system causing these issues, possibly another blown control module. Advice anyone?
