[QUOTE="jarance, post: 427888, member: 21"] You can check your battery by using the below procedure if you dont have a voltmeter. See TEST #9.0 listed below. [COLOR="Purple"] Instructions to access the hidden OBC functions: 1. Hold Trip Reset while turning ignition key to on position 2. OBC should show "Test" 3. Use Trip Reset to select function 19.0 that unlocks all the features 4. Wait for display to show "Off" 5. Depress Trip Reset for 1/4 second and release it 6. With no delay press Trip Reset several times to select one of the following function s BMW E46 On-Board Computer (OBC) Hidden Codes nr example description 1 Car Engine and cluster data 1.0 46nnn Chassis nr/VIN serial number (last 5 digits) 1.1 4nnn K-number 1.2 690236 Cluster Part # 1.3 045210 Coding (04)/diagnosis (52)/bus index (10) 1.4 1200 Week (12)/year of manufacture (2000) 1.5 09_160 Hardware (09) and software # (16.0) of cluster 1.6 Not used 1.7 04__44 CAN-version (04) KI-revision index (44) 2 (test) Cluster System Test - Activates the gauge drivers, indicators and LEDs to confirm function 3 SI Data 3.0 1098 Used fuel in liters since last SI (Service Inspection) 3.1 0231 Periodic inspection days; elapsed days (since last SI) 4 Momentary Consumption 4.0 0145+ Instant fuel consumption - 0145=14.5 liters/100km 4.1 0018 Instant fuel consumption - 0018=1.8 l/Hour 5 Distance Gone Consumption 5.0 082 Average mileage; 082=8.2 liters/100km 5.1 0536 Calc. km to refuel (momentary distance to go) 6 Fuel Level sensor inputs in liters 6.0 109330+ Fuel level averaged; Left half sensor input=10.9 liters; Right sensor input=33.0 liters 6.1 0439+ Total tank level averaged; vlgs 6.0: 10.9+33.0=43.9 liters 6.2 0442+ Indicated value (44.2) and tank phase 7 Temperature and Speed 7.0 021+ Coolant/Engine temperature (2.1C) 7.1 130 Ambient/Outside temperature - chg met 5 pts. 125/130/135 7.2 + Engine speed / Current RPMs 1/min 7.3 + Vehicle speed / Current Speed in km/hour 8 Input value in HEX form 8.0 1d0+ System voltage ADC-Value Hex code 8.1 26C33C+ ADC Values HG left/HG right 8.2 0000 ADC Value brake degradation sensor (000=o.k.) 8.3 18C ADC Value outside temperature 9 Battery 9.0 140 Battery Voltage - 140 = UB 14.0v[/COLOR] [/QUOTE]
