3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
My 2003 BMW 325i cluster displays fine (mileage, clock, etc.). But I cannot access any of the functions (such as to change the time or scroll through the menu). I got this BMW used and the manual mentions accessing the functions by a button on the end of the turn signal. There is no button on the turn signal. There are buttons coming out from the cluster display that I think should enable access to the computer functions, but nothing happens when I push or turn them. I had one mechanic tell me that it was the onboard computer that needs to be replaced for about $900, but I don't know if I trust him. Any ideas what's wrong? Thanks.
Incase no one knows here's how to do it.
Tests 1-2 are unlocked. Tests 1.2, 1.2 etc are known as sub-tests. Tests 3-21 are locked but Test 19 is the unlock function for accessing the displays.This should work with your vehicle.
TEST 01. - Vehicle specific data including:
12345 1.0 = VIN
7504 1.1 = Body number
690151 6_1.2 = Part number of cluster
039000 1.3 = Coding/Diagnosis/Bus Index
1102 1.4 = Manufacturing date (calender week/year)
06_110 1.5 = Hardware/software # of cluster (HW:06, SW:110)
1E5_06 3_1.6 = injection status, number of cylinders, engine factor
TEST 19. LOCK/UNLOCK
L-OFF 19.0 =
Displays changes from "L-ON" to "L-OFF" every second. To unlock test functions, press the cluster button immediately when it changes to "L-OFF". Tests are automatically locked when exiting test functions.
TEST 02. - Cluster System Test - activates the gauge drivers, indicators and LEDs to confirm function.
TEST 03. - SI Data
1500 3.0 - Liters
0 3.1 - Periodic inspection days (not applicable for US)
TEST 04. - Momentary Consumption
0267 4.0 = 26.7 liters/1000km
0073 4.1 = 7.3 liters per hour
TEST 05. - Distance Gone Consumptions
0195 5.0 = 19.5 liters/100km
226 5.1 = momentary distance to go (226km)
TEST 06. - Fuel level sensor inputs in liters
237415 6.0 = Fuel level aveg. *LH sensor input = 23.7 liters
*RH sensor input = 41.5 liters
0652 6.1 = Total tank level average = 65.2 liters
0667 1_6.2 = indicated value and tank phase *1 = both sensors OK
*2 = one sensor fault
*3 = implausible input
TEST 13 - GONG Test
Gong 13.0 = Activate gon by pressing buttong (gong response is delayed)
TEST 14. - fault memory (NOT FOR DIAGNOSIS)
TEST 15 to 18
TEST 20. - Averg. fuel consumption - correction factor.
The factor follows previous systems, with adjustment range of 750 - 1250. The adjustment method is new for the base cluster. If adjustment is necessary, enter into test 20 using the cluster button.
The correction factor number is changed by using the sub-tests for the "ones, tens, and hundreds of the correction factor number. The digits will automatically scroll through 0-9 within each group (ones, tens, hundreds).
XXX9 20.0 = Press the button when the correct "ones" position is attained.
XX5X 20.1 = Press the button when the correct "tens" position is attained.
12XX 20.2 = Press the button when the correct "hundreds" position is attained.
Thanks for the quick response, but no luck. I did what you said but it does nothing different from when I ordinarily start the car. The first thing that happens is that the miles to service displays for a moment, then it goes to a normal display of total miles, trip miles, and clock. It stays on that display no matter what I try. Pressing either of the two buttons on the cluster display does nothing to change the display. Any more ideas? Could it have anything to do with a defective DME? That's what the mechanic said.
No, It has to be programmed, however I think your problem lies here, Models before 1989 have the code plug located inside the brown connector of the cluster, later models have it plugged in the backside of the mother board. The code-plug (at times) could be the cause of failure for some of the functions of the instrument cluster, and it is only available for purchase via authorized BMW retailers. For a successful bench test of the instrument cluster, it is necessary for the customer to supply the code-plug.

I stepped in a plate of Pasta the other day - now I have to worry about my Carbonara footprint!
OK, it turns out that my problem was diagnosed as a defective instrument cluster, not the on-board computer as I had feared. So it cost $175 for a repair/replace of the instrument cluster. It sat idle for a couple months before I finally got around to testing it, and I did go through some of the test functions, including #2 where all the lights come on and the indicators move. Now here's my next dumb question. The user manual that I have talks about accessing the instrument cluster functions by depressing the button on the turn signal lever. My turn signal lever has no such button as depicted in the user manual. I do have the two buttons on the dash board, but all I can do is reset the odometer, change the clock to PM, or change the clock to 24 HR mode. Pressing those buttons gives me no other functions (like outside temperature, etc.). What am I missing? Thanks

It sounds daft saying it, but you are missing the button on the end of the turn signal lever ! Really, the On Board Computer is there, but some models were not supplied with the control for it. You have to buy a new turn signal lever with that switch button fitted, (picture in instruction book), then you will get those functions, MPG, miles left until next fuel fill, outside temperature, etc. After fitting the new switch, it will have to be activated by a BMW dealer.
The Hidden Functions have a knack to getting them. You have to go to 19 to unlock all of them. Until you unlock them you only get tests 1 and 2. Press and hold trip reset and turn key to first position. Display will show "test" and "1". Press trip reset to go to test 19. Wait for display to show "off". Press trip reset for 1/4 second, and release. then quickly press trip reset again to access tests 3 to 21. Details are described by Marti5 in post 3. Stop pressing when you reach the test you want. Then press the time change to get to the sub-menus. If it goes back to normal milage and clock display, you have come out of the test mode, and have to turn the key off and start again to get back into it.

Hi, everyone. Just joined so I can post - I'm helping a friend with a couple of issues on his 2002 330Ci and I can't get the tests to unlock.
I've followed the odometer/key instructions and I can access Menu 1 submenus 1.1 to 1.7 but I can't get to any other menu - it just wraps back round to 1.0 again.
