    BMW E46 ZHP DIY and Preventative maintenance doityourself

    I just wanted to save this somewhere. It's a work in progress.

    S54 broken down


    The wiki does a fairly good job at laying out the problem area's....

    http://www.bimmerfest.com/wiki/index...ook_out_for.3F

    Additionally....

    Please read this thread prior to proceeding to work on your car. Ask if you have questions about properly supporting car.

    1. Keep up with Service I and service II inspections. Early preventative maintenance is key at maintaining longevity.

    http://www.linquist.net/motorsports/bmw/service

    2. Change oil with BMW LL-01 approved oil every 7000-9000 miles. Intake filter and in cabin air filter every 15000 miles.

    FYI...WIX oil filters are not OE/OEM and one should go with Mahle or Mann...easy to find, too.

    3. Suspensions on E46 seem ok for the first 100,000 miles...but after that most swap out, due to suspension getting tired and fatigued. This also depends on driving style and whether or not you're lowered. Additionally make sure your tires and alignments are up to stuff, as driveability is really affected by these two maintenance items.

    5. FSR (Final stage resistor) for the blower motor seems to fail regularly. This will be indicated by blower motor acting erradically

    6. Batteries last 5-7 years. A lot of info in post #27 and #28.

    7. Tranny and diff fluid should be swapped no later than 100,000 miles as BMW re-defined "Lifetime" as 100,000 miles. After that...I think most recommend around 30,000 miles to be safe.

    9. Lower intake boot developes tears/cracks due to design and high temperature's.

    http://www.zhpmafia.com/forums/showt...ISA-inspection



    10. ICV does become dirty and needs to be cleaned with carb cleaner. Inspect upper/lower intake boot, and inspect DISA when doing this.





    11. DISA valve failure due to design flaw.

    http://www.bimmerfest.com/forums/sho...d.php?t=323335

    11.5. DISA o-rings and DISA repair kit

    http://germanautosolutions.com/DISA_O-Rings.html

    http://www.germanautosolutions.com/D...epair_Kit.html



    The resonance system provides increased engine torque at low RPM, as well as additional power at high RPM. Both of these features are obtained by using a resonance flap (in the intake manifold) controlled by the ECM.

    During the low to mid range rpm, the resonance flap is closed (i.e., the flap is actuated by alternator voltage such that it is held vertically against spring tension). This produces a long/single intake tube for velocity, which increases engine torque.

    During mid range to high rpm, the resonance flap is open (i.e, the control voltage is reduced to zero which causes the flap to return to the horizontal rest position due to spring tension) . This allows the intake air to pull through both resonance tubes, providing the air volume necessary for additional power at the upper RPM range.

    When the flap is closed, this creates another "dynamic" effect. For example, as the intake air is flowing into cylinder #1, the intake valves will close. This creates a "roadblock" for the in rushing air. The air flow will stop and expand back (resonance wave back pulse) with the in rushing air to cylinder #5. The resonance "wave", along with the intake velocity, enhances cylinder filling.

    The ECM controls a (magnetic) solenoid valve for resonance flap activation. At speeds below 3750 RPM, the solenoid valve is energized (with alternator voltage at the harness connector) and vacuum supplied from an accumulator closes the resonance flap (where the vacuum accumulator is apparently a one-way flap valve with a 1/16" entrance hole in the side of the DISA) . This channels the intake air through one resonance tube, but increases the intake velocity.

    When the engine speed is greater than 4100 RPM (which varies slightly - temperature influenced), the solenoid is de-energized (i.e., the harness control signal goes from ~13.8 volts DC to zero volts DC) The resonance flap is sprung open (by spring tension), allowing flow through both resonance tubes, increasing volume.











    12. VANOS software replacement due to BMW using incorrect material for seals on VANOS pistons. (BUNA-N vice Viton)

    I would have 1qt of whatever oil you use, and permatex to go along with the below.

    13. Do plugs when you do VANOS. usually good for around 100,000 miles. Only do coils if indicated by misfires and OBDII codes.




    14. CPS (Camshaft Position Sensor) failure seems pretty regular.

    27. Key Re-Initialization

    Get in and close all doors.
    Turn on the ignition and turn off quickly. (No more than 5 seconds) to start the process. Next action must take place within 30 seconds.
    Remove the 1st key.
    Hold the key up near your left shoulder (this is so it is closer to the remote reciever antenna - someone else suggested this).
    Hold down the unlock button (which is button 1 on my key) and press the lock button 3 times (center button on my key). Release the unlock button and the doors lock which confirms the operation.
    Quickly repeat steps 4 & 5 for key #2 etc.
    If it does not work, try doing the keys in opposite order. Key 2 then key1, vs 1 then 2.

    Remember to alternate your keys from time to time so that you keep the batteries in both charged. Some have found success with placing the key into a rechargeable toothbrush charger overnight as well.

    Another thing you can do is to replace the battery! It's not officially possible (or recommended) for the new key design (2000+) but it can be done.

    40. E46 M3 rear diff you will need the following.

    Rear subframe
    Diff housing
    M3 sway bar (M3 diff will hit your stock sway bar)
    M3 half shafts
    M3 drive shaft (are you 5 or 6 speed?)
    M3 abs sensors

    Basically I would go with Quaife at this point if it was me.

    Dont the steptronic ZHP have a 3.64 ratio? That is another option if you don't want to spend a ton.

    If you can source the right diff out of a ZHP auto or step and do the labor yourself you could do it for a couple hundred bucks. Don't be scared, diffs aren't hard until you start trying to set ring and pinion gears yourself. Which you don't have to do.

    Is a rear diff swap worth the money? IMHO one of the best damn mods you can do!!!" Cody Stevensen

    Vehicle speed = Engine RPM * Tire Diameter / (transmission gear ratio * diff ratio) --- convert any units as necessary.

    Solving for diff ratio, you get

    diff_ratio = RPM * circumference / (speed * trans_ratio) -- convert all

    So say you're at 3500 RPM in 4th gear (auto) when going 70

    diff_ratio = 3400 rev/min * 25pi inch/rev / (70mi/hr * 1056 (in*hr/min*mi) * 1)
    diff_ratio = 3.61

    It won't have battery and ignition detect like a cable meant for BMWs, but that doesn't really matter. If that bugs you, look for a "D-CAN" cable.

    Then find DavidMc's 4shared folder (there's a link and password somewhere in the diagnostics section of bimmerforums) and download EDIABAS 6.4.3 and EasyDIS v44. There are guides on how to set all the software up.
    --------------------------------------------------

    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.

    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
    Sub-Tests
    L-ON---
    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
    Sub-Tests:

    TEST 05. - Distance Gone Consumptions
    Sub-Tests:
    0195 5.0 = 19.5 liters/100km
    226 5.1 = momentary distance to go (226km)

    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).

    Sub-Tests:
    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.
