My 1999 bmw z3 will crank but will not start , code A9 & 44 shows up , air pump keeps running when ignition is on & drains the battery out.engine light & EML light comes on.


Not sure on this one.....if it's "drive by wire" that means the accelerator pedal is connected to the intake electronically, and that may be where the A9 code comes from. Saturns are drive by wire and it's a common failure point for them. spark, compression and gas is all you need for the engine to run. you can put a fuel pressure gauge on the rail to determine fuel, assume that the compression is good, and pull a spark plug and ground it while cranking to see if gets a spark...

My bmw 730 is giving error passenger airbag fault, there doesn't seems to be any visible malfunctions. can this be fixed manually or do i need to see a bwm repair shop?


Hi there,

Your Airbag system is monitored by your vehicle's on-board diagnostic (OBDII) system. Although you may not see any visible defect, the system has identified a possible electrical or sensor fault and will have stored the appropriate fault code/s in its memory.

As your Airbag system is a critical safety feature, you will need to have these codes extracted by your local BMW dealership. The codes will immediately identify which component is at fault.

Hope this helps...

BMW 1 SERIES ORANGE ENGINE MANAGEMENT LIGHT COMMING ON OCCAISONALLY,ALSO CAR SEEMS TO STUTTER WHEN EXCELLERATING. CAN ANYONE GIVE ME POINTERS PLEASE


Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

When driving car turns off


The engine in this car is controlled by a computer called the PCM, when this type of event occurs the computer will sense the failure and record a fault code in it memory. What you must do now is have the computer scanned for the fault codes in its memory and then the proper pin point diagnostic tests run by a trained technician to determine what is failing, this can be a sensor like the crankshaft position sensor or other faults in the ignition control system or fuel control system..

Abs light is on trany strock on secound gear


If the second gear problem happened just as the ABS lamp came on.....Car is in Limp Mode.

ABS system has set likely a code about safety...ie" Brake system failure..... although 3rd gear is usual default.

You must scan for codes and remedy the fault/s.

Have replaced ABS module on bmw 525 E39 and ABS now ok, but the ASC lamp will not go off on the dash and fault code 23 (incorrect coding) will not clear from system? Everyone told us the ABS ecu does not...


ABS/ASC module is faulty
CLASSIC ABS FAILURE SYMPTOMS:
- Most of the time, the problem is the ABS module or one of the 4 wheel speed sensors (& sometimes the brake pressure sensor)
- In my 2002 BMW E39 DSC, three orange (warning) cluster display lights lit, ABS, Brake, & DSC
- The 3 warning lights reset when the ignition is turned off, only to repeatedly reappear within minutes of normal driving
- The fault is often intermittent leading you to falsely believe you've resolved the problem (proper diagnosis is important)
- Sometimes the fault only appears when the engine is hot; other times only at speeds over 40 mph
- Carsoft may erroneously show a rear speed sensor failure; but just replacing the speed sensor may make no difference.
- All the work is in correct diagnosis of the problem; parts replacement is trivial (from 1 to six bolts in a few minutes)
- Hence, this BMW E39 ABS 3-warning light DIY will concentrate on understanding and diagnosis of the problem
