SOURCE: Need location of fuel pump on a 1992 BMW 525i straight six engine

The fuel pump is located under the back seat on the passenger side. You will find an access cover and will need to remove the screws. You should be able to listen for the pump while someone cranks the car. Also I believe there is a large green w/ blue trace wire and an equally large brown wire at the connector. Check for battery voltage across the two wires. The fuse for the pump should be in the fuse panel under the hood.

SOURCE: BMW Z3 WRONG UNLOCK RADIO CODE HOW TO GET THE RIGHT ONE

If the radio is displaying code wait, or wait, then the ignition and radio must remain on for 1hour. I would contact a dealer within the USA and provide them with your radio serial number. The serial number can be displayed in the radio by pressing and holding down the "M" button while turning on the ignition.

SOURCE: 1999 BMW Z3 radio code

I have same problem need to get the serial number off of the back of the radio and the vin# and give that info to the dealer and he will have the code. If code still does not work ask for a different code since they installed radios from different manufacturers.

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...

Why is my1997 bmw Z3 1.9 start rough for 2min then is ok


The EGR valve opens when the engine is warming up, which allows exhaust to enter the intake manifold. This is essentially "extra air" coming into the engine. The engine has an "idle speed control" function, which is either a solenoid or small stepper motor connected to a valve that allows a controlled amount of air to "sneak" by the throttle plate in the throttle body. Fundamentally, it is the amount of air entering a fuel injected engine that controls engine RPM. A defective idle speed control ("ISC) motor or solenoid can cause the problem you stated. (I do not know which type is used in your BMW.) Often, a check engine light will illuminate of the engine computer cannot adequately regualte engine idle speed.

Bmw z3 1999 will not crank


The problem sounds like the battery has run down. Even though the ignition is off, things like clocks and the radio draw small amounts of power to retain their settings, and the instrument cluster doesn't draw as much power as the starter. It usually takes about a month or so to drain the battery. Try jump starting the car, or put it on a battery charger for a while.

Idles up and down on cold start


Probably a vacuum leak, but wandering idle can also be caused by cracks in the intake air tube between the mass airflow sensor and the throttle body, or by gunk in the idle air control valve.

How to reset brake light after changing pads.


Hi Peters6709,
Sorry to tell you, but you need to replace the pad-wear sensors as well. They are the little trapezoid pieces that hang inside the tops of the inside pads. They should run about $10 each. Once replaced, disconnect the battery completely for about 10 minutes, if you have a stock radio keep the code handy.

Next time check the pads every 10-12K miles. I have been running the SAME pad wear sensors on my Z3 for the past 2 pad changes now after making the same mistake the first time.

Best of luck!

My z3 starting problem


i would say its a dead (flat) battery. if its more than 4 or 5 years old, it might be time to replace it.

try jumping it with another vehicle. if it jump starts, then replace the battery.

if its a newer battery (less than 4 years old), then something is draining the battery or the alternator is not recharging it.
