Question about 2001 BMW Z3

1 Answer

Z3 fuel gauge twitch

I have a 2001 BMW Z3 2.5i. The fuel gauge will sporadically not function and it points to empty.

It will:
(a) occasionally flip back on it's own to where the fuel level is, or
(b) if it doesn't flip back, usually after I park it and then go to use my car again, the gauge works fine (until it acts up again).

One thing that I coincidently noticed one day is that I happened to press on the tripmeter switch and it made the fuel gauge (which was poiting to empty) spring back to where it should have been.

Could it be that there is a loose connection?
How can I remove the cluster to get behinfd it and check it out?
What do I need to do once I hacve the cluster out?

Thanks!

Do not top off tank when fueling. Had this problem and realized that it occured when I topped up after the pump shut off. No problem since. Feel that when topping up, you overfill the tank and fuel gets in the vent line and charcoal filter which somehow affects the fuel gauge. I have a 99 Z3 coupe.

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 1999 BMW Z3 will crank & will not start.I used Bavarian code reader code A9 & code 44 show up.What do I need to replace?


an engine needs fuel, compression, and spark to go....check those things first. Put a fuel pressure gauge on the rail, then remove a plug and ground it to see if it sparks, lastly, run a compression check on it. make sure the cam is turning as well.

Check your fuse boxes, usually one under the hood and one under the steering wheel, might have just blown a fuze somewhere along the line.

Fuel gauge stuck on empty bmw compac 325ti 2001 model


There are a couple of things it can be, either there is a bad gauge, or the float in the gas tank is sticking. If the gauge is good you will have to drop the gas tank and repair the float. hope this helps

I have a 1997 BMW Z3 roadster. I filled my tank drrove a mile and the gas gauge falls back to empty. What could possibly be the problem


Could be a short in a wire from your fuel gauge to the fuel tank where the actual fuel gauge sending unit is probably located.
