E39 (1997 - 2003)
The BMW 5-Series (E39 chassis) was introduced in the United States as a 1997 model year car and lasted until the 2004 when the E60 chassis was released. The United States saw several variations including the 525i, 528i, 530i and 540i. -- View the E39 Wiki

Silence!

It was definitely the siren batteries. Once removed, the battery has not died once nor have the lights been seen flashing. I am once again gaining confidence that I can go to my car and it will actually start versus being met with a dead battery.

I have received the batteries and will wire them into the siren, reassemble it and install when I get time; I'll try to post pics to help explain.

Hope no one else has to go though this, but if they do, at least there will be a post to help them.

That is horrible. For my car, it was a weak car battery that caused it.
Once I got a new AutoZone battery, everything was back to normal.

I have my car alarm going on and on too. I've read an article about car alarms and code grabbers but I don't believe that someone would try to unlock my car with a grabber. Is it really possible?

Unfreaken Beleivable

I simply can not believe this POS car.

AFTER disconnecting the interior sensor, hood sensor and completely removing the siren assembly...a workmate comes to me yesterday and asks "Are you car's lights supposed to be flashing?.

Evidently there is still something activating the alarm system but I have no idea what it could be. I've read online from people stating their car had dirty metal contacts on the doors but when I looked at the entire door perimeter I did not see any.

Can anyone on this site list all of the sensors that make up the alarm system on a 528it?

Begin rant...I am so sick of this car and the myriad of problems associated with owning a BMW. Between the crap gas mileage, outrageous maintenance fees and parts prices what exactly is the allure to owning these cars? I just don't see it. Problem now is that this POS has depreciated 70% in 4 years so it's about worthless to trade in on a decent reliable car. Rant over... I now feel slightly better.

I reiterate this.
How old is your battery?
Mine was only 2 years old.
Replace the battery.

I reiterate, I had the complete battery and charging system just checked...all good (battery is one year old).

No one has anything telling where the alarm sensors are? (Hood, siren, interior roof sensors have all been taken out of the picture).

Lots of discussion on it here:

Hood Sensor / Alarm issue

Try pulling the plug. See if the alarm still goes off randomly. This doesn't affect your main door/interior alarm sensors in any way.
this is what caused my alarm to go off when i first bought my car. i just unplugged it too. hasn't gone off randomly since then

  • Check if the battery is loose.
  • Replace the battery with a new one.
  • Detach hood sensor.
  • Check door latches/sensors
  • Disable motion sensor by press key locking button twice
  • Detach inside motion sensor
  • Unplug fuse #48 in trunk
Based on this thread today, we can add a check for the fuel filler door being ajar due to a non-standard (too large) gas cap:

In reply to: "I've read online from people stating their car had dirty metal contacts on the doors but when I looked at the entire door perimeter I did not see any."

The door switches are part of the assembly the door hooks onto when it closes. Look closely and feel, there's a small bump that clicks when pushed in. All 4 doors.

By way of cross reference, an interesting thread was opened yesterday which has a lot of useful information in it ...

So how do I turn this of when i dont have any battery on my keys?

They all are independent systems that work in tandem or conjunction with each other. EWS doesn't require the battery inside the key...it is self powered through induction...and a 125 KHz AM signal that is sent from the EWS control module to the Ring Antenna around the ignition. EWS though, does send a signal to the GM that does tell it that the correct EWS key has been used and this can release the UNLOCK (double-lock) feature as well as turn off the alarm siren if the emergency deactivation is required.

DWA & FZV features of the key require the battery to transmit the 315 MHz (No America) or 433 MHz (Europe) radio frequency to the receiver in the C pillar, which then sends a signal to the GM. From there data is sent to the DWA monitors (sensor) and to the central locking system actuators.

Back to the flashing lights only...that is usually a sign of low battery voltage. And when you wrote that the car has sat for a while with the battery disconnected...you don't mention if the battery was kept on a charger or if you recharged it when you put it back in the car.

If you've unlocked the OBC...you can run TEST 9 and see what the battery voltage is...or if you have a meter...test the battery's voltage . If a battery with no surface charge is reading at 11.89 volts...then it is at 0% state of charge...it may have enough juice to run some electronics but you may begin to see odd electrical gremlins as the voltage continues to drop.

Give your battery a good long charge at approx 2 amps for about 20 hours...or 6-10 amps at approx 10-15 hours.

Here's some info below on the DWA system...hopefully it will help some forum members understand the difference between EWS, DWA, and FZV:

Even if some of the docs have a model name in it (like X5)...if it's about a BMW system and not model specific...it generally will cover the other BMW models that are of the same generation.

Happy reading.

So as to leverage Q's wonderful information, I reference this thread today ...

Was the motion sensor optional along with a siren? And is it pre-wired for a siren and motion sensor?

The IMS (int motion sensot) may have been removed by a previos owner due to false triggering....when you remove the cover is the wiring there? The audible arm/disarm chirps can be programmed off or on as wellas the viual arm/disarm alerts.

The alarm siren can also be disconnected (or disabled) and its location is behind the wheel well liner of the rear right wheel.








(again, the alarm's audible & visual alerts can be programmed off/on by your dealer or if you have aftermarket software/hardware)
