G30 (2017 - Current)
The next generation 5 Series, chassis code G30, arrives at dealers in February 2017. Looking like a scaled down 7 Series and riding on the CLAR platform, the new 5 Series will have a focus on lightweight and sporty performance. Engines options will come from BMW's new B family for the 530 and 540 and a turbocharged V8 for the M550i. Read more about the 2017 5 Series

Question Alarm on when locking doors

My 2019 540i is 2 weeks old. When I lock the car either with the key or the door handle the alarm goes on. I have to open and close the door and try locking a few times before the alarm does not go on. Any ideas what is wrong?

Alarm goes on and off when the car is locked. It's on page 100 of my manual. YMMV.

No. It is totally not normal for the alarm to go "on and off" when locking the car. If the lights and "chirp" option is set via iDrive, you will hear the locking whistle when the car is locked. Does the red light on the mirror flash quickly? This could indicate that it thinks a door, trunk or hood is open. Even then, the alarm should arm silently, with that open item ignored. Sounds like the OP needs a service call.

I had the same problem.Took it in for service and the adviser said they had seen that several times.They kept it for 2 or 3 days and it hasn't happened since.

As a clarification, the alarm does not go on and off it just goes on and stays on. Also the problem is intermittent so I need to let it become permanent before taking it in

By "going on", you mean the siren is sounding, like an intrusion occurred? It is totally intermittent? That would drive me crazy, not sure I would wait to take it in. Maybe they have a diagnostic or service bulletin.

The same thing keeps happening on my 2018 540i. Drives me crazy!

I thought I might be accidentally pressing a button on keys, but I would hold them in my hand to make sure nothing was pressed.

Generally I get out of car. Touch the handle lock, car beeps, walk 4 or 5 feet, alarm starts screaming. Then I fumble for my keys and unlock the doors to quiet the alarm.

It happens a few times a week. Any suggestions would be great!

Yes, it's broken - make an appointment with your dealer.

By any chance are you locking the car with a pet or human inside? It could be the interior motion sensor.

An easy way to check if it's the interior motion sensor would be to lock the car with the fob instead of the Comfort Access, then push the lock button on the fob a second time to disable the interior motion sensor. If that stops the false alarms, you know which sensor has gone bad. If not, it's likely another sensor has gone Tango Uniform, like the one that senses if your car is being jacked up.

One other possible culprit: These cars are so damn quiet, it's easy to exit the car with the engine running, particularly if you are on your cell phone or otherwise distracted. If you try to lock the doors while the motor is running, you will get several beeps of the horn. That doesn't quite fit your description of "the alarm goes on and stays on", but I'd at least rule it out before you take the car to the dealer.

Took the car to the dealer and he asked me if I had the Allstate "drive Wise" device plugged into the OBD port. I said yes. He told me that the devise is not compatible with the car and causes occasional alarms. Time will tell if that is the solution.

Not to change the post but a BMW 540i with a "drive wise" unit installed..*****! I did not expect to see that. A 540i is made for spirited driving; "drive wise" is made for Buick drivers.

I am curious what your experience has been with that unit installed. I would never do it but I have read some pretty unhappy user experiences.

Drive wise only penalizes you over 80 MPH. I can have spirited driving below that speed. In any event with the device removed I still get the 10% discount and drive any way I want. Same with my Genesis G80 the devise does not fit in the fuse box so I still get the discount.

I believe this has been reported before re devices from other insurance companies; anything connected to the OBD port is detected as an intrusion.

80mph for penalty is a bit ridiculous. On a recent trip NY-Boston-NY, there were many stretches with speed limits of 65, traffic flow at around 75 and a couple of instances where going over 80 was needed to pass safely and/or avoid a sticky situation. Driving safely is not the same as driving at the speed limit, and is more complicated. I would not have such a device in my car.

I'm going to try Quackbury's trick. I've scheduled a service for next week in case the internal motion sensor is bad.

I have child seats in back, but I try not to leave humans or pets back there.

I do have an Automatic plugged in to the OBD port, so that is probably it, though hoping for a motion sensor issue.

You're wasting your time by doing anything other than removing the device from the OBD port...

It won't be the internal sensor as that doesn't arm until a good few seconds after locking. This alarm is sounding immediately?

Hi,
I know this is kind of an old thread but wanted to add my two cents since we are experiencing very similar issues and to find out out how it turned out for the OP. We plugged in the Automatic Car tracker into the OBD port and went our merry way. Hours after when closing the car, the alarm was activated. Also we started receiving all sort of warnings like the check engine light, plus another warning about the drive train. Pretty scary. I told my husband to remove that thing from the car. It was removed but we are still receiving warnings about the drive train, the check engine light is on even though I checked the fuel cap. This is a 2019 540i, that we bought used, last week with 10k miles. I think a trip to service is required. We used this Automatic device on our previous Lexus 2015 without issues! I know I can't compare both cars both we thought it was ok to use it in our Bimmer. Ugh!

Edited to add: The Automatic Car Tracker website says that 2019 540i is a compatible car

The check engine light could be 100 different things besides a lose gas cap. And if you don't have an OBDII scanner that can retrieve the code(s)...just stop by an AutoZone or similar auto Simi tore to have them pull the code (it's free).

Once you have the 5 digit DTC (diagnostic trouble code)...type "BMW OBD II PXXXX" { where x=the actual code nbr}. The generic OBDII codes have been in effect since 1996...so most of them have been discussed that a google search will bring up results that may provide info/solutions/causes/resolutions etc.

Again no need to wonder what sensor in your emissions system set the code when it can easily be retrieved. ..even if you're taking it in to the dealer. It's good to know why and you can point them in the right direction.

Thanks QSilver7 for the very helpful information about the check engine light and what it means. At this moment is back to off. All these warnings started happening after we put that Automatic GPS car tracker in the OBD port so I believe this caused some havoc in the car system that started by triggering the alarm when closing the car. I will definitely take it to the nearest BMW service on Tuesday or Wednesday. Tomorrow is closed due to the holiday and Tuesday due to the hurricane Dorian. So the Bimmer will have to wait. Thanks
