My M2 Is Setting Off Alarms
It's happened twice now. I start my M2, in the underground parking lot where I keep it, and it trips the car alarm of another vehicle.
I should hasten to add that, when I start my M2, I don't rev it much at all. Also, my 2015 X3, parked right next to my M2, has never caused this phenomenon during hundreds of starts. To be fair, though, the M2 is much "boomier" when first started. The first time it happened, about a week ago, the other vehicle was pretty far away, maybe 10 spaces down. It was a sedan, but I'm not sure what make/model. Today, when it happened, the other vehicle (a Porsche Cayenne) was 3 slots away. I felt a little guilty driving off with the Cayenne angrily honking its horn and flashing all its lights. Has this happened to anyone else? -scr Edited to add: I'm running the stock exhaust system.

The stock exhaust sounds rather loud when starting the car (even in comfort)... I don't necessary like the attention it creates. But is some sort of sportscar so it is forgiven.

Yeah this is almost a twice a week problem for me and I feel so bad for my neighbors I actually apologized to most of them already whenever I end up catching them pulling in or out at the some time I am lol. Thank goddd they're all really cool and don't mind it at all. I never set their alarms off cause it's outdoor usually but I set alarms off constantly on side streets especially narrow side streets.
I have the MPE + VRSF Catless DP + Eventuri Intake + VRSF Chargepipe (some other goodies soon); but this combo is easily one of the loudest exhausts I've heard and I get stopped and talked too all the time because of the sound. Idk what it is about that specific combo of mods but with the valves open and the car in Sport, Sport +, or traction (burble mode) it easily sets of any car alarm if I push on it. I don't ever purposely do it.......but uhhh it's an M2. I bought it over the M4 I had put my deposit on because I test drove it and it was just FUN. So I drive - Fun. That causes alarms to go off. Whoops. lol anyways yeah it's a loud exhaust even in stock form. I was pleasantly surprised by that. |

The problem is that it will likely irk my neighbors if I keep setting off car alarms in the garage we all share. It creates quite a din.
To the best of my knowledge, mine is the only car that has ever caused this issue for our building. Having said all that, I still think it's kind of funny. And cool. -scr |

If it were setting off all of the alarms I would say its an issue with how loud the M2 is but I don't think thats the issue. Some car alarms are set so sensitive that they are going off from simple proximity or mild vibrations so that is really their issue not yours. You have a stock car and are not doing anything wrong.

That's interesting, probably the low Frequency. I thought those shock sensors in cars were pretty much gone now, or they have made them less sensitive to noise. My Harley used to set off parked cars out side when I nailed it and rode by them. It does not do this anymore.

This would cause me to giggle every morning if that happened. I almost want to park next Cayennes now to test haha
Like you say, if I was the Cayenne owner I probably wouldn't be happy at having to leap out of shower to turn the alarm off every morning. Maybe they can do it through the app on their phone, I'd feel less bad in that case. |

a co-worker's truck has an aftermarket alarm what comes with a vibration sensor (i think that's what it is). she parks next to me and my m2 would set off her alarm nearly every time i start the car. i joke that her truck is scared of my little sports car.

With MPE, cold start nor valves closed driving has set off any car alarms so far - it's only been 3 days of ownership. I would say it's more on the car alarms that are sensitive.

Yeah, it happened once at work (underground parking spot)
Set off the alarm on a Volvo V70 parked 6-7 cars away from my spot. Was a bit embarrassing tbh However that is the onnly time and only car that it has set off the alarm for. My collegues cars parked right next to me, BMW 5-series and Audi Q5 are completely unaffected so I suppose some cars are more sensitive than others |
