I went forward with my E90 alarm install, and took some pics along the way. I would say that it is an easy install, as long as you have some mechanical confidence and experience. The "hardest" part is removing the left rear wheel to install the siren. Since our cars do not come with a...

This should work, almost $500 though:

How sensitive is the alarm? I mean how hard does the car have to be hit in order for the alarm to go off? Is there any way to make it more sensitive? Thanks!!

Anyone wanna try it first? Where do you plug this into? Can you also do software upgrades with this?

Thank for the great DIY! Easy to follow & installed it by myself (even I am a girl). However, there are some problems.......

After installed everything, the crown nose blink (Good!)
Test the motion sensor: Open the window, lock my car, throw in my bag from outside ==> the signal light is turn to panic mode, but siern didn't come out!!! (Working??? not sure)

When I brought my car to activiate.....
- They want to charge me $138 to activiate (in SoCal).... um... quite expensive though.... but finally agree to pay... left my car there.....
- Received a call later saying that I installed the alarm incorrectly and there is an error message when activiate my alarm... They need to un-install my alarm, program it first, then re-install my alarm.... (just plug & play for the installation, I don't understand how I installed it incorrectly, and the crown nose is working though... um...)
- They want to charge me $268 for un-installing, activiation and re-install again...
- Sorry, too much for me.... I just said "no"....

So I don't really know is my alarm working or not..... but at least my crown nose is blinking....

Any suggestion what should I do?

Thanks!

Where in socal? I was quoted $300.

Just installed the alarm into my E92. No problems with the install. The clown nose does blink after locking (fast for about 20 times, then once every 3 seconds thereafter). No chirp when locking/unlocking, no alarm when jacking the car up (tilt sensor), no alarm when opening the hood, and no alarm when hitting the panic buttons. Sticking my arm through the open window after locking the car DOES trip the alarm, so it looks like the interior motion sensor is functioning. Oh well, at least it'll go off if someone breaks INTO the car.

BTW I've got a July build with 30.2 software.

Working:
Interior motion sensor
Blinking clown nose (fast for about 20 times, then once every 3 seconds thereafter)

Not Working:
Unlock/Lock chirp
Panic button
Hood sensor
Tilt sensor

I did this install today. Piece of cake for the most part.

Like somebody here already mentioned, the hood switch wiring is no longer buried under plastic. The plug is very close to it's final resting place.

When I first got everything plugged in, I got nothing. No blinking clown nose. No siren anywhere. Then I realized that I didn't plug the overhead harness into the ultrasonic sensor but into the stock location instead.

No some of the stuff works.

I had my alarm installed last week..

I was going to install it myself but the actual activation/reprogramming would have cost 1 hr of labor @ 120 an hour.. I bought the alarm @ circlebmw for 235. (online price), when i asked how much will it cost to get it installed, they said for installation and activation they will charge me 1.5 hr.. = 180. so i figure i spend the extra 30 mins of labor for the installation, the total was 415. it was worth it bc they had to do a software update, i don't really want to mess with that..

now i'm going to install the DEI shock sensor.. ;-)

remove all parts and take it back to the dealer.. they should not charge you more than 1.5 hour of labor for all.. 180. dollars

Did anyone get the alarm programmed first, then install it?
The BMW PDF says something about updating the software first?

Also, did everyone disconnect the battery before the install? I though a few people did it without pulling the battery terminal?

Nope. install hardware first then do programming.


No

I did. Some have done without disconnecting it.

did any one tried on E92 coupe, which light dome the ultrasonic module fits? front or back

Back.

Rear. You can pull the light fixture off with your CLEAN fingers. Stick your fingers in the back and pull down. Comes off pretty easily.

I took my car in today to get the alarm activated. They told me that the software update for the alarm wouldn't go through. They couldn't get the car to chirp when locking or unlocking. They gonna work on it tomorrow. I see that some members are having or had similar problems. How did your dealer finally fix it?

Can it be that I didn't unplug the battery when installing the alarm?

How do you determine your software version and what are valid reasons to have the dealer perform an upgrade at no cost?

Not totally sure how to determine what version you have. I simply asked my dealer just prior to delivery. I have no way to confirm, so I'm just taking him at his word.

If anyone is interested, I'll do my best to walk you through this. You will need a valid hotmail account and a valid paypal account as this deal uses live.com to get cash back to your paypal account.

I followed the directions here http://www.fatwallet.com/forums/hot-deals/838081/ and followed the second post titled Quick Overview. I made my purchase through MorristownBMW. The link to their auction is here http://cgi.ebay.com/ebaymotors/BMW-A...QQcmdZViewItem They are a superseller with over 99% positive feedback.

After following the directions in the first link, I ended up with a 10% off coupon and then $70.50 back to my paypal account from live.com (thanks Microsoft). This seems to be a really good price and with the DIY instructions, hell yea.

Thanks to the tutorial OP!! Let me know if you have any questions about the purchase and I'll do my best to assist.

now thats a great deal

I've installed this on my e92, nothing seems to work. will take it to the dealership to get it activated and hopefully everything will work then..

Why are some cars having a tough time getting the alarm to activate? Dealer still has my car!
