Remote alarm issue on Z4 Roadster S
Remote alarm issue on Z4 Roadster S
When using the remote fob to lock the car, the alarm siren can tend to go off at varying intervals. However when I lock the car with the key I don't have an issue.
I've checked & tested the bonnet sensor as I understand that can be a cause. But the alarm still goes off. I've been told it could be the tilt sensor. If so is this an easy fix or can it be turned off via a management diagnostics system?
Any advice would be appreciated?

I'm not 100% sure, but I believe that locking the car with the key does not engage the alarm.johntyper wrote:When using the remote fob to lock the car, the alarm siren can tend to go off at varying intervals. However when I lock the car with the key I don't have an issue.

Locking with the key disables the alarm and immobiliser but you may not want to do this all the time due to the increased risk of theft
You can easily check if it's the tilt/motion sensors by double clicking the 'lock' button on the key, this will will disable the tilt/motion sensors but leave the alarm/immobiliser armed.

Had a similar issue on my Z coupe. It also comes with the same alarm. had it checked by bmw couple of times and then it just stopped going off! couple of common issues I was told:
Bonnet switch for alarm can corrode (so some wd40 , acf 50 or any electrical contact spray will help - Im sure you know already a man of your calibre but its behind the engine in the centre towards to windscreen wipers! )
Having coins in the little cubby in front of the gear lever!! this can interfere with the microwave sensor for the alarm....apparently.
Hope this helps!
