    Hi all,

    A new problem developed; went for a drive today with my son, and upon leaving and locking the car, I almost closed the door, but she beeped 4 times quickly about 20 seconds after lock.
    I don't want it to beep there at storage location, so I went back to unlock it. It unlocked fine, no extra beeps. Lock it, and there are 4 beeps again after a while (20 seconds or so).

    Checked all doors, engine , boot to be closed. Still beep. I felt nervous leaving it there like that so I disconnected the battery and left it like that until next time.

    I cannot find anything in the manual regarding this, it must be signaling some code beeping 4 times exactly... anyone knows what it is?

    Many thanks for any feedback.

    It's an error code. Two beeps is a problem with one of the closures, and four is something else (I forget).

    And of course Happy Thanksgiving all!

    PS> I checked online, and read all my manuals to find anything, there is nothing in the immobilizer/alarm chapter about the error codes..

    My 355 beeps 4 times on lock when something is open. In my case it’s the frunk for the battery tender. Double check all doors and hoods and perhaps a sensor is failed on one?

    I get the occasional 4 beeps on my 360. I've ignored it; no common denominator. Has not been a problem.

    Interesting. There is no mention of 4 beeps in the manual.

    Note that the F430 alarm/immobiliser system is a little different from 360/355 systems. There are two separate ECUs:

    Alarm ECU (under the pedals)
    Immobiliser ECU (under the dash near the steering column)

    There is no mention of 4 beeps, only 4 flashes of the LED. Are you getting 4 flashes prior to turning on the ignition?

    For info: Looking at the wiring diagrams, the alarm ECU cannot differentiate between an open engine compartment and an open luggage compartment (so the 4 flashes may indicate either). The switch wiring is basically spliced together. Note, however, that because the instrument display wiring (for open engine compartment and open luggage compartment) is in parallel with the alarm system, diodes must be used to allow independent instrument warnings for frunk and engine lid.

    Turning off the battery is no guarantee that the siren will not go off (at least not on my F355)

    Thank you again ! I will look at the led for sure next time when I get to it. I don't see the led to be honest flashing at all, only after I lock it, it flashed about once a second or so, but I did not look at it after locking...
    It definitely beeps 4 times, after 20 seconds or so after locking. I know the alarm could go off with battery off, but I unlocked the car by the button, disconnected battery and locked it again just by the key, so nobody could get in just in case... not that it would help much if they broke into the garage...

    It might be offending door which is not dropping the window as well, maybe the door close sensor is busted now ? Not sure, more digging is needed..

    Cheers

    Interesting. I forgot you had a window drop problem. I don't have a wiring diagram for the standard F430, but on the Scud, the Alarm ECU receives at least two different "open/opening" signals from the doors:

    1) an earth from the switches on the driver's and passenger's door frames (near the hinges).
    2) an earth from microswitch "M004-B" inside the driver's door latch via diode "P201". That same doorlatch switch sends an earth to the following:

    Interior light time delay module pin 7 via diode "P201"
    Driver's door open warning light (instrument binnacle)
    Window ECU (possibly one of the inputs for window drop)
    F1 TCU

    Using the car without the window dropping? The winnow must be binding on the A pillar?

    If you move the window up or down, it drops when you get out of the car. It then stops dropping further... It has actually enough play to open relatively easy... I am not driving anymore it until spring, so I'll get to it then ... need to open the door fully to check for continuity in the plug, I suspect a faulty switch or sensor.

    I was so stupid, I was wondering why you have to smack the door so hard to close it; it was because of the window dragging on the rubber seal up the top :)

    Be careful with that - it'll bend the window lift assembly and create a lot of free play.
