Seat Alhambra 2002 1.9 PD AUY
Hi,I wanted to make my car to signal by horn, when I open it or close it.I have followed these instructions node/253329, it said I have to get the signal from comfort electric P2/pin1,I checked it but there is no signal! Anyone knows what to do??? My controler is:7M3 962 258AC
Do I have to program something to make it work???
THANK YOU
Hello Guest,
if you do not have an original anti theft device in the car the horn for the signal is not present.
But you can attach the horn to a contact on the MFE. I can look up the contacts if you want to…
Hi, Uwe, I will try your version,let see if it works.
I tried,recode:04096 adaptation CH10 Germany,not working,there is no 12V on pin1 when I close or open.
There is one fault code:01134 Alarm Horn(H12) No Comunication
The alarm horn is checked by its impedance. It propably does not apply the voltage if the impedance is wrong.
And even if the MFE sends the signal to the horn: The pulse is quite short and can not be seen with a multimeter. Try using an LED with a resistor (or even better a horn 
)
You must connect a horn on plug P2 Pin1(MFE) and the other Pin on earth. The 12V-signal is only 33,4ms long.

I will try,Thank you
I will report what happend:)
I checked with a led still nothing!
Probably because the impedance of the LED + resistor is much higher than the impedance of the horn.
So the signal is not activated.
Hi!
A friend of mine solved the mistery ,he programed with eeprom the komfort window and also the horn for opening/closing,now the signal is there (P2.pin1):)))))
For the komfort window:
login:21318
ram reading:original value was 17,
eeprom write:17+2=19:)
For the horn I dont know,but someone needs I can ask him
And I figured out for the ausstellfenster retrofit by komfort!!!but I cannot paste on this page
Its really simple you only need one relay
Gruß Uwe
