from the afflicted friend : When i bought my car, the red alarm system LED blinked, what means the car was forced by a burgler. Cause there where nothing else, i drive, drive, drive ... After some weeks, the blinkin LED was off, so what – one problem more dissolved by itself. 2-3 weeks ago, the red LED cames back, blinkin more alerting then ever. Same days my horn tuuts just because – whenever it wants. So i unpluged the fuse of the horn and it was quiet. On a bad day, the battery of the 440 was totally down, think my little daughter turned on the interior lighting. After my best friend supports me with givin assist-starting, we turned on the Radio, switched on the blower and drove for buying some DIY stuff in a lokal DIY store. After ca 15min, the engine runed about 5min in idle, the machine spluttered and finaly stoped. We are lucky Guys, so we stand on a parking area when this happens. Now we tryed to turn on the motor several times, until the battery again was down. The whole time i thougt it must be the alarmsystem ... the LED, the horn, witch is also part of the alarm. We looked, like sheeps in a clock-work, under the hood and don´t found no bug. Later we´ve got my friends vehicle to mine and tryed with his auto battery again and again to start this f**k´n car. The very last time i tryed, the motor starts and as fast as able i brang it home. Days later i checked all fuses, all ignition cables, all relays, just looking for visible damages on a component, i dryed to read out the error-memory , findin nothing. Halfhearted i smashed all back in the car and gave up. Next day i startet the motor and ...? I drive, drive, drive ....! Don´t know what realy happend, maybe the battery took too much current from generator (radio and fanomatic „ON“), so the electr. controller and/or the ignition got´s too less respective too inconstant power suply, maybe i jiggled the right contact, maybe the siliconespray on the idle-actuator was the solution of the prob.
