Hello, first of all I would like to tell you the symptoms: Open the door (central locking) with radio remote control and do not start the engine over 15 s: alarm system starts. Made my girlfriend quite at a loss. Interior light starts already when radio open. Pump for gearbox does not work when door open Summer for standing light. If I open the door and don’t get in, the vehicle locks the open door again, at least the lock. All this has worked recently, the summer is not so bad, because that is sometimes annoying. But the rest is not so practical. The pressure is now set up only when the ignition is switched on, so it takes a moment, but the Lupo 3l can then start normally. I changed the pressure storage last year. This entry allows me to conclude that the door contact switch in the door lock is installed:https://www.motor-talk.de/…/…-and-stand-abblendlicht-t53886.html I also did not have to buy the new door light with the radio.
