Hello, recently acquired an 87 Golf that was stored for 20 years. Really clean in and out. Automatic transmission. Installed a new battery and then opened the drivers door to get in and when I opened the door, the engine began cranking. Continued til I pulled the battery cable. Car will turnover with key out of ignition and ignition in off position if you open driver or passenger door. I then replaced the ignition switch. Sadly, problem continues. Please respond if you have seen this before! Many thx
Wow, that’s an odd one!
All I can think is some kind of short with the ignition system that is making a circuit when the door switches for the interior light is earthed.
If it’s been stored for that amount of time I would be checking to see if it hasn’t been a home for mice. They could have made a mess of the wire loom.
Dodgy immobilser / Alarm?
Usually linked into the interior light somehow to activate things by detecting the voltage drop when a door's opened... working in reverse and supplying, not disabling starter?
