Moin, after 4 years old MB Abstinence, a W251 R 500 Bj.01.2007 found the way to my yard. What I didn’t notice yesterday when I bought is that the driver’s door is not locked. If I press down the pin when the driver’s door is closed then I have to lock the car several times and unlock it bits I can open the door again. However, the pin remains below when I open the door from the outside. Only who I use the inner door handle the pin goes up again . I’ve already unscrewed the pin and let some ballistol run down on the drawbar. Can it be that the lock itself is anything like heavy from the inside? Greetings Rudi
