Passenger door lock jumps up and down like a yo-yo???

[James Curd]

Hello,

Probably been asked this loads and loads but I cannot find the thread, I have an E320 CDI 03 plate and basically when I lock/unlock the car the passenger lock goes mad...de de de da, up down up down then locks? What part do I need to change?

Thank you

its a little spring inside but you need to buy a whole new unit.

No they arent easy to fit really.. very fiddly... im sure its been documented on here, just do a search..
