What is a Mercedes door lock spring kit and why do the original ones fail?
The Mercedes models MERCEDES A B R CLASS W169 W245 W251 have a poorly designed spring in the door lock. Over time these begin to crack and get weak causing troubles with the door lock.
Issues range from the door lock bouncing up and down rapidly or even unwillingness to lock properly.
Here at I6 we have created a simple yet cost affective solution that will allow you to repair your own door lock actuator simply. our kit uses uprated door lock springs that will ensure the car doesn't face this issue ever again. We have listed the effected part numbers below.

Is it really that straightforward to install?
It really is! We provide the instructions and the tool that will make it alot easier for you to install. An extra small screwdriver will come in useful and it will take about 20 minutes to install.
The keyless Go door lock also uses the same spring mechanism and thus can also be repaired for this kit.
We recommend you purchase a set of 4 springs and overhaul all your door lock actuators. Chances are if one has failed, then the others aren't that far away from failing!
