MERCEDES A B R Class W169 W245 W251 door lock actuator repair kit 2 springs kit
SYMPTOMS OF FAULT
Door lock jumping up and down quickly, door not locking or only periodically, door lock rattles.
THE FAULT
A spring within the door lock actuator mechanism snaps causing the locking faults.
It is a common fault on these vehicles for a small spring within the door lock actuator to snap causing the symptoms noted. The original spring within the mechanism is very thinly wound and is constructed from a poor quality steel which will inevitably corrode and the spring will snap.
Previously this necessitated the complete replacement of the door lock actuator unit at vast expense, the vehicle manufacturer has not altered the spring design / construction over the years so even installing a complete new actuator would only be a temporary solution.
THE SOLUTION
Our replacement improved design / material springs allow you to repair the actuator.
Made from high quality Stainless Steel (will not deteriorate over time like springs offered by some others) our improved design thicker wound springs will restore your lock and will not deteriorate over time like the OEM part does, save the cost of a replacement actuator that will just fail again. Produced to the finest tolerances for the perfect fit, thicker wound and reshaped to provide a permanent solution to the locking faults noted above.
