Mercedes steering lock repair (W204, W207, W212) is a budget solution to the problem of restoring its functionality (compared to the cost of replacing it). Therefore, many car owners come to a car service with a request to restore the blocker. Since manufacturers do not produce spare parts for bollards, worn parts are replaced with functional used components. Therefore, the service life of the repaired blocker is not long, given that the new one works without breakdowns for no more than 5 years due to its design features. This fact can be attributed to the minuses of the repair.
The second disadvantage is that it is difficult to determine the state of the part at the moment by the blocker software error counter, therefore it is not known how long the latch limit will be exhausted and how long it will last after repair. The warranty for the blocker that has undergone repair is not large.
The advantage of the repair is its low cost, and the guarantee of the work done is the decency and technical literacy of the car service masters to whom you turn for help.
