CheckoutThe blocker is responsible for unlocking the steering wheel, its purpose is to recognize the key in the ignition lock, unlock the steering wheel when it is installed, and lock it when removed. If the key is not identified, the steering wheel does not come out of the lock mode, the car does not start, then this means that not everything is in order with the lock and the ELV steering shaft lock needs to be replaced.
Replacement features
You should not start repairing yourself, amateurish disassembly leads to serious consequences:
the steering column fails;
the wiring closes;
deformation of adjacent parts occurs if the connection is incorrect.
Prevention of expensive replacement of the ELV steering lock - periodically carried out car diagnostics. If the steering latch does break, then it should be replaced in car services that have professional licensed equipment, tools, specialized software that accurately scans the error code that determines the nature of the defect.
How to determine the failure of the latch?
The most common blocker failure is in Mercedes with a W204, W207, W212 body, regardless of the year of manufacture. According to the statistics of calls to service centers of car owners who have encountered a problem, the blockers fail after 5 years of operation.
You can determine the breakdown by the following external signs:
when the key is turned in the ignition, the car will not start;
you can open and close the car using the key buttons;
the steering wheel is not unlocked or is constantly in the unlocked state, not responding to any actions;
dashboard does not turn on.
Solutions to the problem
There are several options for solving the problem with a failed steering shaft lock:
Replacing the ELV steering lock with an emulator. This option is reliable and has the advantage of an optimal price-performance ratio.
Replacing the blocker with the original one. When making such a decision, the car owner will face the problem of long-term and costly repairs. In dealerships where the original blocker is ordered, it will be necessary to purchase a service “orange” key in parallel to put it into operation. The key is not given to the car owner, and the car must be in the dealer service for the time of replacement. In time, such repairs take 3-4 weeks and cost about 50,000 rubles.
Replacing the ELV steering lock with the original, used one, equipped with a new motor.
Perform an express replacement of the blocker. The procedure is as follows: the master goes to the car parking place, dismantles the blocker, in the car service a new latch is programmed in accordance with your ignition key, and within 1-2 days the master arrives to install a new adapted blocker on the car. Warranty for the replacement of the blocker in car services is six months.
Irrational blocker repair
There is an option to repair the blocker. Some owners turn to a car service with a request to restore the original blocker. Restoring the latch is not always possible, and if it is repaired, then the resource of the part is very limited, since manufacturers do not produce spare parts for blockers, and the craftsmen put used spare parts. Given the short service life of a new device, a repaired one with used components installed will also not last long.
The blocker has software that fixes the number of errors. During the repair, it is impossible to say how many errors are left before the threshold value. Therefore, no one can guarantee that the steering wheel will not jam immediately after the repair of the blocker in case of unsuccessful parking.
Given the shortcomings of the repair, when the blocker fails, the best option is to replace it.
