The steering adjustment feature of the CLK500 is non-functional.

[ForumGuru]

Greetings, esteemed individuals. I kindly request your assistance. The electrically controlled tilt and reach adjustable steering wheel of my just acquired CLK500 is now non-functional. Upon using the buttons responsible for steering movement, I perceive an audible clicking sound, although I do not detect any accompanying motor noises or observable motion. According to available literature, it has been suggested that applying force to the steering wheel while simultaneously activating the corresponding directional button may potentially alleviate any motor-related issues. I am inquiring as to if there exists an independent fuse for this particular component. However, it does not seem to be included on the fuse list. Additional suggestions would be much welcomed. Thank you.

It seems that you are encountering a similar issue to the one I previously had (which I have already resolved). The tilting mechanism ceased to function properly while attempting to make adjustments, producing a similar audible 'click' sound. However, the reach adjustment feature remained unaffected. Rather of forcefully striking the wheel, a method I found undesirable, I opted to apply pressure by leveraging my body weight while simultaneously using the downward adjustment lever. This action successfully disengaged the column/motor components.

If the clicking sound is audible, it is reasonable to infer that the issue is not with the motor power, but rather with the motor or gear being obstructed at its maximum position, similar to the situation I encountered (assuming that convenience entry/exit is enabled on your specific model).

Greetings, I appreciate the provided information. The lack of movement in both the tilt and reach mechanisms raises suspicions that the issue may not be solely due to being stuck. However, the presence of a clicking relay indicates the presence of power and maybe shows that the mechanism is really stuck. The absence of a motor spinning sound is indicative of the drive's functionality, suggesting that it is not damaged. I have attempted to use physical force and mass as potential solutions, although so far, my efforts have been unsuccessful. Perhaps the application of a spray lubricant to the gears might perhaps provide assistance in resolving the issue at hand. This aspect of the product proved to be somewhat bothersome, since it was the one feature that I neglected to evaluate before to making the purchase.
The convenience mode has been disabled.
Furthermore, it has been observed that the chairs in question had the ability to move, however they do not seem to possess the memory function. It remains uncertain if these two issues are interconnected.

The possible inference that may be drawn from the non-functioning reach adjustment is that there may be a cause other than jammed gears. Additionally, it is worth considering if you also perceive an audible click while attempting to engage the reach adjustment. One individual who provided assistance on my discussion thread proposed the notion that by removing certain trim components, it is possible to access the worm gear, which can then be greased. my is a task I intend to do in the future. Although my advise pertains specifically to a W205 C class vehicle, I think that the process would not change much for your particular automobile.

All directions exhibit an auditory click, but there is no corresponding physical displacement. I have attempted to use the steering wheel whacking method. However, the efforts were unsuccessful. I have scheduled an appointment for a Star scan in the near future, during which I shall ascertain if any pertinent findings are discovered. One potential positive aspect is that the absence of audible motor sounds suggests that there may not be any malfunction in the drive (presumedly). It is frustrating because I am unable to get the optimal position. It seems that the mechanism may be obstructed by the wheel when it reaches its highest point of movement. I appreciate the guidance provided.

I have received an estimated cost of around £500 from a renowned Mercedes expert for the installation of a functional, pre-owned steering column. Does it seem acceptable or too high?

[DreamWeaver]

The proposition seems to be rather satisfactory, since I have come across individuals who have cited quotations reaching high four-digit numbers from dealers.

It is informative to be aware of this. I want to see an auto electrician first to ensure the absence of any potential wiring, relay, or other related concerns. Subsequently, I will provide an update to potentially help others.

Subsequent communication from an automotive electrician: According to his statement, the malfunctioning of the motor position sensors necessitated the installation of a new column. Nevertheless, his manipulation of the device has inadvertently activated one of the motors, namely the telescopic motor responsible for inward and outward movement, resulting in partial restoration of functionality. Based on my observation, it seems that the motors have been inactive for an extended period, necessitating a little movement to reach a pristine area on the commutator. This proposition may be regarded as a hypothesis. My subsequent objective will include attempting to access the up/down tilt motor and adjusting its rotation slightly in order to realign it with a suitable portion of the commutator. Would anybody happen to possess knowledge of a reliable instructional resource for this task, or have personal experience in its execution?

I trust that this information will be beneficial to others. Thank you for your response.

Has anybody successfully resolved the issue of a malfunctioning electronic tilt adjustment for a steering wheel? It has been suggested that striking the wheel while using the buttons may resolve the issue, however I have not yet had success in my own attempts.

The proposed course of action involves gradually removing the wheel adjustment mechanism with the intention of accessing the motor. Subsequently, the motor would be manually rotated in an attempt to initiate its spinning motion, on the assumption that it has not suffered any damage. Any further recommendations or comments would be much appreciated.

I have chosen to adhere to the instructions outlined in this article in order to access the motors. As said before, one of the motors has successfully started operation, while the other remains non-functional. I intended to manipulate the connections, spin the motors in the event of uncertain bushings, and so forth. Currently, I own two malfunctioning electric steering motors.The term "wallbash" refers to a colloquial expression commonly used to describe a
I shall proceed to schedule an appointment with the doctor in order to get their professional opinion. The electric adjustment feature no longer holds appeal to me, since I find it to be somewhat inconvenient.

Have you examined the fuses?

[ForumGuru]

Yes, everything is satisfactory. One of the motors was functioning nonetheless, thereby excluding them from consideration.

[ForumGuru]

Currently, one of the two motors has resumed functioning (namely, the telescopic reach motor). This development is cause for celebration. This situation prompts me to hesitate prior to investing £500 on a used steering column. I am questioning if all steering columns of this kind possess such questionable reliability.

In the event that the electrically adjustable steering wheel of your w203 or w209 vehicle becomes immobile, it is recommended to first perform standard troubleshooting procedures such as checking for a malfunctioning motor or a broken dogbone, as well as resetting the motor limits. If these measures prove ineffective, an alternative method involves manually energizing the up/down and in/out motors by applying a ground and a 12-volt power source to the terminals labeled GREEN and BLACK, respectively. It is important to note that the terminals labeled red and brown are designated for the Hall sensor and should not be used for this purpose. The act of manually activating the motors independently of the control module's instructions is a common cause for their lack of movement. We anticipate that the provided information will be helpful in addressing the query.
