Paqngo Posted May 23 Share Posted May 23 We have encountered an unusual issue with our 2014 C220D Waggon equipped with the exceptional Airmatic system. After experiencing issues for many days, I decided to use a code reader to diagnose the problem. The number C152664 indicates a problem in the rear left sensor. There is a signal that is very unlikely to occur. Thus far, the situation has been quite uncomplicated. The sensor must be removed and replaced with a new one. Now the enjoyable part starts. As you are aware, there are two Torx screws securing the sensor. I find it unenjoyable to access and I am not enthusiastic about the act of unscrewing. Do not worry, remove the bracket and do the task on the workbench. There is just one clearly visible 10mm nut. I am unable to locate any further fasteners on the bracket. The object exhibits a noticeable lack of tension when the 10mm nut is removed, giving the impression that it is securely attached to another location. Do you have any suggestions on how to remove the bracket and sensor simultaneously, or is the only method to remove the sensor by unscrewing the 2 Torx screws? Thank you all in advance!

Paqngo Posted May 23 Author Share Posted May 23 By removing the 10mm nut from the bracket, it is possible to lift it upwards using a spike as a pivot point. This allows the end with the spike to travel towards the front of the vehicle, so freeing the bracket and sensor for further work on a bench. It seems like there is a sensor on every wheel, rather than just the front wheels, and there is just one sensor on the rear anti-roll bar. Let's see what Merc brings to us in the morning. The subsequent enjoyable phase will include the events that occur after the automobile has been installed and is started for the first time. Will the vehicle's suspension automatically adjust and become balanced, or will it need calibration? The maintenance of our previous Vario model is far more straightforward.The user's text consists of two emojis: 🤣 and 😂. Quote Link to comment Share on other sites More sharing options...

Mistral Posted May 23 Share Posted May 23 I believe it may need calibration. However, there is a possibility that you may have a fortunate outcome. I own a 2011 vehicle, and the only sensor installed in it is responsible for regulating the xenon levelling system. I have successfully loosened the nut, but I have not yet managed to detach the bracket. For my next endeavour, I plan to detach the arm in order to facilitate the removal of the bracket on the workbench. Quote Link to comment Share on other sites More sharing options...
Paqngo Posted May 23 Author Share Posted May 23 The storyline becomes more complex and intricate! The suspension only has sensors located at the wheels, with no sensors on the rear anti-roll bar. I purchased one from the authorised dealer who shown exceptional courtesy, however they did advise me to have a seat before disclosing the price. The price is somewhat over £200, however it is essential to have one. Well, I may as well tidy up the bracket and give it some attention by using Jenolite and applying a fresh coat of paint. Everything is ready and the vehicle from Mercedes arrives. Impeccable timing! Upon opening the package, one will find a fully assembled item, including a bracket, working rod, and a clip-on component for the top suspension arm. Let us get enthusiastic and assemble it! Now that is over, let's begin. The lack of mobility is somewhat bothersome. It is now time to follow Mr. Greedy's advise and adjust it accordingly... Once I get the necessary knowledge or information. Do you have any recommendations? Quote Link to comment Share on other sites More sharing options...
Mistral Posted May 23 Share Posted May 23 I feel that it is necessary to use an official version of STAR, either via an independent expert or a Mercedes-Benz dealer. Quote Link to comment Share on other sites More sharing options...
Paqngo Posted May 23 Author Share Posted May 23 Let's begin! I have three diagnostic kits available. One of them is outdated and can only communicate with Sentinel steam vehicles. I had a disagreement with the Launch one device, which is capable of doing various tasks. After resolving the error codes, I proceeded to start the calibration process. The comperror started but no further actions occurred. I performed this action 3-4 times before switching to our Foxwell device. I performed the calibration process three to four times, but there was no detectable movement. Considering the complete lack of enthusiasm and effort, one would have expected even a little display of curiosity. Unfortunately, the diagnostic kits I have do not provide suspension air pressure, which complicates matters. Is it possible to recharge the system using an external compressor? Is it necessary for it to be disengaged from the bumpstops before it begins to function? Do you have any suggestions or thoughts? Recommendations? Indeed, The automobile is first started and the vehicle's suspension is activated. However, after a few minutes, a warning message appears on the instrument panel in bold red font, indicating that the vehicle's height is too low.
