Mercedes vehicles are highly complex machines equipped with numerous sensors that continuously monitor the various systems within the vehicle. These sensors constantly report their data to the Engine Control Units (ECUs) for each system, providing ongoing performance feedback.

 

If a fault occurs, an indicator light on the instrument panel may or may not signal a problem. However, a fault code will definitely be recorded in the ECU. To efficiently read these fault codes, as well as data from other Mercedes ECUs, the correct tool is required.

 

Using my diagnostic tool It performs a thorough analysis of the car’s entire electronic system and receives regular updates on any new technical information. After completing the analysis, I can process the data and conduct various tests to accurately identify the source of the fault.

"Enjoyed listening to his explanations of my faults on the car - very intelligent and interesting man."

​

The results I obtain are time-stamped and dated. If requested I can send a copy of my findings for your personal reference.

 

Customer complaints about their vehicles may not always trigger a fault code; it is not simply a matter of connecting a computer and having it identify the issue, as some may believe. However, when a complaint

pertains to a specific area of your Mercedes, it is crucial to have specialised knowledge of the brand to conduct further testing effectively. With the customer's authorisation, I can then accurately diagnose and address the fault.

"Very conscientious approach, Paul even waived his fee for some work he did over and above his quoted price."



If I have the necessary part with me, a second appointment is usually not required. However, if the part needs to be ordered or collected, another appointment may be necessary.

 

When working on your vehicle, I do not rely on guesswork. I prefer to be certain of the issue, particularly given the cost of parts and the 'no returns' policy on electrical items. It’s crucial for me to avoid guessing as it impacts my reputation directly.

 

Some mechanics may guess repeatedly and eventually resolve the problem, but this approach often means you, the customer, end up paying for their trial-and-error method. In some cases, you might even be left with the same issue unresolved.
