Mercedes-Benz cars are complex, and you are wasting time and money without an excellent diagnostic scanner.

The following video shows what the YOUCANIC full system scanner can do on a Mercedes-Benz. It is a great video to watch, but if you want to see the diagnostic process jump to the 15th minute.

YOUCANIC full system scanner also offers bidirectional support. What does that mean? If your car has an air suspension, you can raise the car with the scanner even if the engine does not start. The shifter on the steering column is defective? Well, you can use the scanner to at least shift the transmission to Neutral or Drive. You get the idea. Bidirectional support is usually a function that only comes with expensive scanners such as Star Xentry Diagnostics.

The best thing about YOUCANIC’s full system scanner is that it is not limited to Mercedes-Benz cars only. It has these advanced functionalities for all makes, including Audi, BMW, Honda, Acura, GM, and Hyundai, well, almost all makes and models. The software is already included; you don’t need to pay anything extra.

The Star Diagnostic Scanner (Xentry) is what Mercedes-Benz dealers use and the gold standard for Mercedes-Benz cars; the YOUCANIC full system scanner is undoubtedly one of the best diagnostic scanners for Mercedes-Benz vehicles. YOUCANIC full system scanner is better than iCarsoft MB II and most Launch scanners. YOUCANIC full system scanner can diagnose any control unit. View live sensor data from any sensors, not just engine sensors. Offers bidirectional support. Plus, it works on all other makes and is not limited to Mercedes-Benz cars. Best of all, unlike professional-level scanners such as SnapOn or ThinkDiag, it does not require a yearly subscription. Oh, and YOUCANIC has published many how-to videos teaching you how to be a mechanic.

Lastly, the YOUCANIC scanner works on 1996 and newer Mercedes-Benz vehicles. If you have an older vehicle, such as W210 or W208, that needs the 38-pin connector, this scanner will work but you need to get the YOUCANIC 38 pin MB Multiplexer so that you can access all vehicle systems. Check out an example report here.

2. TopDon ArtiDiag100




Today, we tested the TopDon ArtiDiag100 on one of the most sophisticated and complex vehicles, the Mercedes-Benz S-Class.

We could access every single module on the vehicle and read and clear codes where codes existed. Keep in mind that you will only be able to clear codes that are on STORED statutes. If a code shows the CURRENT status, you need to address the problem, fix the issue, and then come back to erase the code. When you reconnect the scanner, the code will show as STORED; you can clear the code at this point.

The ArtiDiag 100 will allow you to read and clear codes from any module, including Airbag, SRS, Transmission, Air Suspension, SAM, Central Gateway, Engine, etc.

Another advantage of ArtiDiag 100 over scanners such as iCarsoft MB II and Star Diagnostic is that it works on all vehicles, including Ford, Honda, Audi, BMW, Porsche, Subaru, etc.
