When Mercedes-Benz introduced the 722.6 5-speed transmission, they said it was sealed for life and required no maintenance. Then reality hit, and we learned the lesson quickly. Not only that it is an intelligent decision to service the transmission at 60,000 miles, but this transmission can leak oil, especially at the 13-pin connector. You need a transmission dipstick to check the transmission fluid level. Low transmission fluid levels can cause problems, including being stuck in gear or limp mode. If you have the Mercedes-Benz Transmission Dipstick Repair Tool, you can quickly check the transmission fluid level.

Instead of using a hexagonal bolt head, Mercedes-Benz uses a female Torx star head for optimum torque transfer. Whether they used them because the E-Torx bolt heads look sophisticated or to deter you from fixing your car, we don’t know. 🙂 You will find that many bolts on your Mercedes-Benz will require you to use  Female E Torx Star Socket Set.

Why You Must Have a Good Diagnostic Scanner

Mercedes-Benz cars are now equipped with at least 20 control units. Some flagship models, such as the S-Class, can have up to 50 control units. If one sensor fails, you could have Christmas lights on your instrument clusters, including several Visit Workshop warnings. As scary as these problems seem, they are very easy to diagnose. Just one sensor could impact multiple control units, so you get several warnings. Ultimately, they all may point to a single defective ABS wheel sensor. Instead of going into panic mode, get an OBD II scanner next time, plug it under the dash, and follow the on-screen promptings. Within minutes you will usually know what is causing those warnings. The best scanner you can use is the Mercedes Benz Star Das C3 or C4. While it is the most advanced scanner for Mercedes-Benz used by the dealer, it also is pricey and has a learning curve. The easier-to-use and affordable scanner we recommend to anyone, even if you have never used an OBD II scanner before, is the YOUCANIC full system scanner. 

YOUCANIC full system diagnostic scanner is a powerful tool that can help you troubleshoot Mercedes-Benz problems quickly and efficiently. This scanner can communicate with all the control units in your Mercedes-Benz, including the engine, transmission, ABS, SRS, and more.

Whether you’re experiencing issues with your engine, transmission, or other systems in your Mercedes-Benz, the YOUCANIC diagnostic scanner can provide valuable insight into what’s going on under the hood. This scanner can help you identify error codes, read live data, and perform special functions like reset adaptations or component tests. With this information, you can make informed decisions about repairs, maintenance, and upgrades to keep your Mercedes-Benz running smoothly.

Overall, the YOUCANIC full system diagnostic scanner is invaluable for any Mercedes-Benz owner or technician looking to troubleshoot problems quickly and accurately.
