More than ever, vehicles from different manufacturers build up on the same platform or engines from one manufacturer are used in vehicles from the other manufacturer. That’s why I can’t offer a topic at the same time in several sub-forums. That would lead to much more insights and lively exchange which would make sense for motor talk as well as for users. I noticed this at the M278 engine from Mercedes where it was located in the E-Class Forum, as well as In the CLS and S-Class forum, there are more posts on chain rattles. This info should be displayed in all relevant subforums where the engine is used. At the same time, all the information in the subforums should be bundled in a thread. This will allow errors to be detected faster and a wider mass of people will also learn about these problems.
