Common Issues with the BMW M3 Engine?

I've been experiencing some performance issues with my BMW M3 lately. Are there any common issues with the M3 engine that I should be aware of?

Hi John, there are a few common issues with the BMW M3 engine that you should keep an eye on. One common issue is with the VANOS system, which controls the variable valve timing. Some owners have reported issues with this system, resulting in poor engine performance. It's important to properly maintain and service the VANOS system to avoid any problems.

Another common issue with the M3 engine is with the rod bearings. These bearings can wear out over time, leading to engine failure if not addressed. It's important to regularly check the condition of the rod bearings and replace them if needed.
