I own a 2010 BMW Z4 and I'm experiencing some issues: the check engine light is on, there's jerking during acceleration, and the engine feels unsteady. Last year, I had similar problems and replaced the coil packs and plugs, which resolved the issue. However, after just 6,000 miles, the same problems have returned. My code reader indicates cylinder misfiring, suggesting that the coil packs and plugs need replacing again. Is it common for coil packs to fail so quickly, even when using top-of-the-line parts? I spent around $400 on recommended coil packs and plugs. Any insights or advice would be greatly appreciated. Thanks in advance!

It's unusual for high-quality coil packs and plugs to fail after just 6,000 miles. Before replacing them again, check for any oil or moisture in the spark plug wells, as this can cause misfires. Also, inspect the wiring and connectors for any damage or corrosion that might be affecting the coil packs. If everything looks fine, consider having the fuel injectors checked, as they could also cause similar symptoms. Let me know how it goes or if you have further questions!
