Macan's Metal Debris & Power Loss: Camshaft Crisis?

Hey there, I had very similar issues with my 2018 Porsche Cayenne last year. The symptoms you're describing sound exactly like what I experienced, rough idle, power loss, and that distinctive ticking from the valve area. In my case, it turned out to be a defective valve servomotor that was causing the camshaft timing to go haywire. Took it to the Porsche dealership in my area, and they diagnosed it pretty quickly. The metal debris in the oil was actually from the worn servomotor components. They had to replace the servomotor and do a complete oil system flush. It was definitely a serious issue that needed immediate attention to prevent further engine damage. The repair took about three days, but it was worth it. The engine's been running smooth as silk since then. Given the symptoms you're describing, I'd strongly recommend going to a certified Porsche dealership rather than a general mechanic. This isn't something you want to mess around with, especially with the metal debris situation. Hope this helps!

Thanks for sharing your experience! That's really helpful since it sounds exactly like my issue. Curious, do you remember the total cost for the servomotor replacement and system flush? Also, has everything been running smoothly since the repair, or have you noticed any other quirks pop up? My Macan's been my dream car, so I want to make sure I get this fixed right the first time.

Hey again! Happy to give you an update! Since my earlier post, I actually went ahead and got my Cayenne fixed at the Porsche dealership I mentioned. The final bill came to 405€ for the valve servomotor replacement, which honestly wasn't as bad as I was expecting for a Porsche repair. The best news is that it completely solved the camshaft adjustment error I was having. My car's been running absolutely fantastic since then, no more weird ticking noises, power's back to normal, and the engine's purring like a kitten. It's been about six months now, and I haven't had a single issue pop up. Trust me, going to the Porsche dealership was definitely the right call. They knew exactly what they were doing, and the quality of work was top-notch. If you're still worried about your Macan, I'd say just bite the bullet and get it done. Your dream car deserves proper care, and this isn't something you want to leave to chance with a general mechanic. Let me know how it goes when you get it sorted!

Just wanted to update everyone! I took your advice and went to the Porsche dealership. what a difference compared to my old mechanic! You were spot on, it was indeed the valve servomotor causing all the trouble. They did a thorough job diagnosing everything, replaced the faulty parts, and did the oil system flush. Bill came to around 450€, which honestly wasn't as scary as I'd imagined. The best part? My Macan's running like new again! No more ticking, full power restored, and that worrying metal debris issue is resolved. Had to wait a couple of days for the parts to arrive, but the dealership kept me updated throughout the process. They even gave me a detailed report of what they found and fixed. Really appreciated their professionalism. Thanks again for the recommendation! Sometimes paying a bit more for proper expertise is totally worth it. Just relieved to have my dream car back in perfect shape!
