Macan's Timing Chain Nightmare: Metal in Oil Alert

I had similar symptoms with my 2020 Porsche Cayenne last year. The unusual shutoffs and power loss turned out to be a faulty crankshaft position sensor, not the timing chain. The metal in your oil is concerning though, that's different from what I experienced. When my sensor went bad, the car would stall at stops and struggle to maintain idle. Got it diagnosed at the dealer since these engines are pretty complex. They found the sensor was giving incorrect timing signals to the ECU, causing the engine to run rough and shut off. It's definitely a serious issue that needs immediate attention, you don't want to risk damaging the engine. While my fix was relatively straightforward with the sensor replacement, your metal in oil situation suggests you might be dealing with something more severe. I'd strongly recommend getting it to a Porsche dealership or certified Porsche specialist rather than a general mechanic.

Thanks for sharing your experience with the crankshaft sensor issue. My Macan's at the dealership now and they're thinking it might be similar to what you had. Curious, do you remember roughly how much you ended up paying for the sensor replacement? Also, has everything been running smoothly since the fix? I'm hoping it'll be just the sensor, but that metal in the oil's got me worried about bigger problems.

Hey there! Thanks for asking about the costs. Yeah, after taking my Cayenne to get checked out, it turned out to be exactly what they suspected, the crankshaft sensor was definitely shot, and they also found the position of the crankshaft to camshaft was off. Got both issues sorted out and it came to 250€ for the sensor replacement. I can tell you're worried about those metal bits in your oil, totally get that! But I can say that since getting mine fixed last year, my Cayenne's been running like a dream. No more unusual shutoffs or power issues at all. It's like night and day, honestly. The engine's smooth as butter now. Hope your Macan's issue turns out to be as straightforward as mine was. These Porsches can be tricky, but once you get them sorted with the right fix, they're amazing machines. Let me know how it goes at the dealership!

Just got back from the dealership today, and I wanted to update you all on what happened. Turns out it wasn't as bad as I initially feared! The sensor replacement was pretty similar to what you paid, came to about €275 with labor. They also did a thorough oil analysis, and thankfully, those metal bits weren't as serious as I thought. Just some normal wear and tear that looked worse than it was. The whole experience wasn't nearly as painful as my last mechanic visit. The dealership team was super professional and walked me through everything they found. Been driving it for a few hours now, and wow, what a difference! No more unusual shutoffs or weird noises. The engine's purring like it should. Thanks again for sharing your experience, it really helped calm my nerves when I was freaking out about potential timing chain issues. Lesson learned: sometimes it's worth paying a bit more to get it done right at the dealership, especially with these high-performance cars. Really appreciate all the advice!
