Cayenne's Ghost Alert: Tire Sensors Playing Tricks?

Hey! I can relate as I had a similar issue with my 2019 Porsche Macan (I'd say I have some experience with Porsches). The same thing happened, constant tire pressure warnings despite normal tire pressure. Took it to my trusted workshop and turned out one of the TPMS sensor batteries was dead. Cost me about 280€ to replace it, and that fixed the problem completely. Pretty straightforward job, took about an hour. Which engine variant do you have in your Cayenne? That might help me share more specific info about potential sensor locations and compatibility. Also, is the warning constant or does it come and go?

Appreciate the reply! I've got the gasoline model with 119767 KM on the clock since my last service a few weeks ago. The warning is pretty unusual, sometimes it stays on for days, other times it flashes on and off during a single trip. Good to know about your Macan experience! €280 doesn't sound too bad if it solves the issue. Did you notice any pattern with temperature changes when your warning would come on? Just trying to rule out if it's actually a pressure thing or definitely the sensor before I head in.

Hey again! Yeah, with my Macan (also gas model), I did notice something interesting about the temperature patterns. During my sensor issue, the warnings were super unusual like yours, didn't matter if it was hot or cold outside. That's actually one of the things that made me pretty sure it was a sensor problem and not actual tire pressure. You know what's funny? Before I got it fixed, I was obsessively checking tire pressures like every other day (what a pain!), and they were always spot on. Your symptoms sound exactly like what I went through, especially that unusual on/off warning during trips. That's a classic sign of a dying sensor battery. Since your Cayenne was just serviced a few weeks ago, did they mention anything about the TPMS sensors? Sometimes they can catch these things during routine checks, but honestly, sensor batteries can fail pretty suddenly. If you're getting those sporadic warnings like I did, I'd bet good money it's the same issue I had. Worth getting it checked out before you drive yourself crazy checking tire pressures!

Thanks so much for the detailed response! That's super helpful to know about the temperature independence, definitely matches what I'm experiencing. You're right about the obsessive tire checking too. I've been out there with my pressure gauge almost every morning like a nervous parent! No, the service team didn't mention anything about the TPMS sensors specifically, but I'll definitely bring it up when I take it in. Think I'll stop by the workshop next week, you've convinced me it's probably the same sensor battery issue you had. Really appreciate you sharing your experience, saved me a lot of worry about potential bigger problems. I'll update you on what they find if you're interested!
