2019 Base Cayenne engine control fault @ cold start
Hi everyone,
Did anyone get this warning before "Engine control fault, driving permitted, visit workshop" during a cold start? it happened more than once, sometimes in conjunction with " start stop failure". I went to the dealer and they changed 1 spark plug that they claimed was causing a misfire. However, it happened again 2 days later. The problem disappears after turning off/on engine.
I noticed that this started happening after my 25,000 KM service at the dealer, they didn't do anything during this service except changing the oil. Any ideas?
Thank you

My 2019 base Cayenne had a stop/start failure warning but not your other issue. So chances are the two faults are not connected.
BTW, I became hopeful when I saw the stop/start error message that the AS/S functionality had died and I would no longer have to switch to Individual or Sport Mode whenever I started the car. But, alas, the error message disappeared the next time I started it and the error has not reappeared. Damn!

I got the same misfire error today after about 3000+ miles on my 2022 Cayenne E-Hybrid. It was error code PO300, PO304, PO306. I got the chatter on my dashboard about "Engine control fault, driving permitted, visit workshop". I pulled into a starbucks and when I can back out all lights were gone. The only thing I can think happened is that I started it up in E-Mode in the morning and was merging onto a highway going about 70- 80 MPH in E-mode, to stay up with traffic. i could see the RPM move up so that told me I was out of E-Mode and in ICE mode. Shortly aftwards all of the lights starting going off. The good thing is I took a picture of the error just in case it keeps happening and I need to present it to the the dealer or porsche.
