Has anyone got ideas? My 2013 panamera turbo has done this several times. When I power off completely and restart, it goes away. No ODDB code.

Check engine
fault all wheel drive system
fault transmission
start stop mode deactivated
PSM failure

It then goes into a mode that is a bit rough engine running, and extremely delayed and slow shifting. Goes away when I shut down and restart.

Anyone???

replacing the coils fixed it. Thx everyone!

 

I had the same thing. The dealer replaced some engine coils. So far it hasn't come back.

 

Same thing here. 2 coils were failing.

 

Same for me
1 Coil

 

bad or weak battery will cause all kind s of weird stuff on many cars likes these...

 

Same here. 3 coils already #2#4 and #5.
I had OBD codes and I could identify them.

 

2010 4S with 41K miles. Just had the same issue this past weekend. My mechanic is starting with the coils and plugs. Waiting to see if this solves the issue.

 

replacing the coils did the fix. Thx

 

My 2012 P4S had those errors backin 2014 at 19,000 miles. Hoping it was the coils, but Porsche replaced the entire engine. I never got the full story from Porsche but they think scored cylinders were the ultimate cause.

Good to see yours was fixed easier than that.

 

Can you tell me the channels you went through with Porsche? I'm having the same issue on my 2019 P4S. I'm at 39k miles and my mechanic is telling me I need to replace the engine. I'm wondering if I should reach out to Porsche?

 

Exact same issue just happened with my 2010 4s. Coil 4 failed, replacing all 8 anyway.

 

YES. Good info for owners to keep in mind.

 

I just had this same thing happen to my 2013 GTS. OBD said it was cylinder #1. Mechanic swapped coils with #2, and the problem went way (so far). Conclusion was that there must have been a loose connection that was mitigated when they did the swap.
