Greetings to all..
Unfortunately I just had some issue with my 2017 991.2 carrera S.Im super frustrated because I had a service done at a porsche dealer just 1 week ago...
After the service I didnt drive my car and the next day I put it on a truck and send it to another EU country (I'll be there because of job and vacations for like 2-3 months)
RIGHT AFTER I got it delivered and after I started the engine , I drove for about 3-4 kms , and I did a soft kick down and that's when all my problems started.......

the car had Check engine light failure , ACC/PAS message , and PSM issue ! All those 3 together.
furthermore the car reacted very unstable, lacked power , was trembling like some engine cylinder wasn't working properly or something like that and also the auto start/stop system got disabled (had a message as well)

I managed to get it to my garage and I parked it there.
tried to turn of and re-ignite 2-3 times just to test it.
The first 2 times I didnt got any messages but again after a soft kickdown I had the 3 error messages when I tried to drive the car.
the third time I got a check engine light without even driving it...

The service which was done was the basic one (filters oil etc) plus they changed 1 coil spark.
this is so frustrating and I really dont get it.
My car has 36k kms and was running damn smooth smooth the service.
here are some pics (sorry they are in german)



Any idea? Anybody had the same issue? Wtf...!!
Thank you and sorry for the big message.

 

It must be service related. I would take it to a Porsche dealer right away. Probably it is something loose or not properly assembled by the Porsche tech who worked on your car. Hope it is simple and you get is sorted soon.

 

Damn... that's so frustrating I mean what the hell ? Dont they check when they screw things up???

 

Bump

 

I don’t read German, but when you say “after a soft kick down”, the problem may be PDK related.
Others have posted here about strange error messages that eventually pointed to a PDK failure.
I hope I am wrong......keep us posted on what you learn, and good luck.

 

My guess is something to do with the coil pack work.

 

Agree, coil pack is also a real suspect, but still wonder about "soft kick down"

 

When u mean soft kickdown I mean I didnt kickdown to make a 0-100 run, I just kickdown to like 110-120 kph speed to enter to the motorway.
English is not my native language so maybe I didnt explain it correctly
I'm thinking as well it has something to do with the coil spark and the change of it.
hope it's just that...

 

Coil pack problem. It's amazing how one bad coil pack can effect different systems. I would have that checked first. Especially the one they worked on.

 

Just to be clear, when you say kickdown, does that mean you downshifted a gear, say from 4th to 3rd, either manually, or automatic?
It seems that if it is really a coil pack issue (we hope), then transmission downshift should not be an issue?

Good luck, let us know the outcome.

 

When I say kickdown I mean I was at 0 speed then I pushed the gas pedal full down to speed up so as to enter the motorway.
or when I cruise for example with 50kph then I push the gas pedal and it gives more speed.
pdk works just fine, no problem with gear changes or any message about pdk.

Can you read the DTC in the ECU?
What's the mileage of the car?
