Hi has anybody gotten the "Reduced Engine Power, Driving permitted, Visit workshop" notification on their TTS? I have a 2022 992.1 TTS which I bought 6 months ago with 1700mi, now at 5500. This has happened 3-4 times when I try to accelerate hard, rarely, not always. It goes away immediately after I restart the car. Also when the error does come up I haven't really noticed any reduced engine power.

Now the other issue is I had the error once before I tuned the car with M engineering and added Akrapovich exhaust/pipes. It has happened a couple of times again since. Now the car is under warranty but concerned dealer might try to deny because of the tune. Does this even need to be taken in for further diagnosis/fix? And if so will the dealer try to deny warranty with the tune?

Oh when it does happen it also gives this error with it " Porsche InnoDrive not available. Driving permitted, Service necessary". Again both errors go away immediately after restart and rarely come back when I accelerate hard. Thank you for advice.

Remove the tune and put it to stock. Drive it around stock till you get the error, take a picture of it immediately and bring the car to the dealer.

You likely have fuel injector issues would be my guess. The tuning will make this issue worse or pop up more often.

I agree with the previous post.

Have you checked for codes? This would be my number one task.

Thank you for your advice. Now my dealer is tune friendly, in-fact I got tune through their motorsport subsidiary. Do you think i should just take it in now or remove tune and retrigger error as you suggested?
The reason is the tune removal will be a pain in the *** cause the motorsport shop owns the tune license so gonna have to take it to them to remove/re add.

I would personally remove it.

Once the dealer hooks the car up to PIWIS, there is no control over what is sent to Porsche in Germany, the car could be instantly flagged and your warranty denied.

For that reason, I wouldn't take the risk myself, but up to you.

Alway remove tunes before a dealer visit, its easy enough. Good to have a simple code reader to download the codes and have a clue what your dealing with, also to keep the stealership honest. This happened to my buddy last summer, I downloaded the codes and it was injectors.
