Drove car a few weeks ago no issues. Parked it. Went to leave today and car is freaking out. Fuses looked OK. Headed to dealer. 2017 991.2 C2s. 15k miles.

Yikes. Hope your car is ok and it’s some weird computer glitch.

Was the car left on float charge? Low battery voltage can cause a bunch of wacky messages.

dflowerz

It was on a Porsche charger. I will check the battery voltage. Thanks.

dflowerz

Batt was 12.3 volts. Am putting it on the charger tonight just in case something happened with last charge.

Battery...?

dflowerz

Yeah, pretty sure I have a sulphated battery. Replacement ordered.

ClassJ

Thats prob about 60% state of charge. How old is the battery?

If the battery was on a tender it should be right around 13v after taken off charge.

My money's on battery. Keep us posted.

Thanks for the link!

Well not good news. I got a new battery and charged it up and no change. In fact it's even worse now. I am still getting the same error messages but now getting a "possible reverse gear fault" or something like that. The result is that the car (PDK) will not even shift gears and the car does not think it is in park even though it is. So the car won't even start. It is just stuck in the garage now. All the lights and displays work fine. I could not find any bad fuses. I will call the dealer tomorrow. It has to be some electrical fault as I am still getting all these seemingly unrelated errors. Trying to be patient, but right now my feeling is just to get rid of this car. Will hang tight though. Massively frustrating though as I had a nice drive in the car and parked it in the garage and the next time I started it all hell broke loose. It was still drivable then but not even that now.

So after you posted you said you were going to dealer. Did you go? So what Is the plan now? Flat bed pulls up and drags the car out of garage? Car is in garage? You have rodents?

dflowerz

I just posted the above a few minutes ago. I will call the dealer tomorrow and hopefully get a plan.

Good luck. Maybe set a few rat traps and throw some moth ***** under the car. Maybe this is an electrical issue from nibbling rodents? Keep us posted.
