9 systems errors at once

[Tighlines]

Yesterday I had 9 systems errors pop up at once while driving, the audio source even cut out. All errors said that the car was ok to continue driving but that it needed to be serviced asap. The driving dynamics of the car also changed when the errors popped up. Braking and suspension were the most notable. I drove it another 70miles after the errors to get home and it made it but all errors are still there this morning. The car successfully charged last night and I was hoping that the charge and locking overnight would have cleared the errors but no such luck. Has anyone else seen or dealt with this?

Can you check your battery terminals if they are secured tightly? A wide range of errors can come up when the 12V is drained or disconnected and car momentarily switches to the HV battery as failover. The errors will persist until the fault codes are cleared, ex. via OBD tool or MapEV Diag tool

The red cap was completely off but I dont think that affected the battery. The other connection i could see was firmly in place. Is there another hidden connector?

What you see there is the remote terminal post (meant for jumper cable connection). The black plastic cover can slide upwards to expose the actual positive terminal. See: https://www.taycanforum.com/forum/threads/routing-ctek-cable.23342/#post-517913

Use gloves and check both of those terminals are secure.

When you’re done, replace the cover and cover the remote terminal post with the red cap. It’s unlikely but a foreign object can touch on that post and to a grounding/chassis point and cause an electrical issue?

Everything seems to be firmly in place. It does make sense that is it something of that nature. How could so many different, unrelated areas of the car go into fault at the same time...? I have a service appt on Friday. Thanks for your guidance.

MapEV Diag if you want to actually know what is wrong with your car.

My experience when my rear motor was failing was that the car threw many codes that showed up when I scanned the car with my Foxwell i70BT scanner. I got no error messages displayed. Let the dealer look at it if possible. I was glad I had bought the extended warranty. Good luck.

Hello, i have the same error did this get fixed and what was it if you don’t mind me asking

Hi,
So, a wiring harness became unfastened and rubbed against the wheel until wires were exposed and it was causing a short. That short caused all sorts of unrelated faults. Once the harness was replaced and refastened, everything cam back online. Fairly simple really.
Good luck

By any means did you get an intermittent transmission error but the car drove fine

for me its the left wheel speed sensor and level sensor causing errors, but could be the same as yours with a wiring issue

I dont recall getting a transmission error. Of the 9 errors (all listed in pics above) maybe only 2 were related to the actual issue and the car did drive but it was not fine. It was almost like the power steering and brakes no longer worked, it felt like it was rack and pinion steering.

Its weird i also get an intermittent transmisson error, car drives fine once cleared, but once you hit 60mph which the car i think lowers at that point i get all these errors,
In diagnosis it looks like abs sensor and level sensor on the left but changed the abs sensor no difference.
Cars really floaty once these errors come,
Just hoping its not the motor or transmisson

Weird sums it up. With these cars being so electrical/digital, it is impossible to diagnose issues. It could be so simple and minor or major at the same time.
It sounds like Porsche can't figure it out...?
