will go to dealer thursday when I can get the car in for service -

code isn't known to the internet or the service manager

2022 911 TurboS Cab

we'll see how this goes

code P0D85

{sigh}

I looked it up - "insufficient ADM" so now you get charged an arm and a leg for diagnostics outside of warranty lol

You need to give spec of your car. Stock? Mods? (Exhaust? Cats?)
Some of our codes are P0420/P0430/P050 all related to aftermarket cats/exhaust that can be cleared with standard OBD scanner

That sounds like a voltage related fault. Was the car sitting for a little while? Do you have the open recall for the ground cable?

GoBlue!

I had a lot of low battery related faults out of the gate (PPF killed the battery). Took it in to service who cleared the codes and trouble free over 7k miles at least related to that.

easy for me since the dealer is close by but I can appreciate the frustration.

zero after market mods - zero - zip - zilch - nada. 100% factory stock.

consider yourself lucky
Ive got less then 700 miles on my car (took delivery Nov 30th) and its been back to my dealer on 2 separate occasions for the same 2 faults.
Seatbelt and ACC which are related.
Hope to get it back tomorrow

code is elusive - dealer had to involve Porsche Germany to find out what it meant - and even Porsche Germany pushed back and said there is no such code - dealer send them logs from Porsche service computers - porsche Germany said "omg - let us get back to you - yeah that's a new one on us"...OMG what are these people doing?

came back with…

"resistive levels out of spec at battery for cold start"

code has been cleared and has not recurred

no one has any idea what the code actually means, what caused it - or what needs to be "fixed" if anything - vehicle will be returned to me tomorrow - no action was taken by service team on this issue - and no advice will be given as to how to avoid it in the future or what it means.

I'll update once I have the paperwork if there is anything interesting in the service write up.

It feels like a low battery has caused the cel to me. Amazed Porsche don't know.

It will be fine, I paid 50k for engine work and my car came home with CEL, that was on top of the 276k for the car, so yes it is ANNOYING. So if you want get a code reader, many can reset annoying CEL's, I took it one step further and purchased to Porsche service software from that really big country, it saves me from taking my car to the dealership. Some times there are stored codes from the factory, and once cleared they never returned, my car had several.

P0D85 – Battery Charging Output Voltage Too High
Two thoughts:
1.) Did someone attach a Battery Charger to the car that allowed an application of more than 18 Volts? FWIW, 18 Volts is the industry standard limit for most (but not all) Battery Chargers.
2.) A fault in the Voltage Regulator, integral to the Alternator or discrete in whatever on-board computer has this management function.

daveo4porsche

no battery charger has been attached - CEL showed up when starting the vehicle one morning.

Angryinch

Lithium ion battery, make sure you have a lithium charger on it when the car sits, these batteries do not like to sit around and are quite expensive.

Could be a voltage spike somehow when it started up.

daveo4porsche

grr another CEL no reader with me - will drop at dealers today see what they find - grrrrrrrrrr

Engro

Let us know what they find. I know you indicated this is stock car. Some of us at least we know why we have CEL (Aftermarket Cats) and has to be frustrating constant CEL and stock car.
