Car is being a nightmare! Ahhh!
I was driving through downtown denver two nights ago and a message popped up saying something like "oil level meter failure". When I got home, I turned the car off but all of the different gauge icons illuminated and a second message came across the tach saying "system fault see workshop" (or similar to that). And another message about the rear deck lid appeared as well.
I parked the car in the garage, none of the gauge lights would turn off. I hoped that if it sat for a while they would go out.
Eventually they did, only because they drained the battery.
Now I'm stuck with a dead battery on a car that is acting up
Anybody else have similar issues with their 997?

Never experienced your trouble, but as with a problem on any computer, a system reset could resolve the problem. In the case of a car disconnecting a battery cable may do the trick. When you recharge your battery I strongly recommend a trickel charge. Good luck.

I had a system fault that turned out to be a bad module of some sort and became a three week ordeal to find. This was complicated by a bad cell in the battery I understand that some earlier versions of the 997 have had the frunk control module go bad which seems to be an easy to find and fix problem. Mine is a 2012 997.2 and the service techs really struggled to figure it out.
Good luck.

Could be the forward control unit that controls the lights and blinkers. It is also tied to the truck release as mentioned above and the weird & random instrument light functions you are experiencing seems to be consistent with this issue. Good luck

I got a charge in the battery and took the car for a spin. The system failure message was gone, but then it said PSM failure. After driving it for a bit the message was gone.
When I turned the car off again, the gauge icons remained light again. Im taking the car in on Saturday. Wish me luck and I will keep you guys informed.

It sounds like the alternator cable needs to be replaced. Its a common problem and there is a TSB about it.
TSB 8/06 0101 Breakdowns Due To Loose Ground Strap
Its something about the cable between the battery and the alternator as the battery is not getting sufficient charge.

Could be multiple things. Depending on how you drive the car, some more likely than others.
If you frequently take very short drives of <20 mins, the battery could be low or not fully charging, regardless of age. So I'd first remove the batter and get it checked out. If its ok, then recharge it off the car and then reinstall.
Once the battery is cleared of being at fault, its time to see if the electrical system resets itself with a fully charged battery. If it does, then start watching the battery to see if its not getting charged properly (alternator cable or alternator), or if it is getting charged right, then look for some malfunctioning system that isn't shutting down when the car is turned off. The frunk controller has been known to cycle the latch up there continuously.. which would drain the battery. A faulty ignition switch could cause the car not to shut down (since removing the key should mechanically turn off a lot of the stuff).
Approaching the diagnosis in a systematic way will help narrow down what you need to look at.
