Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My car died on me the other day. Turns out my battery was bad so I replaced it. I still had a bunch of lights on the dash including the battery light. I replaced the alternator yesterday and now the PSM, ABS, and brake fluid lights are still staying on. What is causing this? Any help is greatly appreciated
Without a scan for codes, anything would be a guess.................
I had a reader on it today and it is not showing any codes

You need a Porsche specific diagnostic tool..............
The PSM and ABS are sensitive to low voltage. The bad battery probably triggered the faults. For quick troubleshooting I often search with a few key words related to the problem and add, "JFP in PA" in to help filter results.

Usually the PMS and ABS lights turn off by themselves after you drive the car for a while, it seems that the car computer needs to verify first that everything is working properly..
Brake fluid light? What am I missing, here?

Great info thank you I'll do some driving this week!
In addition to driving your car, it would be wise to connect your battery to a charger as not to stress your new alternator. Trickle chargers are a small investment and go a long way.
