I have the Durametric software installed on my laptop.
Leading evidence: 'Install on my laptop' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'related' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Disconnect sensor would cause an error' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

This issue seems to have happened in other 996s and some owners have reported that the issue is related to the engine compartment temperature sensor not having been installed properly.
Replace coolant reservoir and the coolant level probe

The coolant reservoir and the coolant level probe were replaced recently.

The engine compartment temperature sensor and its grommet were also replaced recently.

The temperature was 130F when I started the engine, because I had used the car a couple of hours earlier.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

The red light on the coolant temperature gauge of my 2000 6 speed 996 is often flashing slowly (0.5 Hz) for no apparent reasons. This started 4 or 5 years ago. Initially the light would come on only occasionally and just re-starting the engine would turn the light off.
More recently the light has come on usually after 15-20 minutes of driving. If I stop, turn the engine off and re-start the engine, the light may not come on again immediately, but it will soon. There are exceptions to what I described above, but they are not frequent.
It is my understanding that the two conditions for which the light flashes slowly (0.5 Hz) in a 996 are the following:
Engine coolant level in the reservoir too low
Engine compartment temperature too high
But all the engine parameters appear to be normal. Experienced Porsche mechanics have looked into this and have said that there is nothing wrong with car.
The coolant reservoir and the coolant level probe were replaced recently.
The engine compartment temperature sensor and its grommet were also replaced recently.
This issue seems to have happened in other 996s and some owners have reported that the issue is related to the engine compartment temperature sensor not having been installed properly. Mine appears to have been installed properly.
Any idea on what could be causing the problem?
Thanks
Buy a cheap WiFi or Bluetooth ODBII reader and download an app like DashCommand or Torque. You can monitor the engine compartment temps in real-time. That way you might be able to eliminate one possible cause. Also they're great to have on hand and take up no space.
Unplug onr sensor at a time amd see if the light stays off. This way u can isolate the sensor. U may also have a chafed wire that is grounding out and causing it to trip. Once the light is activated u have cycle the key to turn it off even if there is not a continueing issue. So if the computer gets a quick randum signal it wont turn off.
Also do U have a uaos? If so some of the early oil sensors glitch and cause the light to activate. Skip has an updated sensor.
Thanks for your suggestions.
I have the Durametric software installed on my laptop. This morning I used Durametric to monitor the engine compartment temperature in real-time. The temperature was 130F when I started the engine, because I had used the car a couple of hours earlier. The temperature started going down slowly as I drove on the freeway. The red light on the coolant temperature gauge came on after about 5 minutes. The temperature in the engine compartment kept going down and appeared to be stabilizing at about 100F. I did not notice anything different in the temperature at the time the red light came on.
At this point I would think that is more likely that the problem is related to the coolant level sensor.
Thanks for your reply. I was wondering if disconnecting a sensor would cause an error that affect the way the coolant red light works. Any idea? If not, it seems to me that it i certainly worth trying.
I do not have uaos.
Sounds like you may have air in the system. Lift the wire bail on the coolant tank and run it that way for a few days. After I installed the UAOS (lost a little coolant doing so) - had the slow flash. Kept the bail up and frequent checks of the reservoir, finally worked all the air out. No more slow flash. Lowered the wire bail - no more issues.

Tom,
I tend to agree with you. Could you please advise what is the wire bail? Is it inside the tank? How lifting the wire bail allows the air to go out?
Thanks
The black thing on the coolant tank in the engine bay. Rotate the wire bail so it lifts the valve. As said, a couple of days or at least 4-5 cold to hot, then hot to cold cycles should do it.
