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.

I thought I'd start a new thread on this as it was discussed within the 992 GT3 section but it's better here:

718 GT4 and Spyder also has the cold engine blue light symbol btw which always shows irrespective of mileage and whether the car is run in or not same as all Porsche GTs.
I have a MY2020 718 GT4 and I definitely don't have this light. The image above is from a MY2021 718 GT4.
Does anyone with a MY2020 718 GT4 or Spyder have this blue light appear with a cold engine? I've done just under 5k miles on the car and I've never once seen the light (as it were!) - has anyone else found the same?
I have a MY2021 718 Cayman and I have this blue light too on cold start-up. It usually goes off after ten-fifteen seconds.
Per the Driver's Manual, it signifies the "Heating Phase of the Catalytic Converters. The symbol goes out as soon as the catalytic converters reach operating temperature"
I notice that when the light goes out, the engine idle speed drops and I *think* the exhaust valves close. It’s a fairly noticeable, audible change.
So even if you don’t have the light, I’d expect the behaviour is the same on cold start, fast idle and open valves. See if you can hear the change about 15seconds in. Both cars will be doing the same thing I bet, someone just forgot to program the light.
Yep, the fast idle/cold start/valves open/tractor engine noise is there on startup on my car for sure. Blue light seems to be a MY2021 thing then, although the PEC cars are MY2020 unless they've changed them from the original blue and yellow cars.

Mine has the automatic speed recognition, maybe the speed symbol covers the blue engine light?
Same here Romo, but the blue light is in the lower portion of the display so it would not be covered.
You have a MY2021 though I think, so you should have the blue light? If not, it may be it's not present if you have the speed limit recognition system.

I have speed limit recognition, but get the blue light..

Thanks G, so that rules that out!
Romo - do you have a MY2021 car? I think you do as it's PDK.
I wonder why some cars have it and some don't then. Very odd.

Man, that guy needs to dust his steering wheel column!
Pity he didn't have the leather covering as we could have debated the colour of the stitching and whether it reflects on the dials

Nah. I think he’s a tight so and so.
GT3s had this in the US back in 2014. Their handbook said - while light is on keep revs below 7k. It is an oil temperature light ion the GT3. Assume same for GT4/spyder?
WG said:
According to the manual for the Spyder the blue light refers to the catalysts. It goes out when they are up to temperature.
Cheers. No such reference in my manual, publish date 11/2019. I suspect yours is an update?
