P30EF-00 Code

[Ty88]

I have had no issues with my car at all - 5 bw, 6 spd 2023 6200 miles. When I scanned the car several months ago I got a P30EF- 00 engine cooling fan speed too high. The code would not clear. Then several weeks later it was gone. Scanned car today and it is back. Anyone know about this code or having similar issue? Thanks.

Haven't had something like that on my Blacking but in the past that usually indicated too much resistance/voltage going to the fan to spin. Our cars may be more advanced and have a separate sensor but either way sounds like replacement of the sensor/fan assembly under warranty is your best bet.
