Quick Answer
Error code POL_DU001 on your Polestar Electric Cars means: Electric Motor Overtemperature. This is usually fixable — see the step-by-step guide below.
Affected Models
Applies to all models
PS2PS3PS4PS5PS6
Likely Causes
  1. Sustained maximum-power output during track driving or repeated hard launches
  2. Motor coolant system underperformance due to low coolant or pump fault
  3. Ambient temperature extremes reducing available thermal headroom for the motor
  4. Motor winding insulation degradation generating excess resistive heat
  5. Drive cycle profile with excessive low-speed high-torque demands overloading motor thermally
How to Fix It
1
Immediately reduce throttle input and switch to a lower performance drive mode
2
Allow the vehicle to drive at moderate speed with reduced load to assist motor cooling
3
If an overtemperature warning persists, pull over and allow the motor to cool for 20 minutes
4
Check motor coolant level and inspect coolant lines for visible leaks
5
Contact Polestar service if overtemperature occurs during normal driving conditions
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
