What P2B32 means
With P2B32 the controller finds that the second radiator fan keeps operating, or does not change state, against its command. On conventional cars this usually traces back to a relay stuck closed, a fan 2 control line shorted to its active level or a module that has lost control of the motor. Audi documents P2B32 for the RS e-tron GT and the plain e-tron GT of model years 2022 to 2024 as symptom 59342 in thermal management J1024: debris entering via the wheel housing liner blocks the fan, which leads to poor cabin climate, reduced drive power or incomplete charging; the cure is a revised fan, shroud and liner set for the affected side. CARB requires fan outputs to be checked for correct reaction to commands. A fan that never stops may also drain the 12 V battery. P2B31 covers fan 2 doing too little, P2B30 fan 1 stuck on.

What to do next
- Note P2B32 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
