When you turn off the engine in your VW Golf GTI, the radiator fan may continue to run for some time. This is not a malfunction but a feature.
The radiator fan run-on indicator appears in the instrument cluster of VW Golf GTI after the ignition has been switched off, if the radiator fan continues to run.
Why does the radiator fan keeps running?
The radiator fan may continue running in Golf GTI due to:
- Exhaust gas post-treatment, through particulate filter regeneration, for example.
- Active brake cooling after descent.
- Dissipation of engine heat after high load, e.g. trailer mode.
The radiator fan will turn off automatically after a few minutes of turning off the engine.
