Hiya Guys
2020 Polo Match 55000. Today (hot day) engine warning light on!
Car running without any misfires, or any noises.
All levels correct.
Got home, and lifted bonnet - no visual problems - heard what sounds like a very quiet electric motor running (very low noise) rad fan not turrning.
Any immediate ideas come to mind - . When car cools down will check the fan connection. BUT will fan failure be described/included as a legitimate cause for engine light
Ideas welcomed
Thanks

Read error codes via OBD

Anything else is guesswork

OBD is the first step if you can't see anything visually.

As you say OBD is the only way!
when connected - full search revealed the air intake purge sensor at fault. Disconnected, then reconnected - fault then cleared since no re occurace.
Must but one myself - any recommendations for simple but inexpensive unit?
Thanks
