Hi All

Had a major service on Monday at VW van dealer (29K miles), all ok, drove about 10 miles today, parked up, got back in and coolant level warning came on, switched off, started again, same warning, this happened 3 times, checked coolant level and was on MAX as expected after a service, so rang VW assist, as I was speaking to them, started van again and light stayed off so cancelled assist. Over the course of the day it happened twice again, so switched off and started again and all ok. Got a long journey soon so am wondering if need to get it checked or is a known not urgent fix fault ?
 
Once had a coolant light come on,on the way home from having a bike serviced.
Was an airlock in the system..
 
Got VW Assist out and they found it was the coolant level sensor that wasn't fully clipped in but looked like it was, probably after the major service
