Hi.

I've been driving my brothers 07 Gti the last week and have received the coolant warning light twice. On Tuesday I pulled over after 5 min driving and checked the level and it was between max and min level. When I restarted the car, warning gone.

Received the warning again today. Checked level as soon as I backed out my drive and on level road. Again, level the same. So I drove approx 30 mins and monitored the temp which did not go above 90. Happened to turn off the car at a set of lights and on restart warning gone. I rang vw service and they simply said monitor it and top up with any coolant from retail auto shops!

Will try to go vw tomorrow.
