Yeah, the light often means that the coolant level is low due to high pressure... Basically as soon as I use full throttle in my car once warm, the light flickers on... The Ph2s are terrible for it I've found, Ph1s won't usually bring it on unless it's literally EMPTY, but the expansion tanks in the Ph2s seem to bring it on every 30 seconds if the coolant pressure builds.
