Hey, i had my water pump changed about 5 months ago and when i first got it back the temp warning light came on every time i started the car up. Took it back to vw and the guy said the wtaer just needed toppin up which i did. I has been fine since but this morning it has done it again. It was a cold mornin this mornin and in was wonderin if the temp warning light comes on if the water goes below a certain temp, i dont think the water needs toppin up because it on the max mark when cold.
Any advice would be appreciated.
