thegrouch 10 Posted October 11, 2011 The other day I noticed the temp gauge on my 1.9 sdi caddy was sky high and the low coolant light came on. I replaced the water and everythings been fine since until 2day when the gauge has stopped working completely. Thought it might be a sensor. Anyone any ideas which 1 or anything else it might be?
