My 1994 passat glx will boil over the coolant from the vent on the resivoir bottle, but the gauge inside reads fine. I haven't checked to see if the gauge or its sender is bad, but it climbs normally while the car runs. Any ideas?
Also the passat is hard to start if it sits for a while (couple days). It takes about 20-30 secs of continuous attempts (holding the key) to get it to start. Once it starts, restarting is a breeze with NO hesitation. Any idea on what this could be?
