Hi
I have a problem, hope someone can help.
I have a VW passat S TDI 110bhp and during the winter the windscreen was misting up no matter how hard i tried to demist it using the climatronic. This seamed to disapper when the warmer weather appeared. A month ago the coolant level light has coming on and warning of low collant. So i filled it up. This is happening quite often. The last week or so the temp gauge on the dash normally sits at 90 deg. When I'm driving now it sits at 90 then falls to nothing then back up to 90 again. This happen about 10 times over an hour journey. Also when i check the coolant after an hour journey, its below the minumun. I refill to the max and carry on for another hour, when i check it's back to the minumun. If i look under the water tank it is soaking so most if not all of the water is coming out of the tank. The tank has been replaced but is still doing this. There must be something creating excess pressure that is making it come out of the tank? Also today i was driving with the climatronic on Low and then turned it up to 21 deg. Steam, or at least that was what it looked like, came out of the vents. Smelt funny. Steamed up the windscreen very quickly.
Has anybody any ideas of what may be wrong.
Head gasket? Heat exchanger? Evaportor? Temp Sensor?
Any ideas are greatly appreciated.
Thanks
Gordon Wilson
