hi everyone
i have a 2001 passat pd 130 that i have to weekly top up with water i do 500 miles a week,and the car is losing water but with no visible signs of a leak,just a few drips on the drive. i have had a system pressure test and the CO checked in the expansion bottle both fine,i taped some tissue around the cap and overflow under the bottle just to see if either get wet,and suprise suprise its the overflow thats leaking out the bottom of the bottle the system is pressurising so much its shooting the water out the overflow,when up to normal operating temp (with engine off)the expansion bottle water is below its lowest level indicator when the cap is released the pressure near enough refills the bottle with water,does this sound like the thermostat is stuck shut or am i being optimistic and its the dreaded HGF l:1zhelp:
