Passat tdi coolant problem

Joined: May 28, 2008 Posts: 1

my 1998 passat tdi loses coolant every 2 days or so . there are no leaks and no oil in the coolant. every time i take the expansion cap off to top the coolant up , there is pressure there , even when the engine is cold. i have removed the thermostat , checked the water pump and flushed the system through

Check the EGR cooler. They have been known to leak internally. Take one of
the EGR connections off & you might see moisture in there.
