This thing is killing me… I have a 2007 passat wagon 2.0tdi 103kw (euro spec) and can’t figure out my coolant issue. Long story short… car will drive with needle dead center… then randomly climb for about 30 seconds, before returning back to center … after this event when I shutdown and open up the hood, it has purged most the coolant out of the expansion tank…
additionslly, heat in the car is marginal at best, oddly the leftvents are better and the furthest righ vent is like air conditioned.
Stuff I checked:
1) heater core flows fine when flushing it…
2) no real bubbles in expansion tank, removed hose from engine and constant return of coolant back into the manifold
3) no smoke or intermixing of coolant / oil
Any help would be greatly allrecieted
