No heating in my 06 Passat 105bhp ,I only have heating when I Rev her up to 2000 revs and hold it At that for ten minutes . The coolant goes away down in the header tank , changed the thermostat there was white gunk in the pipe and still no heating , cars going up to 90 degrees and above what do you suggest is wrong ?
