I replaced my thermostat & temp sensor (green) about 8 months ago on my 02 S3. All was good until the other month i noticed it takes ages to hit 90 & sometimes doesnt even make it on short journeys....but i'm sure it usually does.
Am i correct in saying there is only 1 sensor ? my heater seems to blow out good heat even at around 75.
Really dont wanna have to change my thermostat again that was a headache.
