ChargerCharger 10 Posted March 25, 2013 Thanks , looks like the yellow is the one I need . Anyone know how I test the water gauge inside ? Quote Share this post Link to post Share on other sites
nrc 0 Posted March 26, 2013 The easiest way is to run the engine up to temperature and compare the gauge reading to the oil temp from the MFA; they should be about the same. You can also read the value from the blue sender with VAG-COM/VCDS. Quote Share this post Link to post Share on other sites
