How VW Coolant Temperature Sensors Fail ~ Video

Published on June 2, 2015 under Video

Hey everybody, today we are back with another round of failed VW parts! This time we are breaking down the engine coolant temperature sensor, or ECT. You may also see this part referred to as a C.T.S. (coolant temperature sensor). I have put so many ECTs on VWs that it’s crazy. I really enjoyed doing this video. If you have a part you would like me do to a video on, shoot me an email to Charles(at)humblemechanic(dot)com.

    As always great video, I check out the channel just about every day.

    Question, I’ve got a MK6 GIT (CFBA) that has had an “odd” warm up for the past few months. The temperature gauge (and VAGCOM) will rise to operating temperature then after a mile or two drop down to about 150F then slowly go back up to 190F. It’s almost like the t-stat is opening really fast. Should I bring this up to the dealership next time I’m in or is this “normal”?

    Thanks,
