I have a new 2011 Jetta Sportwagen and have noticed that sometimes after I shut the car down after driving up the hill to my house there is a strange noise that appears to be coming from the exhaust valve (behind the NOX catalyst). Sounds like it's cycling, making a clicking/high pitched sort of sound. Is this normal?
Also, does this car have a coolant circulation pump like the 2.0 FSI does? Is there any need to let it idle after a hard run or is the coolant circulated automatically?
thx,
Dan
