Slow brake pedal return/ possible brake vacuum leak or check valve failure.
Hello I wanted to run a question by some of you VW and Diesel guys out there.
As I drive my car I can hear a sucking sound coming from the engince bay.
Does not sound like the turbo, and when i use the brake pedal it is slow to return
to the top position, there for giving me a slight brake drag effect. It has the DSG
transmission so if the pedal is not all the way out then it will not spart to pull. If
anyone has been down this path please give me some incite. I would like to try
and fix this with a little more accuracy. Thank.
