I just saw a 2007 GLI with 120,000 kms that I was interested in purchasing today. There were 3 issues that I need help with:
- Upon launching the car (gas pedal floored) I could hear some kind of grinding noise from the mid-rear section. I could not hear it anymore after trying a few times
- The car made a very brief rattling noise every time it started moving (gas pedal pressed normally). The owner said it might be because of the DSG transmission which mimics the behaviour of a stick shifter during depression of the clutch
- There was a kick every time I backed up (gas pedal pressed normally)
I am mainly concerned about the intermittent noise, but thought to throw in the rest just in case. According to the owner the car was parked for a couple of days, so I'm guessing maybe it needed to warm up first but I can't convince myself.
What are the possible causes of the intermittent noise?
