I went to look at a car the other day and I have now seen a few. This one how ever when idle has a strange ticking noise. I have read about the cam belt tensioner on this forum but the Cam belt has recently be changed and the YouTube video someone had posted it sounds a bit too high pitched for the noise I am hearing. Also a family mechanic who I trust has looked over the engine bay and said it wasn't the cam belt tensioner. The owner didn't like the idea of him taking off the plastic cover though to have a further look.
They owner took it to the VW garage and they said its just the "high pressure" injectors when the car is idle. I am concerned as I haven't heard it on any other Golfs I have seen. They have accepted a good price for the car and everything else is top marks except this
