I have a 1999 New Beetle with a 2.0 liter engine. I had just replaced the headlight and was starting to pull up the driveway when i stalled the car trying to put it in gear on the slope. I turned it on again and heard a loud ticking noise coming from the passenger side of the engine. It was loud enough that I couldn't hear the engine. My VW friend thinks it's the timing belt. But i want a second opinion. Any help would be great.
