What are the steps to timing a 2001 VW Beetle 2.0?
Cost to change timing belt o 2006 beetle diesel
$90 bones
if you are talking about the beetle bug there is no timing belt. the cam is run off the crank gear to the cam gear.
if it has the 2.0L it is ran off the timing belt
Timing belt is not usually a job you do yourself unless you are somewhat mechanically inclined. A serpentine belt can be changed easily but the timing belt is internal and usually requires the waterpump to be changed as well. My advice is to find some videos on YouTube or a vw forum.
If I remember correctly the dealer told me it would cost ~$550.
