It's not a special VW Tool. Many makes of cars require the same tool to retract the pistons in the rear calipers.
The tool sets come with adapters to use the tool on many different makes of cars.
You can usually borrow to tool set from a auto parts store with a tool loan program.
Or you could just buy the tool set. Harbor Freight has them for $40 (use a 20% Off Coupon from a magazine or the Sunday newspaper to lower the cost more).

if its a turn in style piston, I use an adjustable angle grinder wrench. like this one but available anywhere tools are sold.
