I would start with the basics; check the wiring harness to the ABS module for damage (plug, pins bent, wiring harness cut, insulation damaged etc.).
If you have VCDS; you can try to read the measuring blocks and try to communicate with the ABS module, to troubleshoot the problem.
NOTE: There was a recall; on some of the New Beetles for the ABS unit itself (call your dealer; see if there is a recall for your car; be sure to have your VIN # handy).
The board; that the connector is plugged into, was known to have wiring failures in the VW Mark IV ere cars. Because, of the high cost of a new one; there are many companies, that will rebuild/repair it for a reasonable price. BBA REMAN on eBay; is one of many, that offers this service. This also; has the added benefit of not having to do any coding, matching or messing with bleeding of the brakes, if you replaced the whole ABS unit.
The rebuild service price; has come way down and is less than $100, you might contact these vendors and see what they have to offer.
