OUCH!! Sounds a bit high to me. Even here, in CANADIAN $$$ (which are worth
about $0.72 US), my local VW/Audi/Porche service garage (NOT factory dealer!)
tells me it costs $75.00 for the ABS diagnostic (that's about $55.00 to you)

Have you checked the ABS sensors at each wheel. One of them could be
intermittently faulty...

Good luck,
