they're not TDI exclusive, but Eric and his crew are reliable, honest and back their work. I had to have my glow plugs replaced (all 4 for about $300 total including diagnostics) and 2 went bad within 500 mi after replacement, no questions, no hassle, replaced at no charge and the warranty still stands - 6 months or 60k mi.
Highly recommended as a place for emergencies or for maintenance you don't have the tools to do.
