2013 Audi TT Mk 2 5/5

Instrument cluster dials with intermittent backlight failure. The unit had been with another more local repairer for 2 weeks who failed to find the fault or repair it. ECUs' administrative, online booking process and courier delivery and return system worked seamlessly via DHL. Within 5 days from despatch the unit had been tested, repaired and returned with a lifetime guarantee. That was a month ago and so far so good. Excellent.
