I recently brought the car to the dealer for two minor recall items (a fuel line, and flasher switch.) They also did a third recall, which appeared on the work order like this:
B VS RECALL
VS EMISSION SERVICE ACTION ( VS ) 2000 GOLF/JETTA
VR6, JETTA/GTI 1.8T, AND GOLF 1.9L TDI:
REPROGRAM INSTRUMENT CLUSTER SWITCHING RELAY
455 WV2 0.20
I have not heard the noise in the last week!
