Hi Jeri,I have a Rialta 2000, and I had this dash light on for twice, each time I went to the VW dealer and he fix a kind of computer on the engine and the light goes off each time. The light came on a third time and he checked the spark plugs and one was defective, they change it and now the light is OFF and this for 3000 miles from that time. ?????? Good luck.
