Hi, we have a 2012 VW polo and the dash light came on yesterday indicating there is a problem with the lights. I checked all the lights and everything appears to be working fine except when indicating left, the indicator light on the dash is flashing fast - this would indicate that one of the actual indicator bulbs has gone, however, all the indicators are working correctly. Any ideas? do these things have a flasher unit that may be faulty??

Thanks
Ben
