The car is a 2013 VW Passat TDI. The problem is an odd one - sometimes the passenger side corner light is out. And sometimes it isn't. When it is out, the trip computer will turn on a warning light and give a message. But then when I get a chance to look at it, the light is back on like nothing happened. Anyone seen this sort of weirdness and have a good suggestion for where to look first?
