2011 Volkswagen Jetta TDI: Turn Signal Death Spiral
January 30, 2012
I find one-touch / three-blink turn signals, like those in our longterm 2011 Volkswagen Jetta TDI, useful and handy. However, such a feature should always include a 'cancel' function, which is something our TDI lacks.
For example, a car materializes in the adjacent lane just as you tap the turn signal lever down for a three-blinker. Wanting to cancel the turn signal, you quickly tap the lever the opposite direction, but the Jetta three-blinks the other direction. In desperation you tap the lever down once more... congratulations, you're in a turn signal death spiral. It happened to me twice during the weekend. Argh. Surrounding cars probably thought I was messing with them. Or on drugs. Maybe both?
As I'm typing this it occurred to me that it's possible our TDI has a cancel function if you tap the lever in the same direction. However, I'm one foot out the door for a flight so will have to look into this at a later date. Or perhaps one of our trusted readers knows the answer?
