My blinkers stay on and dont blink just solid green light.
Left blinker goes 100x faster than the right. Bulb replaced twice and it still goes out.

My turn signals work only sometimes. They work when I first use them, but the more I use them they stop working?

Turn signal does not work, this needs to be repaired by a VW dealership at no cost to the customer. The internet is full of people with the same problem with their VW product, its not just the beetle. I am very disappointed with my car, its very hard to maintain. Parts and service are priced out of my range.

Turn signals just quit working - I turned the car off and back on, then they started working again...
Haven't had it fixed yet as it is intermittent. This will usually occur after a heavy rain.
