It can affect performance significantly or could be intermittent. I would start with the basics checking the oil checking the connection for the cam sensor. at worst I would think you need a new sensor which are not terribly expensive.

You can test the sensors with a multimeter as I had to do so on a crank sensor (engine speed sensor) on my old A3 which took weeks to find the problem I was changing all sorts and mine didn't throw up an error.
