Hello audi people.i have an a3 1.6 on a 2002 plate.car has been ok past few months however its developed a really weird nose.on turning right at roundabouts the car seems to misfire and the seems to be a jerking and grinding noisebcoming from the front left.it does it on the same 2 roundabouts in my town.on driving straight or left the car is perfect.i plugged my cheapy fault code reader in and looked up the code.the code is a faulty power steering pressure sensor.surely this would not cause this annoying misfire/grind/kangeroo would it?any help or ideas what this could be would be gratefully aprriavted.thanks guys.
