Hi, my name is***** fault code is typically caused by bad camshaft adjuster solenoid. For this fault code you will need to replace the driver's side exhaust camshaft solenoid. The solenoid is screwed to the front of the cylinder head. You will need to move the power steering reservoir out of the way then remove the three screws and the electrical connector to replace the solenoid. The part number for the solenoid is 272 051 01 77. The solenoid is commonly referred to as a camshaft adjuster magnet. I've attached a picture of the location below.

I forgot to give you the price. The magnet retails for $30.
