Hello , thanks for your question in the autoaid Community.
Your both described fault Codes means: 1.) 9336 The component N49 (steering angle sensor) is defective.
2.) 9183 The resistance of the ignition circuit with the component R46 (ignition pill belt buckle driver) is too large.
1. You have to renew the steering angle sensor behind your steering Wheel. This part is broken inside.
2. In the most of this Problems are the belt buckle is faulty.
But you could look under the seat and check the wirings. You also could check the contacts and measure the lead resistance to this belt buckle if you have a wiring diagram.
But be safe its an pyrotechnic System, better let it check from your dealer, when you have no Knowledge of this System.
