Problems with ABS/DSC system, vibrating steering wheel and failed power steering in the 2012 VW Tiguan

I have a golf5 fsi on the steering angle sensor it has no spring or clock it's just a very small black box that is next to the rotary switch and connects to the steering column module rectangular black and yellow box.

Inspect the connections between the steering angle sensor and the steering column module for any loose or damaged wires. Ensure that all connectors are securely attached. If everything seems fine, consider checking the steering column module itself for faults, as it might be affecting the sensor's calibration. Let me know if you need further assistance or have more questions!

And also, when I turn off the engine, I always feel a click from the steering wheel, which always forces itself to the left of the klic, and the steering wheel turns slightly each time the engine is turned off.

(Translated from French)

The clicking sound and movement of the steering wheel when turning off the engine could indicate an issue with the steering column lock mechanism. It might be engaging or disengaging improperly. Inspect the steering column lock for any mechanical faults or misalignments. If the issue persists, it's advisable to have a professional mechanic examine it to ensure safety. Let me know if you have further questions or updates!

Ok I made a text by unplugging the gateway box and when I start the original error red steering wheel, airbag , beep beep beep exactly as at the start surged,

(Translated from French)

This suggests there might be an issue with the gateway module or its connections. Ensure that the gateway module is properly connected and inspect the wiring for any damage or loose connections. If the problem continues, it might be necessary to have a professional diagnose the gateway module to ensure it's functioning correctly. Let me know if you have any further questions or updates!

My immobiliser active comes up on the screen and I can’t start my Bentley Continental Gt. Please help I can’t find anyone or anything that can help me start it

First, try using a spare key if you have one, as the issue might be with the key's transponder. If that doesn't work, check the battery in your key fob to ensure it's not dead. If the problem persists, inspect the fuses related to the immobilizer system. If you're unable to resolve it, I recommend contacting a professional mechanic or a Bentley dealership for assistance, as immobilizer issues can be complex. Let me know if you have any further questions or updates!
