Audi A3 8P 2.0 FSI: Persistent Firing Issue, P0341 Error, Camshaft Sensor A B1 - Solutions Needed

Hi. I have a problem with the car as above. The car fired in the garage by touch, I went to the store and after a while the car did not start, i.e. it was spinning and not smoking. After disconnecting the battery for 3 minutes, the car smokes to the touch and may burn for several days. Recently, the problems have intensified so I went to diagnostics and after removing the errors, the car burns to touch, but after driving a few kilometers the problem returns. The error that has been removed and that appears constantly is P0341, i.e. no communication with the A B1 camshaft sensor. Sensor replaced with Bosch and problem not resolved. Briefly: the car starts hard and often only turns and does not burn. Can someone solve the mystery?

It may be the fault of the electrical system - no power supply to the sensor or a broken signal wire between the engine controller and the sensor.
There may be a problem on the mechanical side - problem with the tensioner or timing chain - transmission between the shafts on the gearbox side.
It could use a detailed description of the errors that have been read - not some guesswork.
