I'm starting a new session on my 2010 xkr that you have…

It's a constant high pitched beep beep beep error tone when the car moves forward or backward and continues until the car stops. Since I disconnected the park aid module ,now when I start the car the display screen says that the park aid is not available.
One mechanic said the beeping sound was an warning due to the crash sensors needing to be replaced because the car had been in an accident although the air bags were not deployed.
Any response on the other questions?

The air bag light is always on.
When is it required or necessary to replace the crash sensors after an accident and please address my questions re the ABS and TPM.

RICHARD THIS IS A COPY OF THE FULL FIRST MESSAGE OF THIS SESSION WHERE I ASK QUESTIONS ABOUT THE ABS AND TPM.
Richard I'm starting a new session on my 2010 xkr that you have been advising me on. As a review of our correspondence will show the car had been hit on the front left side, and in repairing the damage I gave it the 2012 face lift with the newer front bumper, fenders and head lights. As a resultthe park aid sensors are not in the front bumper. As you suggested in our last session I disconnected the park aid module in hope of stopping the constant beeping sound, however the beeping noise continues when the car moves forward or reverse. Could it be an alarm from the crash sensors since the air bag fault is on. Should the front crash sensors be replaced since the car was hit in the front drivers side. Or should all of the sensors ( front and side impact crash sensors) be replaced and if so is there any programming that will need to be done?
Because the brake lights were not working I tried your suggestion and I replaced the brake switch however the brake lights still do not work. Could it be the ABS module since there is a ABS and DSc fault and the ABS module has not been programmed to the car?
The TPM light is on and I am going to replace the TPM sensor on the wheel that was hit in the accident ( the front drivers side). Is any programming required after the TPM sensor is replaced?

Please go back and read the first message in this session. That is where I asked the questions re the ABS and TPMS.
