Hi I have a RCZ 2013 hdi, I have put in a new stereo a pioneer touch screen, however now the engine light is on and the parking sensors are not working, I have plugged it in to a computer and it says faults as it’s not connected to the original computer how can I rectify this I purchased all the correct leads to connect the new stereo

Its possibly it may not be compatible with Peugeot software as in lack of communication with can bus errors this happens very often with some aftermarket units you may need to do some homework?
