Default reverse parking sensor issue

Got a bit of a issue with parking sensor, today ive replace a sensor that wasnt clicking.. rest of them was clicking..
before i replaced the bad one i had a continuous tone for around 10 seconds.. now ive replaced the bad one ive no tone at all.. ive got a left lights on tone, but no reverse tones... all sensors are clicking, the reverse switch was only replaced less than a year ago so i dont think its that.. i have reverse lights

can someone point me in right direction to solve this issue plz...

Btw its Mg ZT 160+ V6 Pre Facelift

much appreciated

As your sounder is working and your sensors are OK ie live - i would look at the connector block between the parking ECU and the sensor loom - the 4 sensors lead into the connector then out ot your parking ECU . I had similar issues 2 years ago - the long tone as well as silence - there was corrosion on the wires and terminals in the connecting plug.
