Hi I need advice in this case
F30 LCI front damaged PDC wiring cut and 2 PDC sensors missing I buy two aftermarket and repair damaged wiring. Error cleaning and have errors on original pdc one is heating and doing short one have puncture in front.
 
I buy another  two aftermarket and again error but different 
80322f ultrasonic sensor front outer left , sensor fault: final oscillation time of the diaphragm too short,
after swapping sensors error stays on same plug I triple check wiring 0.1 ohm on wires 14.4v supply and good ground check with bulb, 5.14v on each signal line. Is possible that REM is fried? 
I had f32 on workshop and changed whole front pdc wiring with sensors from f30 to F32 and on F32 works fine no errors and PDC working fine so I assume that sensors and front wiring is ok. Today I dont have time to check F32 wiring with sensors in f30 but is necessary? I think about swapping REM for testing and checking signal wire from bumper plug to rem plug
