just thought id update you guys on my progress so far.
after the farce earlier with the bumper, and the slight removal of the loom insulation, I had another go today
removed the bumper, and re coated the loom with tape , inspecting as I went.. nothing un towards. then removed front pdc's from bumper and xhange each in turn with a new pdc sensor, nothing , still broke , thought sod it , and put it all back together and parked car on road . then remembered one of the members on here saying the car bongs when the key's in the ignition .
hmmmm I removed the drivers kick plate where the gong is and have a guess what I found ,
a bloody connector off !!!!!!!!!
re attached I now got working pdc's !!!!!!!!
victory is mine !!!
