Turned out after all to be the radar head unit, had a small hole, water got in and corroded the waveguide. Still no good after strip down and clean. Hope someone can help with alignment question. I have ordered a working unit from a scrapper but all the info I can find on alignment is from US sites. They state that sensor should be set slightly left of centre, which makes sense for LHD vehicles. My question is, should it be the other direction for RHD or is this correct for all vehicles. Also it states left half of sensor should be covered with foil to reset system, other sites say right hand, anyone any clues on this. Thanks for reading, any advice appreciated.
