Hi, I hope some of you folk with brains and knowledge can help on this one. Car is an 2006 2.0 TDi 140 Sportback 1. My reversing sensor is constantly blaring when in reverse and think it needs the wiring looking at. But can I work out were the B*****r is or how to get from the boot area through the trim etc. Any help on locating and getting to it would be so so helpful. 2. I had the car remapped about 6 months ago and am pleased with the performance improvment generally however I have developed a turbo whine which may or may not be getting louder! Can someone give me deffinative guide as to what to look for and should I be very worried! I have also read a little about hybrid turbos. Should i need to have the turbo replaced can you guys tell me what is the fundamental difference as to lazy to read though the 100 or so differing opinions on them! Also any indications of costs here would be great. Many thanks. Phil..
