I drive a 3 litre TDi EZ 2010 model 2011. After the heat a few weeks ago my air conditioning system completely failed, I drove like before with open windows and sliding roof. Also quite nice again, but at 36 degrees the discomfort prevails. Anyway, that was a FEHLER. Since then I have noticed a metallic cackling when steering (at low speed or standing) and that my brakes squeak sporadically very loudly. I have read a thread about it here, unfortunately not found any more. The brake was built apart before and after the cracker and a foreign body was removed. Now the previously noticed grinding noise is gone, but the cracker is not. Who can please give a hint about it? Only on the edge: I was yesterday in the wash road and immediately afterwards refuelling. After opening the tank cover I saw the swimmingpoo I was able to solve the problem myself by removing the water with a syringe (for ink to refill on printers) and drilling the drain with a toothpick again. I hope there was no water in the tank;-) Ah Diva, with you it never gets boring.
