Okay so i been battling a noise for some time now and dont know where to go with it. I get this wierd humming/trumpet noise under boost/load. Since the noise started I replaced the turbo, downpipe, Catback, n75 valve , intercooler and all the piping. Both pcv valves. And diverter valve. Using vagcom my boost is matching the specified. I get A p2293 code. Replaces hpfp. Fuel filter. And fuel limitation valve. Fuel request at full boost is 104 bar and car only makes 91 bar. Not sure if they are related. You can hear the noise out of the exhaust. Plz help
