My 2012 Octavia 1.6 TDI started making a whistling noise after I got the EGR valve replaced. I noticed the noise literally as soon as I got the car back, and it wasn't there before. First the mechanic said that this was normal and they 'never sound the same again anyway'. Now after several months I asked him to look at it again, and now he tells me that he thinks it's the 'turbo' but that 'it does not necessarily mean it on the way out'. Something tells me he's lying and he doesn't want to fix it? It just seems too much of a coincidence that this only started after I got the EGR replaced. Any ideas what could be the problem?
