Of course, this is a very common problem. The honking comes from a failing diverter valve. Once it is totally gone so will your boost. You can replace it with this one. ECS tuning has it on Sale at this time. It is an OEM Diverter Valve and will work with any 1.8TOkay, almost everytime my turbo kicks in it makes a honking/buzzer noise. If you kick it on down it stops, but I have noticed that it is getting worse.
Any clue what is happening?
What type of Diverter Valve did you install? Stock OEM?Okay I changed the Diverter Valve and that helped some, but I still have the noise. It seems to come into play around 3,500 RPM. Any other suggestions?
