New to the forum have a mk4 r32 HPA DTM kit just installed, car is driving great except for a whistling noise that I'm unable to identify. Checked the hoses for an air leak, removed the air filter and MAF and the noise it STILL there. No error codes. Makes me think it must be coming from the EFR 7670 turbo.
Contacted HPA and they say this is not a normal sound but they're unable to give any useful suggestions for a fix. If anyone can offer any ideas it would be much appreciated!
