Gark 0 Posted February 25, 2007 Report Share Posted February 25, 2007 Hello! My Vento vr6 makes a noise like an out-of-tune saxophone (particularly when letting up on the throttle), which I am informed is probably to do with the ECU. Has anyone else experienced this, and if so, is there an inexpensive way of curing the problem? Link to post Share on other sites

Gark 0 Posted February 9, 2008 Author Report Share Posted February 9, 2008 In my case the noise like an out-of-tune saxophone problem was solved by having the vacuum control unit (vcu) replaced! Let me know if this is helpful. Link to post Share on other sites
jesterwalker69 0 Posted February 9, 2008 Report Share Posted February 9, 2008 My golf has developed a whistle, occasionally! Sounds like the whistle of a supercharger and mimics the pattern. i.e. gets loud and higher pitched as i accelerate and then drops etc when i'm slowing down.Can anyone shed any light on this?P.S sorry to hi-jack the thread!

sticks 0 Posted February 9, 2008 Report Share Posted February 9, 2008 mine seems to go when climate is on too or when cold engine, Link to post Share on other sites
jesterwalker69 0 Posted February 11, 2008 Report Share Posted February 11, 2008 No not the sound system. I popped the hood and fiddled with my MAF (the wiring into the plug is slightly lose so she idles lumpy every so often) and also had a fiddle with the fabric bit of hose that goes right next to the manifold on the right hand side. Then the whistle stopped and hasn't come back since! Link to post Share on other sites
