Alfa 159 TBI TI Squeak Tip
If when changing gear or going on and off the power you hear an annoying mouse like squeak then do this.
In the engine bay to the left above the drivers side wheel is the airbox. Where it rests in its mount on the wheel arch is a rubber bush. Lubricate it with a grease or wax type lubricant as this sticks and won't evaporate like wd40. Annoying squeak has now gone and I am a happy man again.
This has been covered on the diesels but not the tbi so just thought I would put it out there :-)
