Hi, I have a 2009 c5 2ltr vtr+nav. Had it about 3yrs now. About 10 mths ago started with this really annoying squeak under front right of the car, sounds like an angry mouse, today decided I was going to get to the bottom of this so armed with my tin of silicone spray I sprayed virtually anything i thought could make the noise, strut end, suspension arms engine mountings all to no avail. Is there anyone out there that can stop me going insane!!! Thanks
