When driving down ramps on multistorey car parks, the octavia wont stop squeaking. Any ideas?

sure its not the radiator mountings...very common by all accounts.

I go for radiator mounts too - try opening the bonnet and getting an assistant (wife etc.) to slam the passenger door really hard while you have your head above the radiator.

Should be easy to hear the noise.

Another good way to replicate a squeak is not to bounce the front end but get the assistant to sit on an open tailgate and bounce up and down - while you have the bonnet open.

Hmmm I have developed a bloody annoying squeak too. It's doing my nut as it doesn't always happen. I will try this radiator thing, with the tail gate as I was bouncing the front as that sounds like where it is coming from.
