[928uk] had or needs engine mounts ?

[Simon Crowe]

Hi Duncan,

The S4/GTS mounts are hydraulic, unlike the earlier ones which I believe are solid. 

I have the same issue on a Mini where the hydraulic mount has failed and it’s causing all sorts of vibrations and even the occasional knock.

They are great when new, but I understand it’s the constant exhaust heat, plus heat cycles, that cause them to fail.

Cheers,
Simon.
