Help required please!  My Octavia VRS Limited Edition Estate bounces about the road with driven at high speed.  It recently passed its MOT with flying colours but sometimes it feels like it's about to flip over.  I love my car and want to get this resolved.  Any help would be greatly appreciated.  Thanks.

Id check the shocks haven't leaked all the fluid out or the springs haven't broken. 

More testers aren't all as good at checking as others.

My Octavia used to feel shall we say rather loose at speed over uneven roads. This was at 50k miles and there was no leak from the shocks and passed MOT no problem. Decided to fit Bilstein B8 shocks onto the standard springs and now it is a different vehicle. Such an improvement you can push harder with far more confidence, and it does not wander over uneven roads any more. Mind you, it never felt like it would flip over as you describe.

Sounds like your dampers are shot 

I had this exact problem up until last weekend when I fitted new rear dampers. When I took them off the drivers side rear was completely broken and did not damp at all lol.

Thanks.  I'll check the dampers.

I'd agree you probably need new dampers (based on experience on probably some of the same roads).
