Wee update recently, got a bit of a knocking develop on the back left, hoped it would be a bush since it is still in warranty but after a look, it appeared to be the dampener so ordered a new one from bc.
It arrived yesterday but never managed to fit it due to working a bit later but got it fitted today, when I lifted up the boot after I removed the dampener oil everywhere so at least it confirmed that it was mullered. Replacement dampener was 100 so not great but not to bad and was quite quick to arrive since it had to come from the factory like.
