Hi, I've just bought a 2017 kombi DSG SWB, completely standard other than sound deadening and carpet lined. The rear is clattering, and I noticed the bottom 3 coils are coil bound, as described above. The van has had sportline springs fitted, by VW. Front measures 410mm from the centre of the hub and the rear measures 430..... strange that it measures higher, despite the fact the coils are clearly compressed.... any advice on what I can fit to the rear to fix the spring issue without affecting the height its currently at? It's only done 54k and has a full vwsh, it's been looked after immaculately, just has this rear spring issue.
