Took the wheel off to have a look and the spring has white and yellow marks - which I think confirms it is 1K0511115BD.

Thanks , really helpful. Is matching wire diameter / length a safe way to work out how close to the OEM part it is? I was looking at these on eBay, not too far off the 1K0511115BF spec you listed above. You think this would be ok?

Yeah I am going to replace the shock absorbers, I already have those. Was an advisory on the MOT so I’m sure they are probably worn out. Think I’ll take a punt on the E/F springs , seems the middle ground

Cheers, had a quick look and the ones that come up when I put my reg in on that site (including the ones you mentioned NCS1140 £18.75) seem to be part number 1K0511115BG. It’s confusing because other sites have recommended 1K0511115BD - which if I’m understanding the last letter codes correctly is 3 levels softer than BG. I suppose I should take the wheel off and see if I can see the colour code of the current springs…

Thanks for your help, is your car an estate? I basically just want to be able to carry passengers without scraping on speed bumps. I’m not often carrying really heavy loads and I’m not towing . Having read this thread https://www.briskoda.net/forums/topic/500864-mk-ii-octy-estate-variable-rate-springs-other-than-bilstein/page/2/#findComment-5656174 it seems like I might want to ignore the 1K0 511 115 BD and get something stiffer? But I’m also reading in this thread https://www.briskoda.net/forums/topic/500864-mk-ii-octy-estate-variable-rate-springs-other-than-bilstein/#findComment-5655975 that the 1K0 511 115 BG is too hard! I found this on eBay which is listed as replacement for 1K0 511 115 BE and 1K0 511 115 BF https://ebay.us/m/CNfvMN . Maybe would be a good middle ground ?

Hi, I’m hoping someone might be able to give me some advice about which rear springs are best for my 2011 Octavia 1.2 TSI estate? I’ve had the car for a few months and generally it’s been great, but if I have passengers in the back the bottom scrapes going over speed bumps. I read on this forum that after 2007 Octavia estates were fitted with softer springs, I’m wondering whether it might worth getting slightly stiffer than the current ones. I’m being told that the correct like for like replacement is part number 1K0 511 115 BD. But I don’t want to replace them (I’ll also be replacing the shock absorbers) and find that it still scrapes over bumps. Would I be better off getting 1K0 511 115 BE/F springs ? Or would the BD springs with new shock absorbers likely solve the problem? Any advice appreciated
