wrong time of day but aren’t these usually £25 - £50 apiece and usually made by Febi Bilstein or Stabilus?
If you take your reg to your local Euro Car Parts or outlets like “struts direct” they’ll give you the correct price
(Long time Estate car addict: I must have replaced half a dozen sets of s211 / S212 /E91 / E61 struts over the last three decades. A very straightforward idiot proof job)
Have a look at this old thread on how to do it:
[FONT="]I replaced my lazy S211 tailgate struts today. Here are a few notes which might help you if you are considering the job yourself. It took me about an hour to do the first side and 15 minutes to do the next side as by then I knew what I was doing.
I got the new ones from ebay, listed as Febi Bilstein 32045 and 32046 for about £50 each which is less than half the main dealer price. They turned out to be identical to the original and once I opened the packaging I found they were labelled Stabilus just like the originals. You might want to also buy some spare expanding plastic trim rivets...
