Mine went a few weeks ago, replaced with an £18.99 ebay repair kit, failed in less than 24 hrs, but I'm not totally sure I installed it correctly.
Bought a Meyle replacement OEM rail kit inc cables and regulator (whole thing is pre-built AND loaded correctly). I can't tell the difference in quality between the original and the new one. Very very good quality. Paid just under £50 from allgermanparts delivered.
I was warned about buying cheap replacement originally and should have listened. Having spent nearly £3000 on my car in the last 6 months I should have just paid for a full replacement rather than try to save money......well, it is practically a new car now, ha ha!
Follow the guides on replacement and its pretty simple......I found I didn't have a T45 Torx-bit though that you will need if you don't have one as its bigger than most sets go up to. Oh and I recommend having a soft area to rest the whole upper of the door when removed onto, prepared for putting it down on.
Good luck!
