S3 propshaft query

[ScottyP86]

Being a fairly new Audi owner, I’m hesitant to fire in and buy a replacement propshaft (used). Seeing plenty parts on eBay at fair prices but none with the exact same part no as mine 5q0521101bh. Do other similar parts also fit? For example a prop from an s3 saloon? Or would it have to be the exact same item number to fit correctly?

There are unbranded new parts for sale on eBay that are definitely compatible but I’m unsure how reliable they’d be in long term.

Mines is Audi s3 2016 petrol hatch 8v18vk

any advice would be greatly appreciated!

Welcome Scott and thanks for joining, 

Is it the propshaft joint which is showing wear?

If so, try Parts in Motion at Exeter. You are likely to get a good branded joint there, such as Febi. 
Perhaps you could let us know how you get on.

Kind regards,

Gareth.
