As per the title, front OS bearing drone. I checked a few youtube videos & had a go at removing the old hub/bearing with the intention of fitting a new one, ordered from amazon at a reasonable £59.99.  

I got the back 2 bolts out & the front upper bolt only to find the lower front bolt was partially covered by the rather large CV joint which needs either pulling in towards the gearbox or the lower arm needs removing to allow the whole assembly to move away from the CV/ drive shaft. I could not do either, so after putting it back together it went to my local indy VAG mechanic Chris Umpleby who 2 or 3 hours later had it done. £60 per hour plus & a new wheel sensor @ £30 +VAT.

It's been a bit expensive recently but still a great car. 

It's satisfying to the job yourself but sometimes you need the big guns of a professional, whether they be impact wrenches or a lift.
