This one's been done to death...but bear with me...
Recently got myself an Mk7.5 MY17 R with ~7000 miles. First drive on country roads at the weekend revealed a harsh "knocking" sound from what sounds like the front upper suspension.
Sounds just like a knocking top strut mounting or classic ball joint knock. It is not noticeable at all at low speeds <20mph or when going over the much-discussed speed bumps, which is normally reported as a "creak". I've got a distinctive "knock" which is pretty much present with every bump in the road at speeds 40-60mph - very annoying and clearly something's not right.
I've since had the car on the ramp and the only discernible play (loaded and unloaded) is in the nearside front hub bearing (which I think is likely to be unrelated). Everything else is solid. I note the reported solution of replacing or lubricating the control arm bushings...While not totally discounting this as a solution, to me it doesn't fit with harsh knocking I'm getting from what I'm pretty sure is the top mounting/s. I suppose my questions is, can anyone confirm if the published solution of control arm greasing has remedied fault in a case such as mine (i.e. for knocking, not creaking)?
And before someone suggests taking to the dealer etc,...the boys in those workshops struggle setting engine oil level...so, not happening.
A bit of further background - my first issue with the car was noise from brakes when coming to stop from any speed. Found the front pads to be completely dry with no lubricant between pads/carrier. Removed/cleaned/lubed front pads sorted the brake noise...making me think perhaps top bearing is totally dry...still shouldn't really knock though. Lubricating top bearings will be a worthwhile first port of call though....as well as checking front suspension/subframe etc for tightness (visually all looks good).
