Hi…Castrol edge 5w-30 LL titanium 

prior to this it was serviced by Audi do whatever they put in was used

Thanks Stevey

it was a bit worrying because the previous cold winters there was no noise at all   …maybe wear and tear. 

thanks again

That’s correct 

only below 4 degrees on start up …all summer no noise 

John 

Thank you Chicco

my knocking noise is from cold start up ..quite loud and only happens when it 4 degrees or below.after the initial warm up it’s fine all day  till the next cold morning 

kind regards
