Hi rbo135, many many thanks for your feedback, yes done filters also, I also spent about a week searching online about what oil to use and so many comments with different prefrences mainly Mobil 1 or castrol edge so in the end I just went on castrol website and they recormended castrol edge 0w30, when oil arrived I was a bit concerned because it said bmw LL04 (I expected it to say bmw LL01) so again looked online and found comments saying LL04 is also suitable for cars that require LL01, think I might just change it for castrol 0w40 do you think the new oil filter will be ok or should I change that also.
