Hi, I have just bought a Audi A3 1.8t 51 plate. Forgive me if this post is not the best as I am new to posting on forums, but read them quite a lot. Basically I am just posting to see if anyone has any experience in flushing these engines with fortes engine flush. I have read quite a lot on this but the post are from years and years ago. The ones I have read basically suggest if I am to do this I would have to drop the sump as soon as I drain the oil, clean it or replace it. Or otherwise I will just block the pick up of oil and starve the engine. Does anyone have any experience of dropping these sumps? Any advice on this would be appreciated whatever the input.
