This "story" took another turn when i ordered a new 08 Civic type S GT 2.2 and his car does exactly the same. He has come from the old shape Type R and knows a bit about his cars. So annoying is this knock i now run around with half a tank of fuel, took it back to the dealer last week and they said it was AGAIN just the fuel - ITS NOT. I have half a tank in this morning and NO knock, no sloshing, NOWT. Now, I also ordered another 2.2 sport in
NHB for another driver and his car has NO noise's whatsoever.
