I have a 2003 Turbo S Beetle that has a very slow antifreeze leak. I took out my air box and saw it drip down from the flange so I replaced the flange with an oem one. I put all new G-12 back into it and drove it and its still leaking. It appears to be coming from somewhere just under the flange. I figure it was spraying on the under side of the flange and then dripping down and it fooled me. It is running down the block somewhere under the flange (that connects to block) and running down the transmission. Its not bad but I don't like it. It seems to only do it when it's being driven. It will not leak when it's idling. Please give me some pointers? Thanks in advance!
