Got a forge diverter valve for the regular GTi for sale in the classifieds. Used for about 3000miles its in excellent nick and the perfect solution to you DV probs on both standard and remapped GTi's. The only reason I'm selling it is I kept it of my last GTi and doesn't fit the ED30. Think there about 120-130 quid all in new, I'm open to offers.
Cheers
Gary
