Hi everyone, I have splitting issue with the small hose that goes to from the charge pipe to under the N75 valve. it has splite 3 time recently, I went to audi today to buy it, but they say the sell the entire kit only for nearly £90 not good! does anyone know which size hose/tube I need to buy from ebay? they have 3mm to 10mm! not sure what is best, also what size clips for the boost hoeses as they keep moving about thanks.
