this does depend on if it is a 'new' forge ibiza tip that's been fitted & taken off - or if the person fitted a golf TIP to their ibiza?

it's not martyn's one on ebay is it?
 
if u are on about the one martyn is selling, i didnt think it would fit as the hoses are slightly different. Even the engine code makes a difference, mine being an AUQ martyn's wouldnt fit (so i'm told)
