This rubber joiner split on my car but lucky enough I didn't get the fault code. Might have something to do with my tune. I tried to get the rubber joiner from Ford but you can't buy the joiner without the factory plastic pipe bend apparently. This was gonna cost $90 bucks which I thought was rediculous. I managed to get a joiner off ebay and fitted some better hose clamps, has been working a treat. Benny
