hi does anyone know why my 2003 tdi 130 has a little oil leak its coming from the intercooler its not coming down the intercooler pipe from the engine to the intercooler it seems to come from the where the intercooler joins the pipe on the tension clip, my mechanic says they all do it after so many miles and there is nothing to do to put it right without putting a new turbo on ?? is that right its not a big leak and they is no slits or cracks on the intercooler
