as above i have also suffered the above issue and many hours spent searching and researching this problem ..its finally cured... i replaced my fans with golf mk4 fans which are exactley the same as the cupra r fans, even the part numbers on fan frame are the same and the location for the electric after run pump is there.... so i hope ths helps everyone and its a lot cheaper than stealers took my 1.5 hrs to remove and replace...
