Hi had the same problem with my mk1 earlier in the year.First check you have the 20amp fuse fitted then try jump leads, if it still clicks you need a new starter motor.I tried all this but the only way it would start was by pushing it. I had a new starter fitted at Millers in High Wycombe and would recommend them highly for there advice a good quick and reasonable priced job. Ring 01494 448158 and talk to Ann
