I've been having the same probs with my 16v recently. Below is a link to the thread about that, which includes a lot of useful info people came up with;

I've made good progress in sorting mine (I'm not going to say it's sorted yet, just in case...) by dismantling, cleaning and reassembling the earths on the earth stud under the battery tray.
