Draining of the battery on my '03 1.4 tdi has become a total pain; have owned since new and it became a problem in '08 leading to AA assistance for the first of six times, the last being today! Five of those callouts have all been in Nov./Dec/Jan which suggests cold and damp effects of course, but no probs through last winter; car stands outside but not exposed. In '09 Ford Dealer who'd serviced since purchase had it back overnight to try to solve but no success. Going for months without a problem makes one forget and buying a 'booster' for those emergency occasions meant no great problems or urgency to ditch the thing. But now failed start 3wks ago and booster didn't do it.(AA sorted and replaced battery free as still under warranty and put in by previous AA chap!). Today AA again needed; again booster no use. So many permutations of where the problem is, means that no-one can pinpoint it. Is there a genius out there....coz, apart from bits of trim falling off it does what it says on the tin ...extremely well?!
