Hi, TD5 (2005) owner based in Botswana. Recent problem where it won't start. Doesn't appear electrical - dashboard lights up. Small click noise from engine bay but effectively appears to be immobilised. Think this may be where the issue stems from. Turn the key fob on/off multiple times or come back to it later and it starts up fine. Little immobiliser light is not flashing when unlocked. Any suggestions or ideas welcome or typical issues in this regard. Happening now with increasing regularity and worried it may give up altogether. Thanks.
