Flashing dashboard lights and clicking noises

[Pilote]

Hi, I have a 20vT Passat year 2000 been very properly behaved until recently - seems to take some turning over and the dashboard lights flash on and off and there is a clicking noise in the passenger door then it fires up - last night I started it up and into first gear and nothing engine running but foot to floor on accelerator and not a rev at all - left engine running for 20 mins and then decided to have a go in reverse, stalled it and on re-start had revs and got it home - its recently been on a diagnosic scan found nothing - and we had a towbar fitted - if anyone has had similar problems please give me any help the wife's terrified to drive it now in case it does the same again.
