Thanks for the input gents. Once again this morning everything was working normally, so I tried the IPK test (no.2) and nothing happened. Tried it with engine off, engine running, etc. but nothing activates. Went through some of the other tests and some work, some don't (eg no.13, test the door 'gong', but nothing happens ??)
Am I missing something here, as when I go to IPK engine temp, it gives the reading virtually straight away
