The light with the exclamation mark - I had a Mk1 Focus for eight years up til 2 years ago and don't recall any such light, other than the brake fluid/handbrake warning light. Are you sure it's not that?
I'm very sure it's not that. The one you're on about is red, and on the right side of the dials.
The warning light that came up on mine was yellow and on the left, right above the 'check engine' warning light.
There is a a powertrain light on fords yellow light on left side of cluster u will need fault codes checked
I'm quite convinced it's this.
