Vacuum advance unit.
Water pump (leak revealed on cambelt change).
Poor MPG.
Heater matrix.
Battery.
Failed central locking (caused by a cowboy alarm fitter).
At first I had poor MPG (30) so I called out a mobile tune-up specialist who diagnosed that the Vac advance unit had failed. After replacement, together with new leads and a full service and oil flush it now runs excellent returning 40 MPG on my daily commute to work.
Roll on Summer!
I wish mine did even 30 mpg.
