Can anybody out there help with a couple of small problems :- (1) Pictogram comes on when brake pedal depressed --bulbs are all working! and (2)when engine warmed up oil pressure warning light comes on. There no leaks & performance seems unaffected Thanks in anticipation

Common problem, caused by either slightly different quality of grounds between the two sides, or by a faulty relay. The bulb failure warning works by comparing the current flow between the two sides by passing the current through two coils would around the same relay core but in opposite directions. A slight imbalance and the relay clicks on.
Either live with it or try swapping out the relay. If swapping the relay doesn't fix it, you have to start looking at your ground connections at the back of the car.
Hmm, this could be more serious. Either you have a faulty oil pressure sensor, a wiring fault, or you really have low oil pressure. If it's the latter then your engine is in trouble and won't last long. Investigate now.
or, more cheaply, lamps of different wattage. Buy a couple of new matched lamps first.
