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.
