Can anyone advise - changed the oil pressure switch and had service ond oil filter. Red light next to temp gauge appeared on dash - car not used and fast forward a few months now this Red oil filler light is on - oil level good, changed the oil pressure switch again - no change. Car ticks over fine, no overheating etc .....Car is a 2009 Eco 1.1

Disconnect the the connector
Measure the voltage from the wire to earth
Should be 5v

Get a mechanical oil pressure gauge and screw it in instead of the oil switch, if no reading then it
could be the pump it's drive or oil pickup, maybe a stuck pressure relief valve, if you get a reading
the wiring from the pressure switch is suspect

So the "High temperature" light is not a problem, it doesn't stay constantly on, does it? It should light up for check as soon as you start the engine and go off immediately.
Oil light on is worrying. You definitely shouldn't drive the car with it on. First find out what triggers it and fix it.
As @RalphM said, the best way to go at it is to have a pressure gauge put instead of the pressure switch and read the actual pressure. Normal oil pressure is 0.9 bar on idle (might be higher on cold oil) and 3.5 bar - 1.2 engine/4.2 bar - 1.4 engine with engine running 4000 RPM.
The pump might be faulty or it could be an electrical malfunction on the pressure switch line. Gotta find out which is it.
You can test the switch by having it out and connected to electrical wire. Turn the key on (without starting the engine) and the oil light should pop on. Apply pressure with a compressor on top of the switch. If it is working the light should go off. If light stays on, switch is bad.
What switch brand ddid you buy?
