06 206 sw oil pressure gauge shoeing gauge fault

06 Peugeot 206 sw oil level gauge flashing oil warning and stop light on?

He I bought a 2006 Peugeot 206 sw 2 weeks ago on sunday I noticed the oil pressure gauge on the dash was displaying an oil level gauge fault ie: ------ six underscores flashing with no 'min' lit up. At the same time approx 5 secs after starting the engine the oil warning light comes on the car bleeps and the stop word illuminates and flashes.
Yesterday I changed the oil pressure switch(located on the oil filter base) but this hasn't fixed or changed the fault.
When checked with the dipstick the oil is at the top level and quite clean .... apparantly the car was serviced 3 weeks ago.

I'd really appreciate any info on what this could be and what I should try next only a week and a half old (to me) and I can't afford another.
Thanks in advance

You need to replace oil level sender. It's the one with the green plug top
