Urq ..Voice saying "Check Oil Level"

[Polarsilver]

1987 yr; Urq Wr .. Voice keeps saying "Check Oil Level "..( my sump oil level is correct).. so i look at isham research info to see advice is "0.3 oil pressure switch" .. so new sender arrived from Highland that has ( just as the original fitted sender ) the two contacts one is marked with symbol that i think is Gauge ? ..the other Contact is marked with an "X within a circle " .. this WR car has just the single gauge supply Wire= blue/ black .. asking for your advice what contact on the oil sender does the single wire fit .. as i need to keep Her behind the dashboard happy ?
Any other advice re this subject would be very welcome.

It should be connected to gauge on the sender

Can i ask your advice in how to overcome the Urq Wr Voice saying "Check Oil Level ".. this message & the amber dash warning light is constant On ..All systems look to be ok the engine starts & runs without any issues apparent .. My actions so far = Changed Engine Oil & Filters + Replaced Engine Oil Pressure Switch + fitted a Capillary test gauge & that shows on cold tick over the engine oil pressure is 5bar + using the VW1301 ohms tester the sliding scale Oil Temp Display on center dash is reading seemingly all ok. i can send using the VW1301 that display oil temp light up & down so that gauge is working. still this has no infulence on that Womans Voice .
I have lifted off the dash top cover & i cannot see where the blue / black wire from the oil pressure switch enters into that 35 pin multiplug on the back of dashboard..there are no apparent damaged & missing wires into that Multiplug .. so asking does that blue / black from the engine oil pressure switch change its colour before it goes into the Multiplug plug on the back of the dashboard?
just to note this WR Engine is only fitted with the "one" engine oil pressure switch as standard.
This Urq is a 1987 WR Green Dash & has been a family member for the past 20 years, nice car that has been resting in dry garage for the past 10 years, so now recommision is needed .. Please any advice would be welcome on how to Shut Up that Woman saying "Check Oil Level" = i have checked the oil level and it is all Ok.

I’m unsure how the oil level sensor is configured on the UR, but on my 10 years newer B5 it has a combined oil level/temp sender connected to the dash. That voice warning in your UR is not related to oil pressure, only oil level. Hope that helps.

le mans .. thanks as you made me think that on this Urq WR Engine..i cannot see any oil level sensor or find out how the Oil Level is sensed.. there is No evident way engine oil level is checked out by the electric system ..other than just the ( one ) engine oil pressure switch located on engine block.. So can i ask for any ideas to how the sump oil level is checked other than the manual dipstick as the Green digi Dash cannot do that.. or can it ?
When i look at published info about "Check Oil Level" that info refers me to the Oil Pressure Switch ( this component has now been changed & made no difference) .. so i go around in circles not getting to the solution... my only other thing to change would be the engine oil temp sender but that checks out to be Ohms Reading operational.. Advice from the S2 Forum would be very welcome.
This car is very original & has not been messed with other that several Theft Alarms of various makes have been fitted & later removed, currently the car has a Clifford Alarm that was fitted 20 years ago & is still working.. would that Clifford Alarm somehow have influence on "Check Oil Level " verbal warning ?
