If oil is anywhere near full and the sensor triggers a code or warning, that's the test...it's bad.
Do you mean the signal wire give only analog voltage message to the control unit?
My A6QV8 had malfunction with oil temp gauge because of aftermarket oil level sensor, using VCDS it gave always 30*C temp and HIGH oil level.
OEM level sensor solved problem.

I'm told by my Audi SA there is an issue with the hood latch that affects the sensor. My latch is pretty tough to open, so I will follow-up with it.

I had oil level/temp sensor issues. Checked wiring diagram, ran extra ground, etc.
Then came across a post where someone warned to ONLY buy the OEM brand sensor (I had bought a well known German brand name, but NOT the (Meyle IIRC) OEM brand). Finally gave up, bought a new (OEM brand) sensor: worked correctly right away.

Hella is the OEM brand. Anything else and they sometimes work and sometimes do not.

Confirmed. Meyle (good solid brand) did NOT work. ONLY HELLA (OEM brand).

Very sorry to bump an old thread.
I've got the same problem with my Golf GTI since last winter after a woman hit me.
I've changed oil and sensor (with an used one) but the nagging OIL SENSOR WORKSHOP just stays on the display and annoys the crap out of me.
I've checked the hood latch, and found out the cable to the connector is missing, so I jumped the connector to simulate open hood, but that doesnt help.
Diagnostics show -60 degrees (celsius) on the oil temperature, so I figure that the sensor is faulty or somewhere around the wiring im having a short.

Any ideas how to inspect the wiring from that sensor?

For the record Meyle is not good or solid, it is questionable at best.. NEVER on any of my vehicles.

For anyone else struggling with their sensor. I bought a cheap one off ebay and it didn't work., despite having my car listed as compatible. Further correspondence revealed that it wasn't compatible so I sent it back for a refund.
Then bought a HAAS one from Euro Car Parts. I phoned them as they didn't have any listed as compatible with my car on their site. I gave him the part number from the OEM one and he gave me the stock number and I ordered it online with a discount code for £24.
Fitted and works just fine.
My car is a 2002 so I'm not about to spend £100 on a sensor if I don't have to.
