Oil pressure light comes on at Idle with hot oil!

Well that’s concerning.
So if the bike is key on, kill switch on, not running I’d assume the circuit would be active and also have continuity from a “working” switch causing the triangle/can (can I say trican?) to illuminate.

I’m theorizing that if the wire has a bad connection then it’ll act as though it has pressure but once grounding out (possible leaking switch?) it’ll act as low pressure.

The pressure sensor is a normally closed switch that provides a ground path for the oil pressure light. It opens with oil pressure. A poor connection would act as an open indicating pressure when you don't have any which will trip a fault code.
 
Both of my previous Stelvios had intermittend oil pressure switch issues, replacing them solved the problem. Just another MG issue that needs to be fixed. Good thing the bikes are fun to ride
 
Well what a miserable PITA that was.
Got the tank off, Airbox out, oil pressure sending unit out without removing the alternator, considered cutting the 21mm wrench so I could get a 1/12th turn on it.
Horrible job but not worth farming it out.
Oh and I also dropped the new sensor beside the hole it resides in and had a bad time getting it out. Used a magnet and needle nose. IMG_4601.webpIMG_4652.webp
 
Same problem as yesterday. After a ride at over 2000m altitude in the mountains on a hot day the oil warning light comes on. After the engine has cooled down, the warning light comes on again with the engine over 60°C. I'm going to change the sensor and hope I haven't done any damage on my way home
 
Even an analog sensor fo the oil pressure gauge can fail and give wrong information. Anyway this my sensor. Forcing an air pressure inside, it shows 100ohm, not 0.
Now I ordered an equivalent from Hella, and I'll update you.

Update
Rode around the ‘hood tonight for 45 minutes. Slow/fast/slow again etc so on and so forth.
No oil pressure light, no triangle of death, no tin man oil can.
So now I’ve replaced the upper and lower sump gaskets and the pressure sensor plus had the fuel tank off and Airbox out plus reassembly. Insert getting to know you song here:

Don’t say that…

Rear main seal replacement is serious major surgery.

Is this a main oil seal leak?

Welcome to the Forum, and congrats on the Stelvio. One of my all time favorites. Hope you'll add your info to the Registry here; https://www.guzzitech.com/forums/threads/stelvio-registry-pics-thread-add-your-bike.11540/ Per the paragraph in red above, ALWAYS try a search first. There are pages...

I think I know where I veered off course….
 
I don’t know as I cannot see what you’re trying to take a photo of.

My oil lamp issue finally solved with the M12 sensor replacing🤞. Bought an Hella 0.2-0.5bar on Amazon with 10€.
 
As usual, late to this party.

Also no longer have a Norge; Lordy, I miss that beast.

An early adopter -- a disease I've since (pretty much :wasntme:) cured, thanks to the Norge -- I had your oil-pressure madness and rear-main-seal issues, plus engine seizure from faulty oil pump, CARC self-destruct, and many more. Guzzi fixed the engine and CARC under warranty.

On my own, I finally fixed the OP issue as did you and countless others by replacing the connection ... and several new OP switches before I realized that the switches worked just fine, but the contact didn't. That led to all sorts of angst on the road. When I finally sold it last year for age issues -- mine, not the Norge's! ;) -- I had sorted out all of the maddening issues ... except that main seal leak.

I decided that it really didn't matter. Heck, I was more incontinent than it was. :giggle:

Seriously, and this may make the real wrenches and neatness nerds here groan, but on any sort of X/Y "value" assessment, the time and cost of such a fix seems, IMO, at least, to outweigh the benefits. So, unless it just drives you nuts, I'd view it as yet another endearing "feature." Besides, for former Volvo owners, it just seems natural. :rofl:

OK, I've thrown that cherry bomb into the pond; let's see what bobs to the top. ;)

P.S. @Captincvmn, you are just up the road; come visit the Moto Grappa at the top of Virginia sometime.

I’ve grown to really enjoy this bike. It’s an expensive thing to learn on mechanically but worth it. Paid $3k for it. I own a Land Rover Discovery so leaks are customary. My rear main was actually my transmission front seal as I had stuck the breather hose on a plastic knob on the Airbox that had no hole in it. Pressurizing the gearbox when hot. Undid that and problem went away. Checked fluid levels afterwards and they were acceptable.

I still have an engine oil drip after riding from the belt cover area which is concerning but leaves a spot 1” under bike after it’s done. If I just accept the fact that it’s not 100% sealed, maybe my life will be easier.

North Virginia eh? Sounds like a pleasant trip down 15 to 270 to 495. But that sounds like a horrible trip on a motorcycle. Maybe in spring after I’ve ridden more.
