Hi,

Went through manual for my R1200R (2011) and did not find any reference to alarm of low engine oil pressure. There is no indicator on the dash as well.
Applied to RSD and it is looks like pressure sensor is available , but only for service purpose...
Does anyone know how come this is possible? Never seen any engine before without this alarm. Also read manuals for R1200GS, RT, old R1200R- indicator is available on the dash..
looks like this feature is absent only on new R1200R

thanks,
Alexander

It's hard to believe that there is no oil pressure warning. The manual for my '07 indicates that that the symbol for an oil can appears as an oil warning. The manual text says:

Warning light for engine-oil pressure flashes.
The oil pressure in the lube-oil system is too low. Stop immediately and switch off the engine.

The warning icon looks like this, and should appear before the engine is running when you turn the ignition on:

Same here for my 2012-build R. Amazing! On my last bike, 2011 GS, there was a very useful function in that one press of the <info> button (engine running) would momentarily show an <oil pressure OK> readout on the OC screen. But it, too, is absent from this bike.

Frankly, I'd rather have an oil-pressure readout than a tyre pressure readout if it came down to a choice.

I wonder if Motorrad ever talks to their customers?

I downloaded a Riders Manual for the 2010-on R12R from a BMW corporate website located here: BMW Motorrad International

At page 26, there's a chart titled "Warnings, overview." Under the column header "Warning Light," I see the oil can symbol commonly used to indicate engine oil pressure; next to that symbol, the text says "Flashes" and "Insufficient Engine Oil Pressure (→ 28)."

On page 28, there is a discussion titled "Insufficient engine oil pressure," with the expected "turn it off at once if the light goes on while the motor is running" exhortation.

I acknowledge that I haven't actually had one of the later bikes or their physical Riders Manuals in my hands, but I would remain surprised if an oil pressure warning light were not present in these machines.

Oil Pressure Switch

Yes, I agree. I would prefer to have one if I could choose.
Haynes Manual states perhaps the oil pressure switch is used only for factory testing during production, and not part of the later 2012-2013s.
Roadster is a lower priced model, and bean counters have to make cost cuts somewhere. Omit fuel bars and temperature bars. Fuel strip instead of a float. No keyed helmet lock. No heated seat. Etc. Perhaps you could pay to retrofit one. ??? A front fender extender, cooler cover, and a GS skid pan my offer enough protection to guard the cooler and filter. Not to defend BMW's decision to omit it, but ABS is standard now.

i am not sure of price buildup for BMW in USA/Europe, but price of 1200R Classic in Russia is between hispec GS and ADV...
If the retrofit kit would be available, I would definetely pay for it, otherwise I will make signal lamp myself, the problem is where to place it on the dash and not to damage bike style..

looked at the bike today, pressure switch is available, there is wire connected ... strange ... everything is available apart from indicator on the dash.. does anyone has electric schematic for r1200r?

No schematic,

I do have the manual for a 2012 r1200r in RED! :001_tt2:

No where does it say oil pressure warning of any kind. No picture of an oil can in the manual or on the bike.

I bet the sensor is used to run the fuel pump. Its a safety thing If the engine quits, as in a wreck or what ever, the oil pressure goes to zero and the fuel pump shuts off. So, no oil pressure the bike quits anyhow. If it does its probably too late.

This is why you only hear the fuel pump for two to five seconds. It starts again when you are cranking. f

I DID notice the fuel and temp gauges are an OPTION with On board Computer. I did not choose this option, it was a package on the bike with ABS, ASC and heated grips. Standard or tall which ever you call it comfort seat I can ride all day on.

I'm still surprised, but I guess I can imagine an internal connection between the oil pressure switch and engine controller to turn things off if the pressure drops...sounds like the "no dipstick" recent BMW cars.

I just looked through the parts fiche on realoem.com for my '07, and I don't see an oil pressure sensor. I think there's one on the motor, as instrument cluster has an oil pressure warning light in the display which goes on when I turn the ignition on and off when the motor runs.

When I change the oil on my bike, I do it when its really hot. Pull the bike in the shop and pull the drain plug. This gets all the stuff suspended in the oil out.

Next I change the filter, add the new oil and start the bike. I can tell it picks up the oil because the filter gets hot once I start the bike.

The only gauge I have ...

Thanks to the original poster for bringing this to light.

pressure switch is located on left hand engine side, above oil gauge and below cylinder. there is one wire goes to it.

Yes, I see the switch on the bike. I just can't find it in the parts diagrams.

That is odd, I never even thought about the oil pressure warning.

Apparently and according to the mechanic at my dealership, they have one warning light for all engine failure functions including oil pressure.

I don't know if this is true, he couldn't show me anything in writing.

Ah, for my bike it's #3 here: RealOEM.com * BMW K27 R 1200 R 06 (0378,0398) Various switches/relay

The same switch is shown on the fiche for the Camhead bikes; the fiche doesn't show the switch's location.

this is easy to check- remove socket from switch and start engine, see what alarm will pop up. I am far away from my bike and cant check it, but may be someone here can? If not- i will try this is two weeks when i get back home.
