'07 Breva 1100 Service Codes...... :(

[Suncoast]

I just got back from a 700 km trip and a few times when I went tostart up the Guzzi I had the red service triangle come up. I turned the key off and then on again and the service triangle didn't come back on, everything fired up and worked well. This happened 3 times. After I got home I entered into the service menu and have 2 codes showing M07 and M08, thats oil sensor and oil pressure.  Whats the difference between the 2??? My oil level is right up where it should be and I've never gotten the oil can light. What are the A codes verses the M codes? The bike is still under warranty but my shop is over 3 hours away, is it worth taking it to the shop or should I just possible replace the sending unit? I've heard some of the units are finicky and need replacing. Mine is a red '07 with a build date of March '07. Any advice is appreciated. Thanks

Suncoast,

Same thing happened to my Norge about 15,000 miles ago. I did nothing about it and it hasn't recurred since. I was told it was likely a sticky oil pressure sensor.

Had similar happen on my 1200 Sport.  Washed it and put it to bed, next morning red triangle and oil can warning about 3 miles into my commute.  Shut it down, coasted to the shoulder, restarted and has never happened since.  Guys on the Wildguzzi board assured me it was probably water in the sending unit showing a false reading.  Couple thousand miles later, all is good.

Thanks for putting my mind at ease, 8 months of owning it and I'm loving it more and more!!

A denotes codes that are related to something happening now.

M is a code in the memory, so it happened some time ago.

Oil pressure sensor is a pretty common deal, although there were some Norges that had oil pump failure I don't think I've read anything about that with the 1100s.

A-Active

M-Memorised as stated above.

Oil level has nothing to do with whether your bike engine is being lubricated.

Pressure sender is notoriously poor. Not only are they failure prone but they also don't like the wet.

the way they work is that there is a spring loaded thingy in the switch with a live wire attatched to it. When the engine isn't running the thingy makes contact with it's seat and the circuit is completed so the light comes on. When the engine is running oil pressure lifts the thingy off its seat breaking the circuit and the light goes out.

If the thingy sticks the light will remain on and the circuit will remain complete. Likewise if the outside of the switch gets wet it is possible for the current to short to earth making the light come on. with the crappy digitek dashboards you also have the fact that any continuing continuity in the circuit after the motor is running will trigger a warning as the dash knows the engine is running but it knows if there is no oil pressure then imminent damage will occur.

If you had a.) just washed the bike or b.) been riding in the rain it is almost certain the problem is just water in the switch. Remove the boot and disconnect the wire fron the switch and dry everything. Smear silastic aroubd the bottom of the boot, reconnect the wire and push the boot onto the switch. Then, finally, seal the top of the boot to the wire with another smear of silastic. If it recurrs? replace the switch along with the above proceedure.

 Thanks a lot for the tips, I'm not familiar with "silastic" is that what we refer to as silicone sealant?
