2016 Stelvio shut off at hwy speed?

[GuzziGoneWild]

This weekend my 2016 Stelvio NTX just shut off at 100km. Red triangle lit up on dash and SERVICE across the lower section of the display. Lucky I wasn't on a busy section of road and was able to pull to the shoulder and coasted to a stop. After getting off the bike and walking around the to see if anything important had fallen off I thumbed the starter and it fired right up. It was raining at the time but not pouring, I've ridden in much worse on other bikes and never had anything like this happen.

Any ideas ???

Check your battery connections and earth strap mount for starters.

My battery is the first picture with they pretty blue fuzz.

[GuzziGoneWild]

I had read about that on the ADVrider forum but forgot about it. I will go and have a look at the battery right now.

 Thanks guys

Also, very soon take care of the internal wiring issue with the stock aux lights.  Many posts on here about that.  The wires will short out and kill your motor by stopping the charging of your battery.

I'm aware many have fused those lights. As an aside, I simply wrapped 3M fiberglass insulating tape around the leads coming off the bulb, which is actually the source of the trouble. I put two wraps of tape on the wires and preped a second pair of bulbs in case one burns out. I have checked those wires for wear, (the fiberglass tape), from time to time and all has been well.

edit: GGW, the fact that your bike restarted means this had nothing to do with your issue that day. However, you should perform this preventive measure before it bites you.

Your stall-out could be due to many things. It's probably a quirk caused by a bad connection someplace. May be good to pull up your diagnostic codes on your instrument display and see what is indicated there.

Check the ECU and coil connections.  Could be a bad coil too. A coil can function properly until hot and then short out.  You need to find the issue because, when you least expect or want it, the problem will likely reappear.


By the way- on those aux lamps, you can really get a phenomenally greater amount of light out of several aftermarket lamps.

let the dealer solve it

Thanks for all the input. I checked the battery, No corrosion and all connections tight. Aux light issue has already been fixed( High temp RTV coating on the Bulb leads and the orange loom) Aftermarket  100w bulbs installed . That was done at 1000 km and no issues since. Check codes and nothing showing up . I was thinking of coating the ECM connection with WD40 or a similar water displacement product . After I restarted it I drove for another 45-60 min in heavier rain in hwy traffic with lots of road spray. If it had been wet connection I would thought it would have happened again?
It was the long weekend here so the dealer was closed but they will be getting a call today.

It can happen.  I was riding at highway speed in Hungary a few years back when my Stelvio shut down.  Rain the previous day got into the fwd fuse box.  I also was shut down in new Mexico due to rain in the ecu.  And, then again in Texas.  I guess a Stelvio is not waterproof.

(reporting from Barcelona where it isn't raining)

[JeffOlson]

OP, I hope you get this sorted out soon.

I would be sorely put out if my Norge were to shut down because of rain. I don't need a submersible bike, but I do need one that can handle inclement weather, including a lot of rain.

:1:
And an Adventure Bike no less. Paul D suggested letting the dealer sort it out. Spot on, it's a new bike. Last thing you want is not finding the problem and then it becoming a real pita at your expense.

 Was thinking the problem might be similar Deke .

It's not a common thing on the Stelvio.

I've had mine in water up near the valve covers and never had any issues. And that was before the technical update of the rubber boot they put on the ECU. I would suspect a crappy ground somewhere.

[Kiwi_Roy]

Any ideas ???

What causes the red triangle and "Service", doesn't the manual tell you?
What's the point of a manual unless it describes what it means?

My thoughts is it might be a normally open contact that's leaking across with moisture like the oil pressure switch for example. You could simulate them one at a time with the engine running by shorting the wire to chassis to reproduce the engine cutting out.
It's surprising how much current can leak to ground with a dirty wet connection and the computer inputs are likely many times more sensitive than idiot lights (higher resistance)

I've tried like hell to get that rubber boot. How did you obtain it?

I had the dealer scan it yesterday and they came back with left and right coil code, they admit that's a very vague code but they don't have a solution. They have no fix for it and say it was likely the rain that caused it. WTF. Not impressed when the shop foreman says its a Guzzi thing and its common to get the odd random code. But holy crap, a bike just shutting down is dangerous as hell. This is obviously frustrating especially because its a new bike and I actually like the Stelvio better than any bike I've owned.

If it happens again I will be taking this issue up the ladder to the owners of the dealership.

I've never heard such a bunch of dunderheaded bullshit in my life!

Yes, sometimes issues like this can be vexing, Michael and I had a Breva 1100 in last month, it was throwing up a coil code and running on one, but it was intermittent. We played around back probing the entire loom and substituted every damn component and no joy. We thought we'd fixed it but it came back and bit us on the bum! Eventually I bit the bullet and swapped out the loom. Problem gone but there was nothing *Detectable* wrong with the original loom! ARRRGH!

In the end jobs like that always end up costing you money but that's the way it is sometimes so you budget it into shop time.

[beetle]

Odd random code my narrow white arse! Sounds like they're just dumbarses blaming the bike for their lack of concern. Yes, it probably was the rain, but where did the water get in? I know chasing ghosts is a pain, but did they bother to check the relevant connections?

What was the error code?

[leafman60]

A coil problem was one of my suspicions. Having both coils show a fault is weird. You may have a weak coil. However, I can't fathom why both coils would be a problem unless its wiring to or from both coils having an issue.

Do you know if the dealer checked all the connections to the coils as well as the connection of the plug wires to the coils?

Who sold you the bike?

When service Dept's say things like that is when I walk over the to GM of sales or higher and ask them right there if that is what they are selling. A short meeting of the minds usually happens right after.

Never happened with a bike purchase but with cars...

It's a factory update (recall). The dealer should provide and install it gratis, along with your new center stand.

[GuzziGoneWild]

So a short polite call to my salesman this morning explaining my obvious frustration and disappointment. With in 15 min a return call telling me they had the fix, NGK SB05FP spark plug boots and IRIDIUM CR8EIX plugs. I could bring it in but I opted to take the parts and install them when I do my Valve adjust and fluid changes this weekend.

here is the link they used to find the fix
https://www.motointernational.com/blog/news-and-events/post/spark-plug-cap-update-for-guzzi-8v-models

will let you guys know how if it cures the problem.

[JeffOlson]

I had a similar problem with my first Norge (though I never saw the red triangle of death). Pete Roper diagnosed the problem from half way round the world!

Piaggio uses rubbish spark plug caps that are easily damaged... Best to replace them from the get-go.

[pete roper]

The plug caps are fine as long as they aren't abused. The problem is that originally we were told that we should buy a specific boot removal tool which cost an arm and a leg so nobody bothered. The problem is that most owners and a host of shops don't know the 'Trick' to getting the boots off which is to pry them up from the bottom by inserting a long, thin screwdriver into the cooling tunnel just above the exhaust header and prying them up and off from underneath.

When Charlie J. took his second *New* 1200 in for its first service at a new dealership the after sales bloke from the importer was there and the mechanic asked him how to get the caps off and after-sales bloke says "Just grab 'em with a pair of needle nose pliers and pry 'em off!" Luckily Charlie was present and was able to jump in and stop them before they buggered his caps!

If they do get damaged though SB05E's work fine or SB05F's, the E or F suffix simply denotes the type of upper electrode fitting is used. For some reason we can't get F's in Oz

Oh, and both cylinders stopping firing at the same time would make me suspect phase sensor which should show up in the OBD.

I would remove fuel tank and look at wiring loom. Many on Stelvio's are smashed against the RH cap for timing chain tensioner.

Good

Check the tightness of the engine mount bolts while you're in there.

[GuzziGoneWild]

Wow thanks guys, I have a lot to look at before my trip in Mid June.

[THE BONE SHAKER]

I would also check the relays for the fuel injection as i had this exact same issue. For me it turned out that the hella relays which aren't fully sealed had corrosion within their contacts and therefore didn't work. I replaced all my relays with Narva sealed units and never had the issue again.
