UPDATE on URGENT SERVICE mode

[Ncdan]

  My 2015 1400 tourer started throwing the dreaded URGERT SERVICE WARNING and going into the limp mode, at around 3000 miles. Beetle helped me do a reset and calibration twice and Pete has schooled me as to what is actually causing the PO155 code ( TPS/demand sensor) to activate. All the research I can come up with indicates there is no rhyme or reason that this thing keeps randomly tripping on then resetting, sometimes 2-3 times a day then may go a week and be fine. Yes, a very discouraging and frustrating ordeal to have to deal with, especially with a practically new bike. I decided today to just take the CRITTER to the dealership for advise, assistance, help or what the hell ever, they could offer, piss on the money aspect!!
A fairly local Indian dealer has just acquired MG and the service manager admitted it's already turned into a Royal PITA!! Can't get the company to ship parts, can't get calls returned from the technical support, new bikes shipped with parts missing, broken or in one case the wrong color bags on a 2017 tourer from the crate and the bike is still sitting on the floor with black bags on a totally red bike near a year later and still don't have the right bags. I'll give 10 to 1 odds that MG won't stay in the dealership ONE YEAR!!
Maybe good news's is they seem to be a great bunch of guys and old school attitudes and took all my information and said they would attempt to help me fix the issue. Said if they could ever get the rep to call them back they would see if MG could do anything since the bike only has 4K miles. They said it could take as long as a month or longer to get the part and that although they could get the sensor in 3 Days from Other sources, that MG woukd not assist in any way unless the part was bought and shipped from Italy.
Personally, I think maybe the Italians may ought to stick to making PIZZAS!!!

I have had this too.  Started about 5k miles.  First time really worried me as I was on a rally.  But it ran, just a little lumpy at idle and insufficient revs could see it stall.  Above idle, I did not notice any power problems.  After about 15 min., it goes out and back to normal.  It seems that dampness may have something to do with it and possibly sitting unused.  Yesterday was my first ride since the following Sunday and it started in that mode.  As usual, in about 15 min, it went out.  I am still barely in warranty and will try to get some joy on it.  I wonder if it is battery related as in if you don't have a really fresh battery, a slight lowering of the voltage combined with damp and sitting unused can trigger it.  Questions?

Blu, it's not weather related or any other reasonable explanation. I've have narrowed it down to a piss poor quality sensor that needs to be replaced. Like I explained in the post I have reset and recalibrated the POJ twice. Just some more of Moto Guzzi factory junk! If you are still under warranty, please, take yours to the dealer and let them analyze the issue because mine just keeps getting worse. The issue is not that it's not that bad after a while, the issue it's a D@€£ 20,000 Dollar almost new motorcycle and should not be broken after just a few thousand miles! We've come to the point that we are making excuses for nothing short of damn junk parts on these things. Sorry for ranting but I've about had a gut full of this type of crap from this manufacturer😡

I'm sorry to hear man.

I don't know if you remember Charlie (Avocatto). He went through a string of MVs, Ducatis, and Guzzis ending up with a first year Cali 1400 (all from FBF).

He did the Cali home and a day or so later came over to my place to go for a ride with Jay and I. We didn't get 5-10 miles from my house when his demand sensor (less than 100 miles on the bike) gave up the ghost.

The old man (Eraldo) came himself to pickup or maybe it was to drop it off after it was fixed. I guess that's the kind of customer service spending $100k on bikes over a ~ten year period used to get you with Ferracci.

I only spent like $20k in 3 years so he basically pissed on me when I BROUGHT my bike in and asked for help.

Anyway, good luck, hope they take care of it.

Thanks Kev, at least I own 75% of the 07 Softail deluxe in my sons basement next door. I may end up Road King shopping if this turns into a PITA bike. I'm getting frustrated with having to explain to my Harley buddies why a new motorcycle is having issues that there does not seem to be a reasonable diagnosis for, let alone a guaranteed fix after hundreds of dollars are spent for a sensor that may or may not fix the issue. I'm getting weary of trying to defend Moto Guzzis blatant half ass manufacturing flaws, same thing happens to the dealers who attempt to sale them to the motorcycle public. Sorry for the rant :(

Hey Danny, Cadre Cycle have the demand centres for under $400 if you can't get any love from Guzzi and decide to go DIY.

Thanks Mark, that's good to know and probably what I'll do. It woukd be good to be able to be 100% sure that will be the fix.

 Dan, Make sure there is no tugging on the throttle cables when handle bars  are turned  from stop to stop.  Mine did the same thing when I added bar risers and adjusted  the bars back. When bars were turned hard to the left it would tug ever so slightly on one of the throttle cables to the demand sensor and throw the code. I hope it's something that simple in your case. I have only heard of one of those sensors going bad thus far.  I've also read one case where the two metal, cable guide tubes locknuts going into the sensor had loosened and caused the problem. Have to pull the tank to check that one.

From the shop manual, Should be an easy diagnostic.

White rear connector throttle grip position (tracks C-D) P0155
� inconsistent signal
Error cause
� Two illogical voltage signals have been detected at PIN 23 and 11 of the ENGINE connector
(tracks A-B)
Troubleshooting
� Check the parameters of the white rear connector Throttle Grip Position Sensor - tracks C
and D: if one of the two values clearly deviates from 600-1400 mV, it means that this potentiometer
is defective. Check the throttle grip sensor connector and the control unit
connector: if not OK, restore. If OK, check that cable resistance between the throttle grip
sensor connector and the control unit is a few tenths of Ohm: if this is not the case, restore
wiring. If the value is correct, replace the complete throttle grip sensor

Thanks Lucian for the time you took to foreword this information, I will definitely try and get it to someone who can understand the content as much of it was over my head. This  will add to my option list greatly, if nothing else I can turn it over to the mechanic at the dealer who is going to attempt to help me with the issue. Sure wish you lived close to NC! I can check the cables and some of the list. I thought the ride by wire feature eliminated the cables?

Didn't you believe me when I told you there were cables from the throttle handle to the demand centre?   

[Kev m]

Dan,

Throttle by wire systems just mean that in the end the throttle doesn't have a direct mechanical connection and complete control over the throttle butterfly.

But there are some that, for whatever reason, still use a cable to go some distance between the actual throttle and the demand sensor/throttle sensor (or whatever electrical component sends the signal that the electrical throttle servo uses to determine throttle position).

Sounds like Guzzi used one of those.

Thanks Kev, I figured it may be guzzied in some way. If I had an issue it would just have to be something with at least 10 possible causes:(

Well no one climbs Everest in one day, or runs a marathon in one hour. You go step by step.

When troubleshooting you do the same.

* Check the cables for binding or looseness
* Check the connectors for loose or corroded terminals.
* Check the harness for opens or shorts.
* Only THEN do you suspect the sensor or ECM.

Lol my friend, I would  believe you if you told me the world was flat and I wouldn't  have to cross an ocean in a plane to come visit you however my little brain can only comprehend so much data at one time  before overloading. Remember my GB storage capacity is not as much as you and Lisa's are😉

[Ncdan]

All you guys that responded  to my rant and offered sensible knowledgeable information and techniques to fix the problem, made what felt like a great big issue, to look like just a small thing, now. Boy do I feel kind of out of line for the guzzi bashing. Allow me to apologize for that and I am reminded, again, to just trust your bike, company and you buddies that are willing to give of their time and knowledge to help us less knowledgeable. I now have a very clear plan now how  to fix this totally fixable issue. I'll keep y'all posted as to tbe problem identity and the fix.
You know, sometimes a piece of crow pie is good for the soul:)

[Markcarovilli]

Well you aren�t the first or will be the last - but it is understandable how you feel, and good to hear you are with a plan.....

[lucian]

Dan,  I sent you a PM with some info.  Look forward to hearing how you make out.  dave

Isn't an Italian bike the same as an Italian girlfriend?  You have to expect some pain.
