Oxygen Sensor - Costly because of poor service

I'm really pissed off because of the lousy Guzzi service we get in the U.S. (maybe just Northern California). I took my 2009 Stelvio in for service many times for the stuttering engine, jerky motion. I reported the problem from day one. It should have been fixed under warranty. Now it's in a different shop and they say the problem is the O2 sensor and it requires a newer map. When the f#ck did a new map come out? And why couldn't Good Times Motorsports in Sacramento figure out my sensor was bad and a new map was available? They said they called Moto Guzzi and was told I had the latest map. Now it's going to cost me 2 hours of labor ($250) and $180 for the sensor, not to mention $539 for a 6200 mile tune-up. Over half of that should have been covered under warranty but some shops just don't have a clue. Bastards.
 
$539 for a 6k service! WOW! :shock:

I am so glad I can wrench my own stuff. Whew.

So sorry to hear you being treated like this.
 
Call these guys and hopefully Paul is still with them. http://www.automedicsupply.com/index.ph ... height=960 I've purchased Lambda sensors from them in the past when I needed them. Yes they have crossed referenced the correct sensor for the Guzzi but they don't list them on their site. The sensors are all the same, the difference is the connector for the bike's harness.
 
I wouldn't rule out the possibility of the wrong diagnosis again, despite going to the new and hopefully more reputable place. Is there a chance that the bike is simply still not set up right as far as TPS and throttle body sync go? Only asking because the first dealership you mentioned, for instance, tuned my Griso wrong twice until I talked about it with the head mechanic and pointed out the factory procedure. They also replaced near entire oil delivery system to the heads but the real issue of the leak on my right head cylinder was not fixed and turned out later to be one of the o-rings at the spark plug tube, something I'd researched prior and asked them to check out. Oh, and they did want $600 for the first service... I wanted to have them do it on a principle, having purchased the new bike from them and all, but at that price I just had to laugh. Glad I didn't let them have the bike a second longer, in retrospect.

Any error codes on the dash, under diagnosis menu?

If you ever get to Oakland, I can at least help you check the basic set-up, if you like. I have all the necessary tools and software to reset the TPS.
 
Try £900.88 (GBP) $1400 near as damn it...

Service, map update, steering haed bearings, rear pads, O2 sensor and an injector. 2009 Stelvio, 16k miles. :eek: :S

Its comforting to know it doesn't matter where u are in the world bad service , overcharging and lack of knowledge abound in the motorcycle trade. Got the name of a man here who works from home and is supposed to be good, know more service centers if i can help it , best of luck to you all.
 
I would be skeptical of the O2 sensor diagnosis as well. It is a common fault code when something else is wrong, since the reading from the sensor may not be returning the value the ECU expects due to whatever is wrong. It could be the sensor but they don't fail often, especially on low mileage/age bikes. I would be curious how they came to that diagnosis.
There are good mechanics out there, but here are more that aren't. That is not exclusive to Guzzi. My local dealer is okay, but I have one a hour and a half away that is better. I can't imagine them charging me to update the map, especially if the bike was in there for a service.
And that is a big chunk of change for a service. They actually say they spend 4 hours on the bike for the service alone? I would have to see that to believe it.

Forgot to mention, around here it is usually about $80 an hour. $125 an hour seems a bit steep.
 
I misfire due to a bad spark plug cap may even look like a bad O2 sensor.
And as far as I know, the latest map for a 2009 Stelvio came out in mid 2009.
 
Take out the ECU send it to Todd, get a reflash and remove the O2 sensor. Bike will run great and you'll have no regrets.
My 2010 ran like crap - I was ready to get rid of it, thanks to Todd - it was inexpensive- great fix and bike runs the way it should from the factory!
 
I went back and forth with the dealer and Piaggio. Both of them first told me that the problem was completely my responsibility - even though I had complained numerous times while my Stelvio was still under warranty. Todd, thanks for the suggestion to call Piaggio. I did not give up and called a few times. I discussed it with Thierry (pronounce Terry) who is the Service Manager in NYC. It took a couple days but Piaggio and the MG dealership in Elk Grove finally saw my point and told me they will accept the cost for the O2 sensor (part and installation) and the new fuel map. So I'm happy I don't have to pay the additional $400 (approx.). It'll take a couple more days and HOPEFULLY finally have a bike that doesn't ride like a Bronco and make my hands and arms numb.

- makarushka - thanks for the offer. I did not want to pay that much for a tune-up. I can change the plugs and fluids but have no equipment to check/diagnose anything.

- Wayne & GuzziMoto - thanks for adding your input.

- cmsmolka - right on! If I still have the jerking, rough ride, I'm sending the ECU to Todd!

Thanks All. More to follow.
