Hi All - this will be my first general post on here and I am hoping I can help some help/recommends and pointers

She is a 2011 Stelvio NTX and and my issue is not the fact that she'll need rollerizing - plenty of that discussion here and elsewhere but I am being driven half crazy with a dash issue  and just but just wondered if anyobe had a take on it.

Symptoms are that bike starts, ignition is fine - usual pump noise and dash board sweeps and checks.
Once riding after a random time can be 2 minutes - can be 20, the digital part of the dash corrupts, freezes, horizontal or vertical lines, sometime reversed mirror image , but always ends up going blank
but still backlit. Whole things resets itself on the restart - dash back on again and then rinse and repeat .

I felt sure this was dash board /instrument cluster issue (as everything else works and it resets each time ) and so have removed it and sent to autotronics in Leicester who fix dashes on guzzis - they say. 5 days and £160 later I have it back reinstalled it and road out to test. Exactly the same happened.

this week I took it back to autotronics that will relook at it but the likelyhood i feel is that they will say its fine, they bench tested it for 4 hrs last time.

Now I fear this is ECU dark magic  and Ive read plenty  sensors ,about water ingress , boots and grounding wires but Im honestly not sure Ive the ability to get in there - I did well getting the dash off!
(those winglets are staying off btw..)

Any pointers will be very much appreciated. Totally bitten by riding this great lump! the guzzi has something about it that my previous aprilias dont.

There has been a discussion on the dash internals before, including the problem you have, or at least something very similar.
The connections to the LCD display are usually some sort of conductive elastic, and these can cause problems. My guess is that vibration is causing it, something that won't show up on a static test bed.

Have you checked the throttle body balance recently? If that s out you get more vibration.

Just a thought, do we really need this sort of electronic complexity? Yes,I know I'm a dinosaur but problems with electronics do seem to be commonplace.

I hope the limb you are out on will bear our combined weight Dave P,  I think your question is well worth asking.
After all, those who wish to have electronic bells and whistles are surely capable of installing them, and as for the usual motorcycle electronics ----- not exactly aircraft standard are they ?
I am sufficiently prehistoric to think that whereas the customerĀ“s preference used to influence design, now advertising manipulates customer preference.
I suspect it is more profitable, though less reasonable, to make a motorcycle from a large number of small pieces, than a small number of large pieces. (I hope IĀ“m not being too technical here -- bear with me). Since each piece will need replacing, profit is a factor of multiplication.
In short, welcome to the machine.

Whilst we will all have our opinions about the complexity on modern bikes, it's of no help to someone with a problem.
It's like the reply to someone asking directions - If I were you I wouldn't start from here.

The question you need to ask Autotronics is whether they opened up the dash to test it or was it just a bench test where it was just plugged in and put through a programme of tests. Condensation is a well known problem on some of these dashboards which in turn causes all sorts of issues, however at 2011 I would expect the bike to be fitted with the later and better factory sealed unit. The downside to this is that the later dash`s are virtually impossible to take apart for repair.

I'm fairly sure the Dash is 'self-contained', i.e. the display is driven/generated internally, and not by the ECU.

Only way to 'prove' the issue would be to fit a known good Dash from another Bike.

Can you confirm, it 'resets' to working OK immediately after you switch off, and on again?

I asked for directions in Ireland in 1966 when on holiday and that's the answer I got.LOL

I agree with your view Ben.A friend of mine who has worked in the automotive industry for many years is fond of the expression "value-added"
I didn't really understand the term until he explained that the addition of cheaply produced components could then be sold at greatly increased prices as replacements for the failed originals. Very cynical you may think, but what the hell? Very profitable.

The dash is indeed self contained, it connects to the ECU but is not driven by it.

I can absolutely confirm that it resets and works everyime I switch off and on again.
Thanks for all responses - some great pointers there, Thanks chaps!

OK.
Next thing I'd try is to switch it on (don't start the Engine), and just leave it.
Check it every so often to see if the Display is playing up.
If it's OK after an hour, then it's likely a vibration issue.

Connect a Battery Tender/monitor if you have one, if you don't, you should really get one.
