As the Brevas come out of warranty, and the Norges will be soon,
the Einsteins in Mandello have finally decided to offer the fuel level sensor as a separate item,
as opposed to a complete pump assembly.
I know we have replaced a couple pumps due to level sensor failure.
Pure genius.

My guage was not reading full for a few thorusand miles, then the filter fell apart from the plastic section expanding. When the dealer replaced with an all metal filter and better hoses, the guage started working correctly again.

I'm not sure I understand the intent of the bulletin - am I just dumb or is it my lack of understanding the Italian tech spoeak???

Is it saying

1) That in future they will just replace the sender unit if one is found to be dud, rather than the whole pump assembly which includes the sender by default. Presumably this would be because they have realised that they really are a crap design and it was costing a motsa to replace the whole unit but that was all they had, and now they have sourced a heap of individual sender units to keep the bean counters happy because they know that they are going to continue to fail.

or

2) That they now have admitted that the sender units are a crap design and have a newly designed one that will give more accurate readings and be more reliable.

Hopefully both Mike.

You have to admit it makes far more sense to just replace the level sender rather than the whole caboodle. Not as if it will take any longer to do either.

Looking at it from the perspective of a Norge owner whose bike will be out of warranty in 7 months and who has not had a problem so far. I would certainly would rather pay for the sending unit rather then the whole assembly. When will they ever learn (not just Piaggio) that bean counting doesn't replace a good dose of common sense thrown in.

My fuel pump crapped out at 1000 miles, another installed from a demo bike by the dealer, the pump worked, the gauge did not, then another pump installed from a new bike sitting on the floor and all has been fine since. I can't believe it has taken this long to figure out that the gauge sensor can be replaced. Go figure.

[abbienormal]

Do they just quit reading anything or is it a partial failure. I called my dealer a while back to report my gauge would only go to 7/8 tank and not full. I said I could live with it but if it was a harbinger of future trouble I would like to replace it.

hi to all!!
the sensor fuel has been replaced once me in guarantee (breva 1100); after 2 years you/he/she has started again to be very volatile, then I have gotten off him and ritarato the inside rubber bands, so that give the values (ohm) correct.
full reservoir = 10 - 20 ohms
empty reservoir = 260 - 300 ohms

now is ok!!

I don't know if this works for every one, but it certainly does for me.

I have a 2006 B11 (bought new). Under warranty I had the fuel sensor changed because it started reading only upto the half way mark.

About 6 months ago, the problem resurfaced.

What I discovered is, I let it run for about 20-30kms with the low fuel warning light on. Since I've started doing this, it's being reading correctly even if I don't do it every tank.

cheers
