Hello everyone. I have "Warning H20 sensor" coming up on my dash and the engine temp gauge seems to be unreliable, reading very high or very low, regardless of the engine temp!

My Veloce is 2 months old. Has anyone else experienced this and is there an easy fix? I'm hoping this is not the start of many problems!!

Thanks.

Ive not had that come up, when mine had its first service, the dealer noticed a sensor playing up but not enough to register on the dash?
There is a new map which the dealer couldn't install at the time of service so I returned a week later to get it installed, smoothed it out so worth checking, scroll through your dash and see what software version you have installed, mine is 1.03 I think, I'll confirm that later.
I have been to get both rear indicators replaced, although the full rear arm had to be replaced due to screws being made from the finest Italian cheese and the tech being unable to get the indicators off so the whole arm was replaced.
All 4 indicators had condensation in them from about 150 miles but the front 2 cleared the back ones became worse, and the rear left stopped working, photo 1 was taken on the 15th the second was taken 1 week later.

Hope it's an easy fix for you mate.

Maybe the O2 sensor is malfunctioning and needs to be replaced?? Just a thought. Anyway, your dealer should be called. This is a warranty situation is it not?

What about coolant level? Have you checked it?

Are any of you paying attention???????

the H20 sensor is acting up and the ECU put an error on the dash .......the sensor is

bad.......

its not the 02 sensor or the coolant level!!!!

there is probably a test value in the manual.....

it will require;

a heat source

water

a thermometer

and an Ohm meter

:naughty::naughty:

Could be the wiring, the connexions, or the sensor itself.

On the Trepistoni
one is stuck at the bottom of the radiator
Part #25

The other on the cylinderhead
Part #10
http://shop.startwintrading.com/en/products/rivale/parts-3/engine-electric-system-11

They are relatively easy to remove or test.
Both got the same part number.

Took ages and lot's of obfuscation for MV to change mine.

Definitively solved the lukewarm engine start problem also :)

Usual suspects

Prolly

But the H20 sensor has a little rubber sleeve
with a kink in it to send the wires on their merry way

UP.

Suppose it's fitted pointing down or sideways and send the wires rubbing against the radiator.

2 months are plenty enough



Had the same problem with my F3, its the h2o sensor on the cylinder head
Yup :) the bottom sensor sends a different error MSG.
IIRC

Had the same problem on my B4 y14 after about 700 km. It took the dealer 3months to accept it was the sensor and it needed to be replaced on the warranty.
When it was claimed MV sent a new sensor and everything is fine so far.

I hate dealers who act like they're paying for warranty claims out of their kids piggybank. I mean come on....
