Since pulling the MP3 out of storage for winter duty last week I have noticed now on several mornings that there is moisture on the inside of the instrument cluster lens. The bike sits outside in covered parking.

It is predominantly around the fuel gauge area.

When I let the bike sit in the sun the condensation eventually disappears but usually returns the following day.

I have checked the boot at the pigtail end of the main wiring harness where it connects to the back of the cluster. Looked OK.

I'm guessing maybe there is a seal between the lens and the cluster that has given up the ghost. Hopefully a entire cluster replacement is not necessary.

Anybody seen or have this happen and what was the fix?

Crossing fingers this is not a major operation or high dollar item. Otherwise, the MP3 will be at the end of the road under my care.

My bet one of the reset button seals is on its last legs, maybe put a bag of moisture grabbing beads on the cluster overnight to try to suck out as much moisture as possible, will not fix a seal but could help to see better the guage

Sadly this issue is not exclusive to the MP3, it's endemic throughout the Piaggio /Vespa range. My GTS suffers from it and it is garaged and rarely gets wet.

Here's a thread discussing the problem...

A quick update, and a potential fix

I tried a few of the silica gel packets as suggested above the buttons, central LCD area and inside the 2 dial rings. No difference whatsoever.

So I figured humidity must be getting in somewhere else. I removed the windscreen and the front end and discovered that the rubber boot where the vehicle harness enters the instrument panel has lost its elasticity and ability to seal. The best way to describe is a old sock that drops down to your ankles.

In my case, the boot offers zero resistance and easily slides away from the cluster.

So I removed the cluster and put it in the oven at 50C (+-120F) for about 30 minutes with the dials facing down (away from any heat source).

I did discover that the pins on the instrument cluster had a light white/grey ash coating. Not the dreaded green death, but something has definitely been making its way through the boot. I cleaned up the pins with a nylon brush and repeated for the mating connector on the harness side. I then sprayed Deoxit and applied dielectric silicone grease (as used on spark plug boots) to both the connector and the pins.

Reassembled everything, and slid the boot back onto the cluster. However, I used a zip tie at the harness end of the rubber boot to accomplish 2 things. 1) Force the boot onto the cluster under all conditions and 2) to keep any and all traces of contamination (dirt, muck, humidity, water) out.

Will keep an eye on it over the next week and report back if needed.

2 questions for the forum

1) The rubber boot does not seem to be available as a separate part, except with a complete new vehicle harness. If anybody has a part #, it would be greatly appreciated. Considering the expense of a new harness and the fact it requires a complete bike teardown, I'm trying the cheap solution first. Not willing to entertain such a big undertaking with winter knocking on the door.

2) How do you unpin the connector? It didn't seem to be the type that you can unpin, or I missed something obvious.

Is the boot this one circled and number 10 in picture, if so surely someone can track a similar one down




Maybe you could find something similar in this google search below

Just a quick followup.

It's been a couple of weeks since I applied a fix for the condensation issue and am happy to report that no more condensation has been seen since.

The bike has been sitting outside day and night and under a variety of weather conditions.
