They're electronic, so unfortunately the "loose cable" issue that typically besets tachos on singles isn't going to be the fix! These dashes are hard to open up (and re-seal) and there are no internal spares available. Some circuit board -related electronic faults can be sorted by specialists, but that's about it.

I do think the dash is a bit of a weak spot on the Z. Vibration damping is poor and the quality isn't up to the mark. I am on my third dash! First was replaced under warranty due to water ingress/condensation (which came back on the replacement) and the second time was a couple of years back when the tacho needle fell off! Before this happened it did get erratic, but didn't notice any noise, but then I wouldn't with the DNA intake roar and aftermarket pipe! Ultimately, one day it breifly got stuck just over 5000 rpm and then subsequently fell off. I was lucky to find a used unit for �130. I know of at least two other Teneres where this has also happened.

See how it goes... I wonder if your needle will eventually go AWOL?
