Nemo Turn Signal Fault

Sounds familiar. I had a similar issue with my Nemo, especially the speedometer error. Did you check the flasher relay? Is the lens cracked? Even a small crack can let moisture in. Mine was a corroded connection in the wiring harness. Check for corrosion or damage to the wires.

Where exactly is that wiring harness located, and how bad was the corrosion? Was it easy to see, or did you have to look closely?

The harness runs along the inside of the wheel arch, behind the plastic liner. Remove the wheel and liner for access. My corrosion was advanced, like a green powder. Unless you're comfortable with electrical work and have the tools, a workshop is best. It'll save time and frustration.

Thanks for the advice. A workshop visit seems right. I'll post the fix and cost. Initial estimates are around 95€, which seems fair. Thanks again.
