Hi - new to this forum and have a couple of queries:
My 1994 Caetano Optimo 3 threw up a warning light yesterday that I've never seen before and neither has my service agent. Here's a rough idea of what it looks like:

Leaving aside the possibility of a spacecraft landing ahead, does anyone have an idea of what it could be? It went off shortly afterwards, but I'm now paranoid about what might be about to blow up/fall off.
I'm also having trouble with a leaking diff on the back axle. For some reason, probably cost-cutting, the rear plate was welded on, not bolted. Because it's not load-bearing, it's thinner metal than the rest of the diff. Several tiny pinholes of rust action are now gently letting out oil - about a dessert-spoon in 20 miles. Enough to be a problem. I tried cleaning it up and plastering it with a 2-pack resin a couple of years ago, but that's flaking off now. Looks like another axle is needed - I've asked Caetano for any info on the unit, but got no reply. It would be useful to know if it's a standard axle as fitted to Mitsubishi Canter, Ford Cargo, or whatever.
Anyone had any experience of this and got suggestions? Thanks for any help.
