Welcome, first post.

The display probably needs replaced. Most you could do is try a hard reset of the display, either by the dealer or with the AlfaOBD app.

 

Thanks for the reply. Uugghh - the cost of replacing the display!! . I disconnected battery but no luck.
will have to try the dealer...

 

I'd say its toast

 

You could just ignore it. Does it still fully displays everything?

 

Yes all else ok. Just not happy with line in the display...will get quote to replace..

 

It's probably a broken trace on the display circuitry. Not fixable. Once you find out how much it is to replace the display the green line probably won't bother you so much.

 

Thank you. Will wear shades when driving😂😂
