Luckily the Panda doesn't monitor the reverse bulb on the can bus bulb warning system.
The 2011 eco does.
It just doesn't display it.
I was surprised when I interrogated the body computer it told me a number plate bulb was out.
no idea on the 100HP it does report a can bus error with some LEDs in the front fog lights. I wouldn't bet against it. Needs someone with a 100HP to try.
