Can only tell you for Clio 01 onwards but Kangoo should be same. Unless anyone knows better of course.
The stop light and handbrake light can be on if brake fluid is low.
Obviously the handbrake light will be on if handbrake is on but in that picture you can't tell.
The handbrake is on in other picture but engine not on.
The stop light usually comes on along with another light and not usually on it's own.
The stop lamp can be on along with
pressure lamp or battery lamp or handbrake lamp or faulty wiring to previously mentioned circuits.
Eg. fault in brake fluid level sensor or it's wiring.
Can also be linked to dash pod fault. Or possible fault in abs wiring.
There may be other reasons but you would need a techie for that.
Can't find anything relating to stop lamp and engine running problems and if the abs had a fault you would have thought the abs light would be on.
As Vel said, message them and see if they spin you some bull.
