Fiat grande 1.9 punto wont start. No glow plug symbol showing on dash ?

My fiat won't start.
I went through a puddle and now a lock and car light is showing in amber on my dash. The car wont start when the key is turned. The starter motor won't turn. The glow plug symbol is not lighting up on the dash either and I had I had a message to say to check power steering.

The battery seems fine. Can't bump due to a broken wrist.
Just hadbut back from the garage too.

Two nights ago the car went into limp mode and once we took it to the garage it was perfect. They fixed my disk brakes now this has happened
