Bad spark plug....?
In some Italian (Fiat, Alfa) cars U1600 is code for bad sparkplug. Combined to injector fault makes sense.

I found this on a Fiat owners forum, but I don't know how it translates with the Piaggio ecu....

U1600- Electronic key-immobiliser system fault.

I was also getting this fault code occasionally... dealer said its to do with the plastic bit which sits around the ignition barrel and picks up the signal from the key, used to de-activate the immobilizer.

Its not a definite fault but a sign that this plastic ring shaped component isnt always recognising the key.
