At the Indian GP Kobayashi is recorded as receiving the following:
Not sure what year but, for me, the relevant bit is about gaining an advantage and Rosberg so obviously did. Having had a scan through the rules the stewards can issue a warning if they think that is appropriate. This is the passage from the regs.

Kamui Kobayashi (Sauber) Leaving the track and gaining an advantage, driver was sufficiently ahead so no advantage gained, no further action
Not sure what year but, for me, the relevant bit is about gaining an advantage and Rosberg so obviously did. Having had a scan through the rules the stewards can issue a warning if they think that is appropriate. This is the passage from the regs.
6.1 "Incident" means any occurrence or series of occurrences involving one or more drivers, or any action by any driver, which is reported to the stewards by the race director (or noted by the stewards and subsequently investigated) which :
a) Necessitated the suspension of a race under Article 41.
b) Constituted a breach of these Sporting Regulations or the Code.
c) Caused a false start by one or more cars.
d) Caused a collision.
e) Forced a driver off the track.
f) Illegitimately prevented a legitimate overtaking manoeuvre by a driver.
g) Illegitimately impeded another driver during overtaking.
Unless it was completely clear that a driver was in breach of any of the above, any incidents involving more than one car will normally be investigated after the race.
16.2 a) It shall be at the discretion of the stewards to decide, upon a report or a request by the race director, if a driver or drivers involved in an incident shall be penalised.
b) If an incident is under investigation by the stewards a message informing all teams which driver or drivers are involved will be displayed on the official messaging system.
Provided that such a message is displayed no later than five minutes after the race has finished the driver or drivers concerned may not leave the circuit without the consent of the stewards.
16.3 The stewards may impose any one of the penalties below on any driver involved in an Incident:
a) A five second time penalty. The driver must enter the pit lane, stop at his pit for at least five seconds and then re-join the race. The relevant driver may however elect not to stop, provided he carries out no further pit stop before the end of the race. In such cases five seconds will be added to the elapsed race time of the driver concerned.
b) A drive-through penalty. The driver must enter the pit lane and re-join the race without stopping.
c) A ten second time penalty. The driver must enter the pit lane, stop at his pit for at least ten seconds and then re-join the race.
If either of the three penalties above are imposed during the last three laps, or after the end of a race, Article 16.4b) below will not apply and five seconds will be added to the elapsed race time of the driver concerned in the case of a) above, 20 seconds in the case of b) and 30 seconds in the case of c).
d) A time penalty
e) A reprimand.
If any of the five penalties above are imposed they shall not be subject to appeal.
f) A drop of any number of grid positions at the driver's next Event.
g) Exclusion from the results.
h) Suspension from the driver's next Event.
