Nico Rosberg was left to rue a mistake on his flying lap in Q3 ahead of the Chinese Grand Prix.
Rosberg set the fourth fastest time while team-mate Lewis Hamilton claimed pole position.
"A very good team result today and P4 is a decent grid position for me," he said.
"I wasn't able to do my qualifying simulation this morning due to the hydraulic problem which was a bit unfortunate."
"So I needed to catch up through the qualifying sessions and find my way. I took some settings from Lewis for the initial set-up which worked out well. I made a small mistake at the last corner on my lap in Q3 which cost maybe a tenth and a couple of places."
Rosberg, who won in China last season, believes that he is in a good position for tomorrow's race.
"I'm in a good position for the race and we've worked a lot on the race performance this weekend so I hope we can gain some places tomorrow. It's going to be an interesting race with some of the guys starting on the medium tyres so let's see what happens."
