Heidfeld very disappointed after problem-filled Friday

BMW Sauber F1 Team driver, Nick Heidfeld, had a disappointing start of the Chinese weekend as in both sessions he suffered a hydraulic leak. The gearbox of Heidfeld's F1.07 had to be changed twice by the mechanics.

Nick Heidfeld “Of course I’m disappointed because I was not able to do a lot of driving today. In both the sessions I had an hydraulic leak which meant a gearbox change. The mechanics did a great job, but the track conditions were also changing and, therefore, making any sensible comparisons impossible.”
