There is information on this American site. They always seem to have more recalls and issues than anybody else.

Seems to affect all models using the 3L TFSI engine around 2011-2012
Description of Defect :
Description of the Defect : Due to a combination of production tolerance issues and vehicle vibration during
dynamic driving, it is possible that, in rare cases, a fuel leak may occur in the
vehicle's fuel injection system. Leaking fuel, in the presence of an ignition source,
may result in a fire. There have been no reports of accidents or injuries as a result of
this concern in the United States
Description of the Safety Risk : Leaking fuel, in the presence of an ignition source, may result in a fire.
Description of the Cause : In rare cases, unfavorable tolerance conditions can lead to a minor leak at the fuel
rail / injector connection.
Chronology :
• March 2013 - August 2013: The first customer complaints regarding fuel odor coming from the engine
compartment were received. Field investigations were conducted, including analysis of engine/parts
tolerances. No abnormalities were noted.
• September 2013 - January 2014: Conducted test bench analysis, with no abnormalities noted.
• February 2014 - December 2014: Further analysis conducted, including simulations of different parts fitting situations performed on defective parts/vehicles. Analyses concluded that, if the valve is positioned unfavourably in the range of tolerance during dynamic driving, a small leak may form at the connection between the fuel rail and the injector, which then causes fuel odor.
• January 12, 2015: Recall decision made.
Description of Remedy :
Description of Remedy Program : Replacement of fuel rails and the corresponding seals.
How Remedy Component Differs from Recalled Component : Optimized geometry/tolerances of fuel rail and improved sealing.
Identify How/When Recall Condition was Corrected in Production : Implementation of reinforced fuel rail
