    Take a look at the Ross-Tech wiki :http://wiki.ross-tech.com/index.php/17536/P1128/004392

    Also, take a read of the Fuel Trim page on Ross-Tech's site: http://www.ross-tech.com/vag-com/cars/fuel-trim.html

    There are a number of things that can cause the lean fuel trim error. You have to start looking for them. If the trim is lean, often there is an air leak into the system somewhere. Or, there could be something going on in the exhaust system that is causing the ECU to set a lean condition. It could be a bad sensor although you would normally see an error code for that sensor.

    By giving you the information about how the car calculates fuel trim, I was hoping to help you narrow down the possibilities. Sorry the information is not helpful.
