The invention relates to a method for a vehicle system (100) comprising an internal combustion engine (10) having a turbocharger unit (110) connected thereto, a turbocompound unit (120) arranged to receive exhaust gas flowing from the turbocharger unit (110), and an exhaust gas recirculation system (130). The method comprises controlling the exhaust gas flowing through the exhaust gas recirculation system (130) by determining a pressure difference, and, if the determined pressure difference is above a predetermined threshold value directing the recirculated exhaust gas to an air intake line (160) downstream a charge air cooler (170), and, if the determined pressure difference is not above the predetermined threshold value directing the recirculated exhaust gas to a compressor (114) of the turbocharger unit (110).
