Hello to get the emissions light then this usually means there's a fault with the DPF ( diesel particulate filter) or one of the oxygen sensors in the exhaust if the ECU thinks the DPF is blocked then it won't allow full engine power so I'd suggest; taking the car for a long drive where you can keep the engine rpm up over 2000 rpm for around 30 mins this will get plenty of heat into the system and get the system into re-gen mode if that doesn't help then consider http://www.dpfcleaning.co.uk/
