Gearbox fault

Hi all, got an issue with my 2012 evoque gearbox fault reduced traction message came up. I've tried changing the auxiliary battery but it still comes up. Also the DSC On message comes on (even though its already on) just before the gearbox fault message appears. I got a diagnostic device and the fault code comes P 1889 14 Oil pressure pump performance. Anyone had this before and what's the best way forward. Many thanks Andy

Best bet is to post on the Evoque UK forum. It's seen by a lot more folk
