Fault codes 4AB2 and 43F1?

Hello I get this fault codes when checking for error codes in my 320d E91 LCI. The car has rest heat. It's a function you can press on when it's cold outside and you have turned the engine of to get hot air to the coupe. Do you guys think it has something to do with that function. The rest heat has an own pump that only work to the rest heat. It stopped working this winter. But just for a test I took a hammer and banged the pump a few times. And it began to work:-). What do you guys think about the fault codes? Btw this is the pump nr 4:http://ift.tt/1TiXq0E

Appreciate all help :-)
