Return pump error code or failure

[dgere]

hi,My X5 indicator/warning light shows up today after a long drive yesterday, (abs light, brake light and dsc light)..Went for diagnose today at a workshop n they said that my abs control module need to be change and cost at $3k including installation. But during the diagnose was done, the computer shows return pump error. Because of this i ask the workshop not to order first before i confirm this failure.Need some advice on this. i look into previous tread but didnt find anything about this thing.RegardsDgere
