I've noticed there are two part numbers with two different prices; Repair kit, control unit DSC (US$850) and Hydro unit DSC (US$1446). Given the error codes he has, which part would he need to buy?
5df0 - pump unit faulty = Repair Kit, control unit DSC?
5df0 & 5df1 - pump unit plug faulty = Hydro unit DSC?
I hope BMW recognizes this and does a recall fast!
9/10 times it is the DSC Unit. Are you in the US? If you are pm me the last 7 of your vin and I can get you a price on the unit.
