BMW E46 Series – Power Steering Pump Issues.

Field reports have shown that some BMW E46 Series can have issues with the Power Steering Pump.

The BMW E46 series power steering pump has been designed extremely well, but we have seen premature pump failure in this series of BMW.

The design of the pump shaft is the issue, the shaft has been manufactured with a reduced end that the internal pump rotor locates onto, this also allows for the ease of assembly of the pump. The main shaft in the pump can develop a crack, when the pump is loaded i.e. the steering is held on full lock, this crack can completely shear-off the inner end of the shaft. When this happens the vehicle will have a complete failure of power steering assist.

If your vehicle has no power steering assist a quick way to check to see if the shaft is broken, is to check the pump pulley end float. If the pulley can be moved in and out more than 15mm the shaft is broken and the pump will need to be replaced. (Please note that end float in most power steering pumps is normal approx 1mm to 3mm)

We have now sourced a supply of new Power Steering Pumps for the BMW E46 series, at a cost effective price, so please give us a call to see if we can help save you money.
