The BMW Z4 steering system is powered by an electric steering column. The electric power steering column works well in refining the steering and handling as well as increasing the vehicles fuel economy because unlike a conventional belt driven hydraulic power steering pump, the electric steering column does not rely on engine resolutions to produce it’s power and therefore does not drain as much power from the engine.
Common BMW Z4 Electric Power Steering Column Problems
The symptoms listed below are indications of a faulty BMW Z4 Electric Power Steering Column:
1. Intermittent loss of steering, which returns once the ignition is turned off and back on again
2. Heavy steering in one direction, but light in the other
3. Steering vibrates when turning
If any of the above faults sound familiar and are becoming persistent, it will more than likely mean that your electric steering column is damaged or faulty. Going to a main dealer if the power steering column is faulty could cost you in the region of £800 + VAT (Plus labour + coding), and it may only come with a 12 month warranty. The alternative option would be to buy a used second hand unit, but the risk with this would be that you would have minimal information about the previous vehicle and how many miles were covered or how well the vehicle was maintained, therefore there is risk of the electric steering column failing again at some point.
