What power steering do I have?
I'm sure it's obvious to some of the knowledgeable people around here, but I am a little confused based on what I see under the hood.
From my reading I found that the Xdrive models have a hydraulic power steering while the rear drive models have electric. That's why you can have parking assistent on the rear wheel drive but not the xdrive. I have a 2015 550i rear wheel drive with integral active steering and parking assistent. But when I open the hood I can see a power steering fluid reservoir in front of the engine bay on the driver side. So... electric or hydraulic? |

Do you know if it also has a belt driven power steering pump to pressurize the fluid? Or is it electric? |

Yes, belt driven and runs at pressure, which is reduced off load. The xDrive models with HPAS, uses the same pump and ancillaries for the steering and ARS.

Are you guys with ARS seeing lots of body roll? 15 535i Msport with DHP/ARS had hideous amounts of body roll. More than any car I have recently driven. It almost seemed that ARS wasn't even present. Very very soft roll control. Especially in comfort mode. Things were a bit more flat in Sport mode. But still nothing like the table flat ARS in my old 2010 535i Msport with ARS. |
