Mein Auto: X1 sdrive 18d

The steering in the non-Servo sDrive was way too light.

Can anyone share similar observations?

My suggestion is to try the non-Servo sDrive to see whether you prefer heavier steering before electing Servo. Servo EPS steering is not too light, though I'd prefer even heavier, and pretty close in effort to an HPS system w/ Servo.
The new X1 sDrive 16d ships with EPS but this is not an option for the sDrive 18d and 20d which ship with mechanical hydraulic steering that vibrates, especially when you are parking.

The basic mechanical hydraulic steering on our 18d w/o servo is very heavy but its response varies with speed. So just what the servo adds is a bit of a mystery..

I have yet to see a new X1 with EPS but have driven a Series 1 116d with EPS and it was a lot lighter and easier to handle, and for me the larger and heavier X1 would benefit from EPS.

You can tell which system you have by turning the steering wheel to the limit. The older mechanical hydraulic steering vibrates horribly and there is a strange noise present when parking..
