Hello to everyone, I am writing from the sunny island of Singapore. Just picked up my MY01 silverstone S2000, and notice the following.

1) Quite a fair bit of rattling - expected of a roaster I supposed
2) Juddering of steering

The 2nd problem really puzzles me. Usually happens if the car hasn't been driven for say 24 hrs. When you first start up the car, and am trying to manuevre the car out of a parking lot, where there's a lot of steering turning, but very little car movement. The steering wheel will start to judder, it is like shaking violently, and feels like sudden give and catch. However, there's no problem when the car is on the move, even if you do U turn etc.

Is this a characteristic of the electric powered steering, or is there a fault in my system?

Thank you in advance.

 

What is your engine rpm during these events? The power steering is not known to do this typically. Maybe at low rpm, your charging system is not putting out enough power to keep the EPS happy. Check you charging system voltage or check your idle speed.

I've been taught in my professional driving course that this is one of the worst things you can subject a power steering system to. Always try to have some tire rotation before cranking on the steering.

 

I usually control my clutch quite well, so don't think I would have allow the engine RPM to drop below idle. The only thing is that the battery is kind of old, perhaps there's not enough buffer to keep the power steering happy!
