Hello Gothaur,

thanks for you question. You're right, the steering pump sits behind the seats. There is a word missing. I've meant steering pump system. Sorry, English isn't also my first language – i'm from Germany.

The hydraulic steering gear box is located in the lower front. There are some valves in there that can do noises. See attached photo.

On the right front side there is also the brake booster. If you open the frunk you should hear if it's coming from there. Intermittent interval could maybe be caused by the ABS system checking pressure. But in general this should lead to a warn signal.

Did you put the car on a diagnosis system and check it for error codes?

Regards, Markus

Thanks Markus: next time I hear it, I will follow your suggestions.

No, not recently at least, but I will in 10-15 days.

Cheers!

After a 150 km highway drive, once the car was about to be left in the garage, the sound was there. The wheels weren't turned at all. I opened the frunk and... it went away! So I closed the frunk. After a few minutes (engine still running) it did it again, just once (straight wheels), and then disappeared.

Alongside this issue, if I drive the car for more than a little (just to have it warmed up), I hear a clunking/knocking noise coming from the steering column, like something has got loose. I feel something even through the clutch pedal and the steering wheel. At low speeds (10-15 km/h) it's very, very clear, particularly when the surface isn't perfectly even. It does it more going downhill than uphill. It sounds like CLO-CLO-CLO-CLO-CLO.
