Hi All,

May I ask for your advice in the following matter. Please excuse me if my English is not perfect, I am writing from Hungary, English is not my native language.

I have a w211 E 200 kompressor from 2006 (facelift model) with 85.000 km mileage, and I experienced slightly heavy steering and some juddering, vibration on the steering wheel when turning at low rpm.

It was like that from the moment I bought it which was a month ago. I saw a leak on the high pressure power steering hose, thus, I attributed the issue with the steering to the leak. I had the high pressure line replaced with a rebuilt hose as I could not find any OEM factory part. The symptoms changed a little bit with the rebuilt hose but did not go away completely: the steering has become a bit more noisy and there is still a slight vibration, juddering on the steering wheel, and the steering is harder than it is supposed to be. It is more noticable at low rpms, when turning the wheel left and right with a standing car or when parking. It gets better at high rpms but there is some juddering and vibration when you turn the wheel fast left and right (which often happens when parking).

As the problem was not solved with the rebuilt high pressure line, I replaced the pump too to no avail. The problem is the same after installing the brand new pump too.

Took the car to a steering gear specialist who said that in his opinion the steering box cannot produce such symptoms I described in a car with such low milage (85.000 km) and the issue is not typical. He suspects that the rebuilt high pressure hose might not have the exact same characteristics as the factory hose and that might cause the issues. He told me that based on their experience only every 1 out of 10 rebuilt high pressure hoses can do the job well. He advised me to have the rebuilt hose replaced by an OEM factory hose and the issues with the steering will probably go away.

The car is not wandering on the road, steering is precise, there are no clunking noises and anything like that. It is only this slight stiffness of the steering and the slight juddering, vibration on the steering wheel with some noise from the hydraulic system but not from around the pump.

Does anyone have any ideas of what it could be? Do you think the rebuilt pressure hose could produce the said symptoms with the steering?

I love my car but this issue really pisses me off and am trying to find a solution.

Thank you for your kind attention and your advise in advance.

All the best to Everyone,

Adam

Yes, the system was bled of air and there does not seem to be any air in the system because I don't see bubbles or foam in the fluid in the reservoir with idling engine. I would like to believe that it's the high pressure hose. If I Rev up the engine to 3-4 thousand rpm the issue is barely noticeable and there is no problem at all when driving. This tells me that the problem is that the rack does not get enough pressure, and when you Rev up the engine causing higher pressure coming from the pump then the steering gets much better. Do you by any chance know a source for oem factory hoses in the UK? I see you live there. Many thanks.

Shop OEM part # a2114665281 or 2114665281. If you want confirmation post VIN.
Thank you for the oem no. The problem is that I am not finding this part anywhere online within Europe. I found one on ebay but that's in the US and they don't ship to Hungary. I am afraid I will have to go the dealership.

Thanks to EU laws you cannot buy genuine MB part outside of MB dealers network.
