F20 116d front end / steering knocking

Post by 120d-ave » Tue Mar 14, 2017 6:01 pm

Hi all,

I have had a knocking noise coming from the front driver side since I got the car about 6 weeks ago. It doesn't knock under normal driving conditions but mainly when going over bumps when turning left. When the car is stationary with the engine running the steering group makes a dull knocking noise when turning the wheel as shown in the video



I took the car back to the garage after a couple of weeks and after looking at the car said they couldn't find anything and said to bring it back if it continues....which it obviously has. Any ideas what this could be?

Hi, my f20 had this exact issue, after a few trips to the dealer and 1 new steering rack, the issue was fixed. I was speaking to a friend who is a mechanic at a big car sales (trade centre wales) and he said they can be repaired rather than replacing the whole rack, but don't quote me on that.

i cant play your video at the moment, so check the video in the thread i posted a while back if you want to compare the sounds.

Just checked out your video and that the same noise as mine. Looks like I'll have to get it back to the garage before my warranty is out.

My 2014 116d did the same and had steering rack and steering column changed. Has been fine since. Done under warranty.

Yet another driver with front end knocking.

Steering rack is a common problem I'm afraid. Some get replaced under warranty others don't. "They all do that sir" may be the reply from the dealer.

My rack was replaced along with the driver's suspension strut and tie rod end (over 3 or 4 visits to the dealer). The knocking went away for a few hundred miles but came back. I couldn't be bothered taking it back again, though now it's getting more notiecable and the warranty runs our in May/June so I guess I better get it looked at (as well as a list of other issues!)

Well after researching the steering rack knock fix I thought if give it a go after having no success with the garage I got the car from. I took the under tray off and located the 3-pin washer looking thing on the front driver side of the rack. I made a tool using some mild steel bar and screws to locate in the pin hole and turned the washer clockwise about quarter of a turn. After the initial test drive all seems to be ok with no knocking. Hopefully it will stay like this.

Had the same problem, loud knocking heard when vigorously moving streering wheel left to right.
Fabricated the tool with the three pins. Managed to tighten this washer thing up a little bit. Now the knocking seems to be gone. Hopefully the problem is now fixed.

Took it for a drive today and knocking is definitely gone. However the steering itself feels a bit too stiff. Probably needs adjusting a bit more. Will try to loosen the screw a tinie little bit and see if the steering gets better while still having no knocking noise.

Yeah, thanks for that. With some help from my other half I managed to find that sweet spot where there's no knocking but the steering feels nice and loose.
