Power Steering Failure

For that I'd have to pull the entire steering column out, which is something I don't fancy doing atm
Will first see how this summer treats my EPS, maybe it will get better... I'll save up for next winter to buy a new/repaired column.

I wasn't suggesting a drastic strip down quite yet! It's just a useful reference to see what the system is made up of :rofl:

I'm pretty sure you will can fix it without replacement if you methodically work through the suggestions on the forum, the problem won't be anything new. Keep us updated :thumbsup:

Power Steering Failure

Post by Tamir » Thu Jul 02, 2020 5:39 am

I finally managed to get a replacement steering column, only to find out that my Z4 now suffers from the infamous sticky steering problem. Has anyone experienced sticky steering right after installing a newer column?

My first guess is that the specialist who installed the new column had sealed all parts so tightly as well as the motor to the column that there's no free space for the wheels to try and go back to the "0" angle.

I must say it ruins the experience driving this car. The thing I like the most about driving my Z4 is the precise steering and how light the car feels in high speeds and in turns. This issue gives that all away. Not to mention I feel it's dangerous to drive it with the sticky steering, I find myself making small adjustments so I don't crash into the sidewalk or cars coming in front. Feels like riding a bike. :(

Will keep the post updated, and will appreciate any helpful input. :driving:

Try and adjust the concentric ring, the part where the motor fits to the column. It needs very slight adjustment either way to see if the steering gets better.
It helped on my sticky steering

I tried to move it left and right but it's very tight, couldn't move it not even 1 mm :)
To your knowledge do I need to take the part out again or can it be done from under the steering wheel?

No, you undo the bolts that hold the motor to the column, just enough so you can move the ring. Mark the position before you move it. Then try about 5 mm at a time.

It's been a long while to get this sorted but it's all fully functioning now, finally. Thank you for sharing your wisdom and experience when it comes to Z4's... You literally helped me save lots of cash. You stuck with me ever since the first post on here and I appreciate it! :driving: :thumbsup:

I'll echo that. Everyone on here is very keen to help others with their problems.

After reading several threads on here and in no small part to Firebobby's advice my EPS has been fixed.

Although I have not got my car back yet Ross at RBM has removed and refitted my EPS motor/ecu and confirmed it is working again after being sent to ECU testing for repair.

Ross also had another Z in with the same problem and ECU testing's repair again fixed that.

It does sound like your ECU is going faulty.
When you have the problem, is your sports button mode still working
