BMW Z4 Power steering column – Common problem.

z4 power steering fault


This electric power steering column is a very common failure for the BMW Z4 built between 2003 and 2009. When the steering column motor fails then the steering will become very heavy and the power steering light will illuminate on the instrument cluster.


If you attempt to diagnose the steering fault then you will find that when you attempt to read fault codes or live data from the steering column, it will not communicate at all with the power steering system. If you have these symptoms, then there is a very good chance that you have the very common fault with your electric power steering column.

We offer test and rebuild for a fraction of the cost of a new replacement, with unlimited Lifetime Warranty, all within 2-3 working days

Hi, light of eps default came and went, sometimes no steering assistance at all.stop and start motor again solves for a moment the problem. Does code 611D and 6118 be common to you? Battery and check of electrical tension and alternator were OK. Could it be an internal problem of the ECu of EPS? Thanks.
ECU Admin says: 07/09/2022 09:39:40
Hi, if all the feeds to the unit check out as OK, you may potentially have a faulty EPS
