Steering fail icon after a short trip

Thanks for the comments, here is a quick update drove to the garage today for the service steering was ok for most of the trip but returned just before I got there. The old battery was replaced as part of the work. The trip home was ok (headlights and wipers on) until I turned into my road when I got the warning but still had power assistance. The next step is to get diagnostics done.

It’s possible you could have a problem with the alternator, if you have a volt meter you can check thee voltage across the battery terminals, I think you should have around 12.5v without the engine running and around 14.5v with it running

With the e89 cars having ibs charging the voltage with the car running can vary from 12v to 14.8v depending on battery health and where in the charging algorithm the systems at

Just had access to a code reader and found A54B = faulty rack motor. This looks like a common fault for a car with this electric servo rack. Next step is to get it repaired. I have seen a different post on here re this and a company that fixes them at a fraction of the BMW cost. Next step is to remove said motor.
Thanks for any previous comments.

Hi a quick update on this, I sent the servo motor to ECUtest as found on a different post and they tested and confirmed the problem, repaired the unit. The motor is now refitted and all appears ok now.
A big thanks to the forum members for your comments and information that allowed me to repair this.

Good to know that you solved it and those guys did a good job..how much did they charge for it?

£255 plus postage and VAT total £325.80.
A lot cheaper than a new rack and labour at a dealer I guess.

When I had my ECU repaired, I found their link in eBay was the cheapest price at the time. £300 if my memory serves me right. Good that you have got it fixed
