Hi, i want to thank you a lot for you vid mate, my E90 had EPS failure and thanks to you i checked the ground wire, it was all dirty so i just cleaned it and since 3 days everything works well again. I would never had guess this problem without your help. Keep it on !

[@fredbach6039]

Dan I sure appreciate your teaching style. You mention that Eric O was probably the best technician. Yes, I could agree with that. Eric does teach us, but your theory lessons are better organized.

[@lawsautomotive108]

Good video Dan,. Good old fashion "VD" voltage drop. I do think Flexray is going to be used for all new vehicle's, and for autonomous applications via ADAS. Flexray speed is 20Mbit/sec through the gateway into the ADAS system and steer by wire systems all we have to do for the limp home mode for that situation is get the computer to turn on your four-way flashes cuz you're going to be coming to a fast stop. With the LIDAR system and ADAS it'll be able to pull you over fairly easily having 360° view of all surroundings.

I want to learn more! Nice repair. I would have covered the bare terminal with silicone sealer. This connection is in the path of corrosive elements, bad choice on BMW’s part. Solder and heat shrink is the only option for any permanent repair. Here in America, the majority of mechanics think it is proper to use crimp connectors and call it fixed.

Good one Dan your got skills sir. EPS its great they said.. what can go wrong by reinventing the wheel? 🤔

[@vin605]

Diagnose Dan did it again 👏

[@EXOVCDS]

Awesome video Dan! I used to see "fried ECU's" on mk2 VW's due to a bad battery ground cable going to the transmission or people not attaching the cable after a clutch replacement (starter tries to ground through the ECU). Dan Sullivan's "LoadPro" in action... with no royalties going to him. =( (I hope I have my facts right... my apologies if I don't).

[@Diagnosedan]

Thomas EXOVCDS positive voltage will always try to find a way to ground, when a big ground cable is bad the current can start to flow thru a smaller cable or circuit that was not designed to carry this current ( like blowing a fuse) the circuit can become overloaded and fail.

[@EXOVCDS]

DiagnoseDan On older vehicles, if I see a high O2 Sensor reference / bias voltage, I check the grounds for the ECU. I will have to keep this in mind for other modules / systems! Thanks again, great video!

[@Diagnosedan]

Thomas EXOVCDS if a voltage is higher than you would expect always check the grounds! It is almost 7 in the morning here i guess it's bedtime in Canada😂

[@TheMechanicalStig]

I found something similar to this on a VW Tiguan, no power steering assistance and no communication. It had corrosion on the ground besides the battery, just cleaned it and it worked instantly.

I had a buddy help me with replacing the control arms on my 2011 bmw f10 5 series. After watching one of your videos. When we were torquing down the bolt on the back wishbone arm that black cord on the steering rack with the 3 wires got stuck behind the bolt and went un-noticed. When we were don’t the power steering wouldn’t work. Not sure how to fix it I got the wires from behind the bolt and had to solder them together and still no power to the steering rack. I’m not sure what to do… or what had happened

[@thingsido6067]

Ik heb dit juist voorgehad met mijn F30 (2012) Heel plotseling ook, auto 's avonds geparkeerd, 's morgends willen vertrekken en geen EPS meer. Kwam er nog bij dat mijn RPA systeem uitgevallen was en mijn tractie controle, staat dit in verband met elkaar? Ik moet er ook wel bij vertellen dat ik 2 weken voorheen een nieuwe dashbord cluster (instrumenten paneel) heb moeten laten vervangen omdat alle indicatie lampjes begonnen te flikkeren. Ik heb wel niet dezelfde met het kleine digitaal schermpje maar een 6WA met het het grotere digitaal scherm laten installeren met een extra MOST kabel om de boel te doen laten werken. Goeie video trouwens, als ik mijn wagen terug heb ga ik dit eerste werk nakijken, beter nog laat de garagist dit filmpje zien en we kijken het samen na

Doesn't happen often but worth checking

[@HristovRumen]

In essence, what you're saying is that, if you first replace the rack with a new one, the new $2000 rack will get fried before you've even had the chance to realize there's an additional problem.... now that's some "excellency" in engineering. Congrats to you bmw.... you've "done" it again... f*****ckin BMW! I ran away from that garbage coaster brand a long time ago, now realizing that my decision to never return was the best I've ever made!

Hello DiagnoseDan what scope equipment model Number you use with your laptop?

[@Diagnosedan]

Gmto scope with Atis software visit the Ryans Automotive website for more information

[@ecisnerosvivas]

Dan: Thanks!...you’re the best!

[@diagnosticcheck9803]

I'm pretty sure that the bad ground (high resistance, low current flow) Didn't cook the module. You would need excessive current flow which you dont get from high resistance. Great video tho keep em coming

[@Diagnosedan]

Diagnostic Check, try to jumpstart a car using a speaker wire, it will work but it creates a lot of heat in the wire and the wire would eventually fail. There was no ground on the Eps but still there was enough current flow to raise the voltage in the flexray wires.(It did not even light the test light). And the electric motor was not working at this point. Now imagine the point where the Eps was still working but the ground was starting to get bad.

[@diagnosticcheck9803]

DiagnoseDan does starting a car with a speaker wire damage the starter motor in any way? I don't think it does due to there being a voltage drop/less current flowing. When has a bad ground/live EVER caused the component designed to be in the circuit to fail?

[@kaistlouisss]

Diagnostic Check if the path to ground is through a pcb that can’t handle the excess current flow it will burn, no? The way I understand it the motor wasn’t burnt, the module on the motor was toast

[@felixcat4346]

Diagnostic Check, there is no arguing with a KZbin provider trying to make a dramatic or shocking point. He's making egregious claim like you can run enough current through speaker wires to turn a starter. It just not going to happen.

[@mariusvaida]

Hi Dan. I have a 2012 BMW X3 and has an intermittent error (steering malfunction) when I start the engine, but no steering issues after I confirm with an OK on the dashboard. absolutely random ( for example now it is 3 weeks without and error, but I had days where it comes up in the morning). Someone mentioned the ground wire at the batttery. Is this a common problem?

[@平間豊-l5h]

Hi, I have been enjoying your video. Since I have owned a BMW Z4 E89 and recently having tech issues on the EPS, I would like to obtain your views on replacement parts. BMW Dealer here says the car can be fixed by exchanging whole steering column. But cause of problems was faulty EPS motor. So I have done separating motor and sent to a professional for rebuild. The fixed motor was back on the steering column and car is fine now. Shall we relay on assembly parts exchange based fixing for long term reliability or finding the real cause of problems and replace individual parts for saving costs?

[@Diagnosedan]

@@mattyholt14 it goes to a sensor in the rack itself.

@DiagnoseDan should the feed wire next to the communication wires on the 3pin plug be a 5v reference voltage? Sorry for all questions😆

[@philipriesling3897]

Hi there, very nice video, thanks a lot. I have mechanicly bad steering rack . Got another and swapped the EPS units thinking car would think it is the same EPS but did not work. Is it possible to get a replacement rack and stick original EPS to the motor or they go as a pair? I did just that and getting CD951B message - actual steering torque driver actuator/actual force rack , 49.0.2 - signal invalid. I suspect that EPS and torque sensor on the rack don't like each other.Reprogrammed, recoded using ISTA but with no avail

[@Diagnosedan]

They are calibrated at the factory

[@islanddiagnostics3925]

Is the steering rack serviceable? I am working on a F13 650i and the torque sensor in the steering rack is bad.

[@michaelhanglow5051]

Did you only replace the electronic motor or the rack and pinion assembly as well ? How much for the new parts caused by a bad ground? Sounds like an expensive fix for such a simple failure.

[@Rockardo_]

Had a similar situation with a g12 at work, flex ray communication faults and all but it just ended up being the power supply wire being pinched and ended up causing on open in the circuit

[@roanb856]

Mijn power steering werkt ook niet… Als ik de hoofdstekker verwijder van de EPS (2 dikke kabels) en daar de spanning vanaf meet, komt er tot mijn verbazing geen spanning uit. Zekering nagekeken en deze zijn in goede conditie. Wat adviseer jij? Zijn er wellicht ook printplaatjes die het kunnen begeven? Ook geeft hij geen foutcodes aan..

Hello, I have the exact same car, F20, and I had a warning the other day about EPS fault, I pulled to the side of the road, turned off the car, turned back on, since then there is no problem. Could this be a one time thing? The car is just out of oil change and general service. Is it a possibility that the service guy worked on a nearby area to the EPS and moved those cables out of their places, or something? Should I be worried? Wait for another fault ?
