Just got these both at the same time today, during each start after ~5mph.

I washed the car yesterday so maybe I got a wheel speed sensor wet? Although idk how that would affect power steering. I did just do ESL repair but had no problems yesterday, so it can't be that...

Any ideas? Every thread on this has a different answer.

I had the same issue. Restarted the car and it went away. I ended up replacing all 4 speed sensors just in case but that wasn't for almost 2 months after and during that time I never had it pop back up.

So, I checked the wheel speeds on each of my sensors and the values were all consistent with the speed. So it can't be that.

Battery isn't low, as its brand new.

EDIT: When I did my ESL, I may have failed to plug in the brake light switch properly; I will have to check tomorrow.

Could be just a glitch. I had the ABS and Traction control light turn on after 5mph but not the power steering. It happened twice in my ownership and it just fixed itself after a few starts and recalibrating itself I guess. I noticed this happens after I unplug the battery. My guess is the ESP/ABS gets reset and takes a few driving cycles to relearn the data.

The first time these lights came on, I was very close on buying a new ESP module but as I arrived to the part store, the lights came out. I remember having the battery disconnected not long before that so i know what caused it now.


Don't throw parts at it and just drive it for a week with the lights on, surely someone with a STAR diagnosis system can probably calibrate it but from my experience, it can do it by itself. Strange for the power steering error, however, mine was only ESP/ABS that was malfunctioning.

Any Update?

Adi-Benz

No, it's only been a few days anyways. Before yours happened did you do any work to the vehicle?

Nicholi2007

I did a wheel swap but everything was fine. It's been well over a week since that was done

Try unplugging the battery for a few hours. It won't clear the lights but it may help reset the calibration process.It worked for me but like I said, it did take a few days and driving cycles for it to clear up.

I guess I'll have to try that

Haven't really done anything yet as I'm just too busy, but I learned that cruise control doesn't work anymore with this error.

Also it seems like 5 other people are having this same problem at the same time and no results...

One more to the list . have the exact same issue and it's driving me nuts as unable to fix the error

Mine would act up once every few months and then would work again for a while, very annoying. I found a used low mileage ESP module with the same part number and coded it in, hasn't given me trouble since.

Happened twice now, this time it won't reset itself. Sick.of this car now, fault after fault.

Nicholi2007

It still happens to me every once in a great while. I turn the car off and restart it. It goes away.

You need a scan to see what comes up. It could be the module. It could also be other things.

See this video as it covers the possible ABS error culprits.
