Steering wheel amber light

[Hos]

Hopefully a really simple one. The steering wheel light has been on for weeks now. Yet there isn’t a problem with the steering, the fluid level is good, and it shows no fault codes on diagnostic. 
is this a common easy fix?

thank you!

Have you had the battery checked? A failing battery can cause all sorts of electrical gremlins.

It’s a new battery, but can’t rule out it being faulty I suppose.

Ah, more unlikely it being that then. Unless not correctly coded to the car. 

Id guess a sensor. Not sure what diagnostic tool that's been used but it might need a more sophisticated one from Audi or an Audi independent specialist. 

Also a bit more unusual would be an issue with the instrument cluster.  

[Hos]

A sensor would be a good place to start. Thank you, I’ll look into that 👍🏻

Possibly related to your other topic regarding the radio. Also please confirm you have had the new battery coded to the car.

[Hos]

You have to code them to the car? How is that done?

[cliffcoggin]

I have not done it myself, but anywhere that has a decent diagnostic device should be able to do it. That does not include the cheap code readers that most folk have at home.

Any progress on this Damian?

[Hos]

No nothing yet. I haven’t had a chance to try it. A friend said he would plug it in when he gets time. Hoping that’ll cure it 🤞🏻

Hi have you tried sitting still engine running then turn the steering full lock left then right.

More likely steering angle sensor. Sometimes happens if car disconnected from battery for longer time period. 

I have vcds diagnostics, but couldn't adapt with it (or didn't know how to do it 🙈), but manual adapt did work. 

If you Google for Audi steering wheel adaptation, it should give exact procedure, as I remember , with straight wheels start engine, then do full lock to right and then to left(each side hold for 5 seconds), then get straight again , then drive for 20 meters, stop, do again full lock right to left(each side hold for 5 seconds), get wheels straight again, than switch off ignition for 20 seconds, start car again... If that sign haven't gone, have to repeat procedure... It took me like 5 times to do it, until steering angle sensor got adapted. 

Of course if sensor is in good condition, and other steering sensors are in good conditions. I had to do it after I was doing some repairs, and car was disconnected for over the month. 

Hope that helps.

A friend at work suggested that, but he only said lock it it over each way and hold for

5 seconds, and that should do it. But I can try what you said tomorrow. Hopefully that’ll work. It’s got a serious power drain at the moment, and I can’t work out what it is. So the battery is always dead after a few days.

As you mentioned earlier, you've got aftermarket radio installed, would suggest disconnect radio first, open glow box and remove rear parcel shelve , in order to see lights. After that lock the car, and come back in 10 min, check all lights are off, as car should go sleep after it's locked, and all lights should be off after 10 min. 

If car goes sleep, and disconnected radio not helping with battery drainage, the worth to get to car electrician, as there is way to find out which system draws electricity after car goes sleep.

It's a pity you didn't mention that fact earlier. It would have saved several of us wasting our time. It is not surprising you have electrical faults with false warning lights and a dodgy radio if the battery is not holding charge. Is there any other relevent fact you have not disclosed?

[Hos]

Sorry, No that’s all. I didn’t know that those issues may be linked. That’s why I’m here.  I’m still waiting for my mate to reset the battery. Hopefully today.
