01486 Audi A3. Can't turn light off

[AudiLeon]

The A3 has been playing up on the brakes for ages now. I've not got round to pressure bleeding the system. I was using Vagcom earlier and told it to bleed the pump. The brakes are tons better now. So I know i need to bleed the system tomorrow now. There must've been some air in the pump.

But, whilst playing I managed to engage the system test.
So I now get:
01486 - System Function Test Activated 35-00
in my faults.
That is the only fault showing.

I've read up on how to turn it off.
It says standing still, press the brake firm and the light should go out. When I start the car the esp light isn't on. Just the ABS light. I press the brake and the esp light starts to flash. If i drive and brake for a abit, the esp goes out. I've tried the turning part of the setup and the abs light is still on.

Any ideas?

8P or 8L

Sorry it's an 8L. 2001

I did something like that on my 8P by accident using VCDS. I had to drive in circles at a certain speed one way & then another for the car too to complete a test of the systems lateral & longitudinal sensors.

 

[AudiLeon]

I've tried that, won't do it

 

[NHN]

Disconnect battery for 20 mins then see if reset itself.

 

[AudiLeon]

Have you heard of that working before NHN?

 

[NHN]

Sometimes a module gets locked up, confused, removing the power allows it to power reset as such, make sure you have your radio pin to hand incase.

Certainly worth a try as I've known various modules to get confused as such.

 

[AudiLeon]

Been out and disconnected it. Fingers crossed it'll fis the problem!
It has an aftermarket cd player thankfully.

I'll let you know!

 

[AudiLeon]

Well, reconnected. Still doing the same. Took it out, tried doing circles and changing direction at low speed. No luck

 

[Khufu]

how low? I was doing figure of 8's at 30mpg - tyres were screaming like mad LOL.

Have you tried it this way?

[AudiLeon]

Between 5 and 20mph.
Yeh I tried that, still no luck

 

[Khufu]

did the link work for you? Ive just tried it and it didnt work.

 

[AudiLeon]

it needs a ) on the end bud.

 

[AudiLeon]

Still got this issue

 

[AudiLeon]

The Mrs told me she went over a hard bump in the road the other day, hard enough to lose a centre cap. grrr. But it's actually reset it. Fantastic!

 

[Khufu]

Thats weird. I hope A) the alloys not buckled B) you have to avoid any bumps in case is comes back on!!

 

[NHN]

Well thats got me aswell, I do wonder if the system function test is based on a distance at which point it disables, strange one, have to ask RT if they know.

 

[Khufu]

I've been there with that test!!!! - you have to start the tests while the ABS light flashes when you 1st start the car up but RT says it cant be cancelled once started.

We have a Special Note on the Bosch and Conti/Teves pages about contacting us directly if the test will not end on its own:

ESP System Function Test (Conti/Teves) - Ross-Tech Wiki

ESP System Function Test (Bosch) - Ross-Tech Wiki

Depending on the module, a specific Basic Settings procedure generally disables this test. This varies, so we do not have it listed on the Wiki and evaluate Auto-Scans from registered users to determine the "fix".

I'm sorry I missed this post earlier!

 

[AudiLeon]

Quite ok Dana,
I did email vcds and ask for advice, but i bought my unit second hand. Is there a way i can reregister?

 

[NHN]

You would afaik have to pay the software license fee amount, I'm sure Dana or Bruce can confirm this for you mate.

 

[bearthebruce]

NHN, you are correct. To receive tech support from Ross-Tech on a second hand purchase, you must pay for a license as the original license is not transferable from the original party to another. Tech support is only offered to licensed users. Please see the VCDS Used Dongle Registration
