does anyone what the triangle in a circle warning light? 
I have the abs warning but there’s no fault found on my code reader 

If you are using a generic OBD11 reader it won't connect to the ABS you need a VAG specific reader ideally VCDS

Would a code reader such as autel be able to pick up this code?

Yes. Do you want me to tell you what your car manual says? I mean that's all I know. OK, all right then, that's a brake system fault, quite possibly a worn left hand inner front pad.

What code? Cars had warning lights before people thought they needed a computer for everything and that they could control the world from their phones.

 

It's a brake warning light, check the fluid reservoir level and visually inspect the front brake pads, both of these will set off the warning light but there is no OBDII code for them anymore than there is one to say your fuel tank level is low.
