So I have a C7 A6. I emergency braked and had full lock up. I since tried it multiple times, I might feel a hint of the grinding feeling (as if it is working), though for the most part, just lock and skid. I have scanned my car multiple times, no codes. I have tried disconnecting the battery for half an hour, no help. Anyone heard of such a thing or have any thoughts?

I had a thought last night. It is possible that the ABS was working previous to my rear brakes being changed. It is a faint recollection, but I think I recall it being the case.

Never heard of such a scenario, but there is always a first!
  • if a sensor is bad you will get a code.
  • if a sensor cable is not properly connected or broken there will be no feedback and so you will get a code.
  • Any splice anywhere in any wire will interrupt feedback and you will get a code.
  • If the pump is bad you will get a code.

The only thing I can think of is the pump is on it's way out. Not completely gone, so no code, but enough to give a sense of no ABS.

There is just as easily a good chance of a blown fuse. Get down there and find ABS and also brakes. I'm betting your fuse is blown. Yes it has one.

Thanks for the replies. So I have done some further testing and found if I juuuust break a bit of traction, I will get abs. If I fully lose traction, total lock up. If I go off the brakes as Im locked up and go straight back on, full abs! It is pretty wacky! I have checked the fuse, even though there is life... It is fine and well yeah, the ABS is proving to be alive.

Not sure I understand what you mean by "break a bit of traction". If you bring it up to about 30mph (48kmh) and slam the brake pedal down on dry pavement your ABS should kick in. If not you have a problem. Hope you work it out!

Well the first time it skidded, it was dry. All my subsequent tests have been in wet conditions to reduce damage to my tyres. By "break a bit of traction", I mean a light skid, not heavy. I definitely have a problem! I've booked it in with Audi as I'm out of ideas!
