WA - mk4 4motion guru?

[Perthdisco]

Thanks for the advice guys. I have ordered the brake switch, so that will be a small job for next week when it gets here. I've checked the ABS measuring blocks ch 1, 4 and 6. the speed lines up, and I think everything else is in spec (though the YAW rate was a bit high in one of the checks?). Here are the readings at 0, 30, 40, 50 and 60kph (While I have the latest VCDS, I'm not that clued up on what its telling me):

What is the code reader device you use?

All of those readings look within spec unfortunately and I'm fresh out of suggestions.

If a brake switch doesn't fix the problem then I can only conclude you need a new haldex controller

ok, so it wasn't the brake switch. I eventually sourced a haldex controller from a wrecker in QLD, and got Joe down at Elite Euro to see if he could find anything else it could be, which he couldn't. fitted the replacement controller, and all is now well..
