Good question, I borrowed the device from a nearby audi workshop. it's an OEM device, not an ebay cable.

Anyone hear of this? All other modules work perfect and allow me access in VCDS just not the instruments anymore. Just times out and say's it's unreachable.

From a nearby audi parts guy. I would check all wires from the tanksensors first before installing a new cluster.

I am more interested in a good answer. Everything I read about Vag Taho says that it can't adjust A8 D3 odometer. Another thing that doesn't fit is Component Protection. A8 cluster has it for sure. So version you used is important. Have they improved it lately?
