Hi,
Okay, it's not specifically related to TDI technology, but I'll give it a try anyway...
The windshield wiper heating is no longer :(.
All the fuses in the fuse box are okay, but still no power is coming through. Is there possibly another hidden fuse somewhere, like with the heated mirrors?
Unfortunately, I'm missing the correct wiring diagram, and it would be great if someone could help me find it.
