Well, as the title states... I'm having a bit of trouble finding the plug for VAGCOM etc. to plug into on my S3. I was under the impression that it was just under the ashtray/cigarette lighter compartment, under the little cap that comes off at the back of the rubber mat thingy? I took the little cover off, expecting to see a plug there for the diagnostics to plug into, but instead just found an empty hole into the bottom of the dash. I assumed that the plug had slipped out or something and took the dash apart, but still can't see any plug... just a few receipts and a chewing gum packet from the previous owner. Any ideas?
