Audi A5/S5: Diagnostic Port Location

Translated on 28-09-2026, 1:16.

Hello, could someone perhaps tell me where I can find the diagnostic connector on an S5?
Thank you very much.

Perhaps it's located in the same place as in all Audis? Specifically, in the left part of the driver's footwell, like in the current A4?

I worked part-time at the club during the holidays, and there, near the driver's door, the diagnostic connector was still hanging loosely from a relatively short cable.

Okay, thanks, I'll take a look and let you know what I find.

I don't have an A4 printer available right now.

I'll find it myself, thank you very much.

Stick your head into the footwell on the driver's side and look upwards.
You'll only find a square, 16-pin 'color blob' in that black

Right, it's located all the way in the back, on the left side, next to the clutch pedal.
