I have a similar set up

I had some limited success on a 2016 A4, but it still wasn’t fully functional.

Thanks guys - that clears that up for me.

Hoping this is the right place to put this. If not, mods, could you move it please?

I have a VCDS HEX+CAN for many years and it still works fine on my D2 S8 and my 2008 TTS. But recently, I’ve tried it on a more recent TT and a ‘22 A4. It connects and scans but I don’t get much information and it ...

….. but I suspect that I maybe disappointed!

Another update on this. I recently replaced on of the ‘bellows’ on the intake manifold and, not only has the fault code for the secondary air injection system gone away, so has this judder! The S8 is again running like a dream

Well, my plastic tool that came with the car (and with the TTS) is pretty knackered, so I've replaced it with this: https://www.ebay.co.uk/itm/186948574439.

I can confirm that it fits well and appears to be very well made.

Thanks Paul. Did that part include seals?

I’m wondering if, as I’m replacing the headlight washer pump (plus seals and connector) and the viscous fan coupling/clutch, should I also replace the screen washer pump (and seals and connector) as a precaution? If so, can you gurus let me have part numbers again?

Thanks very much indeed both!
