Hi mate, car still working like it should with no errors coming on at all, its a relay underneath the ecu, it’s defo 614 if your a6 is a 2007.

From what I remember If you take wiper arms off, then black plastic cover, ecu metal black casing top right, Audi opened that for me so don’t know how they did it, ecu inside, lift up and there are a few relays underneath, just swap the 614 out with 644 from parts shop, still mega thanks to the guy or gal who found this, we salute you!

Thankyou for your swift reply. I'm currently borrowing my Dads 2009 Peugeot 308 SW Sport and I really want to stop driving it. Hopefully I can make tomorrow that day now.

Worked! Just to pay it forward as mentioned if anyone does find this thread again. There is no 614 relay on the diagram the Parts Dept use. They'll not have a clue. Guaranteed it's under the ECU though. Dead easy to remove. Take off the trim running along the cover and then remove the plenum cover. On the passenger side remove max 5 screws all torx bit. Lift the cover and it'll stare you in the face. Really simply op and under 15 min job getting the replacement relay not withstanding.

Attached is the part number for the latest 644 relay needed.
