Hi Guys, I have a 2014 S7 with a 522155-2 code.
I have access to the fault codes but no service manual. People have said the TISS and TOSS sensors are at the top of the transmission, and that the TISS has 3 wires and the TOSS has 4.
On this machine the TISS has 3 wires and the TOSS has 5. Am I looking at the wrong thing? as at the bottom of the transmission next to the prop shaft there is a similar sensor.
I swapped the 5 wire sensor at the top of the transmission (what i think is the TOSS sensor) today with a used one but am still having the issues.
