I have a 08 V8 with 145k miles
I pulled codes of VCDS:
P0720 - Circuit Malfunction - Tranmission Output Speed Sensor (G195)
P0715 - Circuit Malfunction - Transmission Input Speed Sensor (G182)
I been reading on G195 its under valve body inside the gearbox, never done ATF change on treg.
Seems like both sensors is close to each other, but don't seem like a common issue.
I checked all fuses, no fuses burned, I checked fuses up front in phelm box and fuses next to battery.
Is there a Transmission reset on VCDS ?
Any one with same issue or knowledge please advice, I don't mind replacing sensors but weird both is malfunctioning, as far as I understand both sensors helps the transmission shift based on speed on gears.
I can drive the Treg, it goes in gears but its almost like the gear box shift to early or late, I have not driven the Treg, Much after my girl friend informed me of weird movements.
