Argh That's usually something slipping, and that is usually the front broken off the front clutch drum.

Assuming you don't fancy a full rebuild, replacing the clutch drum is DIY'able if you're able to get the gearbox out. Its available new from ZF dealers, or you could use a donor gearbox, although that's a risk that it also has a cracked drum. Prestige have a dead one in at the moment I think, although I don't recall what the fault was.

Problem appears to be with 1st gear. Moving off it makes a jolt and switches to 5th. If I manage to manually switch to 2nd before fault occurs it works fine until goes in 1st again.

Any idea what the solenoid current should be? Most are 0.144A but one is 0.742A?

Also strange that fault code says Gear 3 but problem seem to be with 1st.

Unfortunately no time and no facilities to DIY it if the box need to come off, and not worth paying someone else to do it as car when working was worth 1k at most. I did replace clutch and flywheel on A6 on the drive but car was just high enough to disconnect the box not to actually remove it from under car.

Unless it's a solenoid or something else I can DIY from under the car without removing the box I am afraid it will be the end of S8.

As soon as I move off, jolt and fault code registered for gear 3 when it's only been in 1st, if I manage to get to 2nd all other gears work fine including 3rd until it selects 1st again.
