Throttle body alignment issues

I'm just wondering if anyone can help with my problem.

I bought an agu engined A3 about a month ago and it has a throttle body error but no MIL light. The idle is quite high at around 1250rpm when warm.

the fault code is p1559 throttle body (j338) fault in basic settings. I did an adaptation and it came up with the last fault and a new one which is p1565 throttle actuator (j338) lower stop not reached.

At this point I fitted a second hand throttle body and did the adaptation again which resulted in the same codes being displayed. The lower stop code does go away with driving but the original code stays.

When doing the adaptation with vcds the first field (valve voltage 0-5v) in group 098 shows ERROR.

Does anyone have any advice on what could be causing these codes?

Also I tried to do and auto scan but it stops during it and doesn't complete, this is all I can get from it.

Thanks for the reply. Today I shorted the battery cables (again) and then sprayed some carb cleaner in the multiplug of the throttle body which left me with the "lost basic settings" error but the adaptation completed and the error is now gone! I'm assuming dirty contacts were the issue.

I've done roughly 100 miles and after 50 miles the error hadn't returned but I've not checked again yet. Mpg and mid range torque have been improved a lot but the idle is still high (1000rpm) and the car cut out on me when I was parking it once.

I'm not sure if it needs more time driving or if the fault has returned causing the stall. It's progress at least!
