Was just wondering what use the "Basic Settings" function might be.

What exactly does it do ? I know it can be used for throttle body alignment on petrols, and ABD bleeding, but are there any other uses ?

Anything specific to TDI engines would be interesting.

Couldn't find much info about it on Ross-Tech site.

It came to my attention the other day when I was playing around, and accidentally selected basic settings in the engine module, whilst the engine was running. The idle speed started increasing so I switched off in a panic, and nothing untoward seems to have happened :whistle:
I started wondering what exactly it does.

It sets your car to a higher idle speed and turns off a lot of the "corrections" that are normally done (for example to the injection timing). Other things may happen as well depending on the channel you've got selected. There's a reason that button is in a group that says "Refer to Service Manual!" :-)

the basic settings button does various things... like uwe said, depending on what block your looking at.
eg, instruments it will run thru a test of all the instrument cluster one by one.. (good one to show the mates lol)
central convenience - tests lights, buzzers rear screen demister, wipers etc
abs module - opens abs block for brake bleeding
engine... the boost pressure channel (block 11?) will test the n75 valve or equiv
i found most of this out by messing around... :whistle:

Does the idle return to normal again afterwards ? I haven't noticed any persistent change.
Also, are these "corrections" you refer to, the same thing as people refer to when they talk about adaptation - and will they re-correct over time ?
