I then scanned for codes and found the following:
17988 - Throttle Valve drive bank 1 malfunction
16487 - Mass Air Flow Circuit G70, High input

I cleared the fault codes and still the same result.
I decided to try a throttle body alignment just for
the heck of it, I thought maybe my throttle body was
dead, so I decided to try it, and it worked,
everything returned back to normal.

Heres the procedure, from ross-tech:

This procedure details how to perform a Throttle Body
Alignment (TBA) on many VW/Audi vehicles. This
procedure cycles the motorized throttle body through
various states (idle, part throttle, WOT) to relearn
their positions. Some examples of reasons to perform a
TBA:

The vehicle's battery has been disconnected and
re-connected

The ECU has been removed and reinstalled

The Throttle Body has been cleaned or removed and
reinstalled

The Accelerator Pedal has been removed and reinstalled

In some vehicles, the car will not run correctly, or
may not run at all without performing a TBA after one
of the above operations. The TBA can be performed on
both Drive-By-Wire (DBW or E-gas) as well as
Cable-throttle cars as long as there is no Idle
Stabilization Valve (ISV). If there is an ISV, then
there is no motorized control of the throttle at all.
Typically, '96-'99 VW/Audi have motorized
Cable-throttle, and '00+ VW/Audi have DBW. Obviously,
there are some exceptions. This should be obvious but
TDI's do not have throttle bodies.

There are certain test conditions that must be met
before doing a TBA:

No DTC's in the Engine Controller

Battery voltage at least 11.5 V

Throttle must be at idling position (keep your foot
off the gas pedal)

Throttle body part must not be dirty (carbonized).
Coolant temperature must be between 5 and 95C

Procedure for performing a Throttle Body Alignment on
Cable-Throttle Cars:
These are cars with a physical cable between the
accelerator and the throttle, but WITHOUT an ISV.

Turn the key on but do not start the car.

[Select]
[01 - Engine]
[Measuring Blocks - 08]
Group 098 (Note: use Group 001 for ADY and AEE engine
code)
[Go!]
[Switch to basic settings]
Once you do this you will see the top right display
say ADP RUN. The TB adaptation is being done as soon
as you switch to basic settings. You will see the
values change and hear the TB cycle for the first few
seconds then it will stop. Leave it in Basic Settings
for about 30 seconds.
[Switch to Meas. Blocks] button and you're all set.

Be sure not to touch the accelerator and make sure the
engine is NOT running when you do this!

Don't you just have to wait a few seconds with the ingnition in the "on"
position? ? ?

No, that does not work, the TBA, actually aligns it
with certain voltages and percentages. you can view
this block 141

Any idea how to do a TBA with a Drive By Wire car?

Here is the one for DBW:

Procedure for performing a Throttle Body Alignment on
DBW Cars using KWP-1281:
(Check to see if the engine speaks KWP-1281 by looking
in the top left of the Open Controller Screen Some
examples of KWP-1281 engine controllers are 2000+
Golf/GTI/Jetta/New Beetle/Audit TT 1.8T)

Turn the key on but do not start the car.

Group 060
[Go!]
[Switch to basic settings]
Once you do this you will see the top right display
say ADP RUN. The TB adaptation is being done as soon
as you switch to basic settings. You will see the

Procedure for performing a Throttle Body Alignment on
DBW Cars using KWP-2000:
(Check to see if the engine speaks KWP- 2000 by
looking in the top left of the Open Controller Screen
Some examples of KWP-2000 engine controllers are 2002+
Audi A4, 2002+ VW Passat, and Touareg)

Turn the key on but do not start the car.

[Select]
[01 - Engine]
[Basic Settings - 04]
Group 060
[Go!]
It should say "Basic Settings: OFF" on the top of your
screen.
Click [ON/OFF/Next] to turn on Basic Settings.
It should now say "Basic Settings: ON" on the top of
your screen.
Once you do this you will see the top right display
say ADP RUN. The TB adaptation is being done as soon
as you switched basic settings on. You will see the
values change and hear the TB cycle for the first few
seconds then it will stop. Leave it in Basic Settings
for about 30 seconds.
Click [ON/OFF/Next] to turn off Basic Settings.
It should now say "Basic Settings: OFF" on the top of
your screen
Click the [Done, Go Back] button and you're all set.

Be sure not to touch the accelerator and make sure the
engine is NOT running when you do this!
