Audi 2.0L Emmisions failure, MOT Test.

He said scrap out that car...............Uhhh take it to another mechanic!!!

Could be a wiring issue to the Throttle Body Switches or elsewhere. There
might be 2 switches on your throttle body, one for Wide Open Throttle (WOT)
and one to sense when the throttle is closed. I would strongly suspect the
wiring to those switches but emission test results might indicate something
else.

Could be a Coolant Temperature Sensor.
It is probably something very simple and not expensive!

A good book along with a digital Volt Ohm Meter can do wonders!
You might want to post the emission results which may help point you in the
direction of where to look for the problem.

Like Chris said, find someone with the vag-com tool and see if they will
help you.
You can contact people that are close to you on one of these two other
lists.
