what i used to do is pour a small bottle of rubbing alcohol in the gas tank....this mixture burns very hot so it will clean everything out thus burning all the gas particles off......i used to do this in a 1988 mustang gt that ran real rich because of performance parts and i couldnt ever get it to pass the tests....also try o2 sensors as well as possibly map sensor if equipped...this could be the problem....
temp gauge not working? check wiring and also check tempature sending unit and block temperature sensor.

Your dash has what is known in the trade as a dry solder joint in the instrument cluster it will have to be repaired by people whom specialise in this work.
You could try BBA remanufacture as they do a lot of this type of work for us.

Did Audi scan for diagnostic codes? there are codes in the range P0500 - 03 and P0720 - 23 if there is no codes check for a bad wire from the MFI ECM, It is a white/blue wire (B9 on the ECM) to the internment cluster or maybe an other ECM. Hope it may help

Sounds like blown head gasket (or worse) still to me.
Remove oil filler cap and look for grey oil.
Never use water these days but special coolant. Water makes vapour spots and cause block cracks, worse then blown gaskets!!!
vapour does not cool very well.
Look like you have cracks already.
Take a compression test if possible. But might not show op at that temperature.
The gauge indication troubles me.

it is probably a bad solder joint.pull the cluster out and look at the printed circuit board with a lense.there is a bulb that lights up the display as well.
