What do you mean by "going?"

The real story is that there is nothing inherently wrong with the engine if
it
is properly maintained- a lot of people who bought these cars were not
familiar with turbocharged engines and proper warmup/cooldown procedures 
as well as the use of proper synthetic oil at regular intervals. Due to this
lack of maintenance and an insufficient manufacturer's guideline (original
7.5k mile interval on dino oil is ridiculous), there are problems with
sludging 
and resultant engine and turbo problems.

In our old A4, I used M1 0W40 exclusively once the car was out of the
break-in
period. When the head was pulled at about 55k, it was _clean_. No sludge, no
carbon, a very light yellow varnish, that's it. That's with 5k intervals
with M1 
and proper warmup/cooldown procedure, running a chipped ECU pretty much the
whole time.
