[s-cars] S6 pinging woes - the continuation

[Bares, Vittorio]

" I'd also check the fuel system to make sure that you're getting the
proper
amount of fuel actually delivered- if the pump or FPR or injectors are
not
doing their jobs, the computer might think it's sending enough fuel when
it's not."

FPR was replaced
Changed the RS2 injectors w/stock injectors (although used, behavior did
not change - so I assume they are either both good - or both exactly the
same bad, which is unlikely)
I have not done a spray pattern or volume test ...

Additionally, the plugs don't look lean at all - they look rich, very
rich.

I agree that a simple compression test should tell the tale...

So, can anyone post what physically makes the pinging sound?
