Rick,

The 7A should not bew pinging when revved and no load - unless you are running something
like diesel fue or real crap gas.  Might be indication of fuel pressure - lack thereof.

There may be something loose that sounds like pinging.  You may want to have assistant
rev. it while you verify noise source.

Does engine run/rev. fine when driving?

Hi Audi Gurus
I believe my 20V (7A) is suffering from pinging.

I can hear it when I rev over about 2500 RPM and when I put my foot down.

I have pulled the codes and I get the all clear 4444.

Can I assume that the knock detector(s) is (are) faulty? From what I have read this is
supposed to be detected as a fault code 2142 or 2144.

I have also read that the computer prevents the engine from being revved if the knock
detectors are faulty. But this does not occur!

Anyone BTDT please?
