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

How is the oil pressure ? Worn engines can show "simili-knock" from the rod
bearings, and this is sounding a lot like real knock.

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?

Rick Hayllar
