Interesting discussion. I too have 02 Mini Winnie with the V10. I have had to replace one ign. coil which did have a CEL. I lost the Mass Air flow sensor when mice shreded the air filter and the paper bits damaged it. I think a CEL was on for that failure. But lately I have noticed a sound that I assume is pinging. Have tried premium fuel and shock the knock sensor wires under the intake manifold to identify any issues with that. But no CEL. I had fixed the bad HVAC door vac. accumulator failure and thought that would fix the pinging because of the vac. leak causing a lean condition but it didn't. Any one have pinging on their V10. Thank you
