Technical and long: Normal or not: Knock/pinging at full throttle using RON-95?? 850

Hi Henry,

Thanks for replying. Looking forward what Volvo Australia has for ideas.
What kind of petrol have you used? Can you experience (like in my case) a different knock behaviour between between different octane rates?

The whole strange thing is that I expect the ECU to adapt immadiately to gas of lower octane rate, so I don't expect to hear knocking even under extreme conditions (like full throttle in 2nd at 4000-6000 rpm). What you may expect is a power reduction due to ignition retardation, but I claerly HEAR the knocking (short) using the "midgrade" RON-95.

Any experts have a clue?

Regards,

Dutch
