Avantime Engine Knocking

Cylinder heads and ignition timing, huh? I hadn't considered those. When you had the issue, was the knocking constant, or only under load? And did you manage to fix it yourself, or did you end up taking it to a shop?

The knocking was mostly noticeable under load, yeah. I tried messing with it myself, figuring it was just some buildup, but I couldn’t sort it out. Honestly, I ended up throwing in the towel and taking it to a workshop. Best decision I made! They ran some tests and sorted it out properly.

Took the Avantime to the shop as you suggested. Turns out, it was indeed deposits in the combustion chamber, just like I suspected. They cleaned everything up, and she's running smooth as butter now. Cost me about 425€, but worth every penny. Thanks for the advice!

Woah, that sounds rough! I had almost the EXACT same symptoms with my Avantime a while back. Knocking, power loss, the works! Did you try checking your cylinder heads? And what about the ignition timing? I remember playing around with fuel octane too, thinking it might be bad gas, but no luck. Engine knock can be a real pain!
