Fyodor Dostoevsky
Ready to race!
I've had a 2013 mk6 GTI for two years (second owner).
Since I've had it I've noticed what appears to be detonation (aka: knock, pre-ignition) when the engine is under heavy load from 2000 to 3000 rpm. It sounds something like a rattlesnake or shaking some chains with your hand.
It also seems like the engine makes some adjustments in an attempt to stop the detonation, since the sound reduces in intensity after it first happens (or sometimes disappears entirely), but will then re-appear after a few minutes the next time I put the engine under heavy load again.
I have always used "Top Tier" premium gas - 92 Octane. Once I tried a tank of 94 octane and the detonation was maybe 50% better, but still noticeable.
Also the car has only 17,000 miles on it, so I would think carbon build-up shouldn't be an issue.
So my questions are:
Is detonation typically a problem with the 2.0T engines?
Does the 2.0T have detonation sensors and an ECU algorithm for preventing it?
If the engine is indeed experiencing detonation will there be error codes stored in the ECU indicating this?
