Hi Todd. I agree that there is something wrong with the motor. To do a tear down is on my dime, so with a 6 yr/160,000 VW extended warranty, I'll wait to do that. VW Reps say they won't touch it until something fails. So, I'll have to wait.
The engine appears to run fine. Performance is great, mileage is as good as ever. I'm sure my NOx is doing fine
Oil consumption is within reality, but seems to be increasing slightly. There's no funny noises coming from the engine.
I do disagree, however, that this engine is wearing due to potential hydrolock. My oil analysis PRIOR to this situation already had high metal counts, so I am discounting that theory. To clarify, the engine never did hydrolock. I was able to start it after three tries or so. But, again, this occurred after my oil analysis that previously showed higher metal counts
Do you have the intercooler anti-freeze kit installed in your car? We've had mild winters since the kit was installed, so I really don't know if it works or not.
