Just circling back on this. Never did get around to installing the defeat harness, still sitting in the garage.
Hello everybody- I bought my golf R with 42,000 and did a apr stage 2+ about 50,000 miles or so, including a stage 2 Black Forest clutch. The shop just diagnosed crank walk and the only thing I could think of that would make it happen is the clutch. Is that reasonable? I’m gutted. The car still has a extended warranty on it that I bought, so I’m going to try my luck. Any advice?
Seems extreme, even if this phenomenon is real to have a new clutch destroy the bearing in 8000 miles.
Not sure exactly when the clutch in mine was installed as previous owner did not get that from original owner, however when he bought it at 32,000 miles the Stg 3 Endo was already installed. I just got my second oil analysis back after my oil change at 63,000 miles. I did an analysis right when I bought it at 51,000 as well to get a baseline and see the state of the engine with the stage 3 turbo and everything came back clean with no wear issues. So at least 31k miles on the clutch and likely more than that.
Emerging trends look very nice, indeed. Metals didn't vary by more than 2 ppm, and the overall
consistency is just what you'd like to find since this oil change interval was similar to the first you sampled.
No wear-related issues stand out. The viscosity is low for 0W/40, but consistent with the first sample so this engine likely just sheared the oil down a bit (harmless). No fuel showed up (the flashpoint is high enough to rule it out) and the oil filter worked well (see low insolubles).
Excellent report for your Golf R.
If simply installing a clutch with high holding power destroyed bearings my car should be showing some serious signs of issues but it isn't.
If you're still around be interested to know what the warranty company said, assume they would deny based on the tune.
