Hey guys,
I have a 2013 VW Golf R. Haldex AWD with open differentials front and rear. I put MT-90 in the transmission and rear differential at 30k and am draining it now at 60k. My understanding is that the Haldex AWD has the front diff doing all the work and the rear diff being dragged along and maybe being engaged 1% of the time (in Florida).
The transmission/front diff oil came out rather dark with some of metal flaky shiny when pouring only, but it blends/mixes out quickly. The rear diff oil came out looking brand new. The odd part is that the transmission fluid had a quite a bit less of that strong gear oil smell compared to the rear diff fluid.
I've accepted that my transmission is on borrowed time. Has anyone had experience with a 3rd party extended warranty accepting this as grounds for transmission damage?
The vehicle has a mild groan at 45-60mph at precisely 2000rpm. This is regardless of gear (5th and 6th are the only ones in this rpm window at these speeds), clutch engaged or not, and even in neutral. It's subtle enough that I didn't notice it until the radio was off and the windows up. The shifts are butter smooth, no grinds. Could it be the output shaft bearings making the groan?
Thanks for your feedback and opinions!
