2015 Opel Insignia (aka Buick Regal), same drive train as Saab 9-5 NG (2010-11)
Gen4 Haldex system.
1st drain, 35k Miles, GM OEM fill, 0.35L filled, internal filter changed.
Wear + additives
PQ Index 80
Iron (Fe) 130
Chromium (Cr) Nickel (Ni) 1
Copper (Cu) 246
Tin (Sn) 2
Lead (Pb) 14
Aluminium (Al) 3
Silicon (Si) 8
Sodium (Na) 11
Potassium (K) 2
Boron (B) 138
Molybdenum (Mo) 1
Zinc (Zn) 1095
Magnesium (Mg) 8
Phosphorus (P) 1940
Calcium (Ca) 2512
Lithium (Li) Silver (Ag) Barium (Ba) Manganese (Mn) 8
Titanium (Ti) Vanadium (V) Cadmium (Cd)
Physicals
Water Viscosity @ 40°C 26
Evaluation
Iron, PQ, copper and lead are noted but appear acceptable for the assumed run-in period - viscosity is consistent with Dexron-VI - no previous trend history limits accuracy of the trend methodology however these values appear acceptable.
*** personal note***
The Haldex diff is notorious for breaking in the Opel Insignia scenes in Europe.
Unlike VW, GM did NOT give a service interval for the haldex fluid ('lifetime" fill), so I decided to change it out in my 1st major service, it was a pain to do.... i'll change it every ~30k miles from now on.
the black goo that came out was disgusing.
Ravenol AWD-H was filled instead of GM or Febi Haldex fluid, both are hard to get locally....
