10 Problems with my M-Class Mercedes W164 that will happen to yours (OM642)

10 Problems with my M-Class Mercedes W164 that will happen to yours (OM642) My new purchase, W164 ML320 CDI in Australia, and here's the top ten headaches that hit. From steering rack leaks fixed with a cheap O-ring, to glow plug drama lighting up the dash, water sneaking in the taillight, sagging headliner nightmare, brittle grille snapping in the sun, faded headlights, dying aux battery throwing warnings, cracked door trim, hail-smash windscreen, and those stupid hood vents breaking off. Full breakdown inside – saves you cash if you're eyeing one of these. Hit like if you've fought these too. Timestamps below!
