    W211 Om642 Glow Plugs Question

    Had my glow plugs replaced this week for the 1st time in 10 years and 87k. Curious as to why the two remaining good ones (Resistance <1 Ohm) are still look bright and almost as new, where as the dead ones are quite heavily corroded. Is this normal or indicative of some other fault lurking ?
