New 2006 ML 350 owner in London Ontario
No mods planned for my ML350. The used car dealer I bought it from guaranteed that the CEL would be fixed. It is the infamous P0410 fault code for the secondary air pump. It has been back in several times. So far I got a new secondary air pump and relay for it out of the deal. But as I read on the forums it is likely the clogged up air passages so the dealer may be out alot more money if the heads have to come off still!!!! Please find a quick picture attached. My wife, the main driver loves it though, cut through the snow very well yesterday on her trip!!
