Does CPO cover diesel glow plugs?

I had a look at the BMWCA CPO document. The plan names specific components that are covered. It says all others are specifically excluded. By that definition, glow plugs are not covered. Furthermore, they don't cover wear, only defects in manufacturing. Even if a covered item needs replacing, it depends on why it failed. Was it manufactured wrong back in 2009? Or has it worn since? And if it was manufactured wrong, why did it wait six years to fail?

Doesn't hurt to ask, but it sounds like the dealer already gave you the answer.

Interesting..Id never seen the Canadian version....

Arguably if the thermostat WAS covered and it failed, and led to the Glow Plug failing, that should be covered. But (a) the thermostat isnt listed and (b) they'd have to buy that cause/effect argument.

Also, if a part fails to last the 6 years as it was intended, that is a defect in the mfg or design. The defect is 'failure to be robust'. Taken to an extreme, Mfgs can't design parts that fail in one year, and state "it wasn't a 'manufacturing defect' since it is actually designed to last one year and made it to one year- so not covered under the mfg defect warranty". Well, at least under USA law.
