BMW Value Protection Program, look it up. other parts that have lifetime warranty on them are mufflers, starters, alternators, shocks,

and the last time bmw used a plastic impeller was the M52 engines. M52tu/M54 engines come with either Metal or Composite impellers.

out of the hundreds of water pumps ive replaced, the last time i saw an OE one that was plastic was on MY98 and before.

Good points. I guessed most people get confused between composite and plastic since both tend to look somewhat alike.

Does the lifetime warranty applies to the original part that came with the car? Or does it only applies to the replacement OEM part? I would also assumed that the lifetime warranty would only apply to the part that failed, and not the aftermath due to the failing part, right? For example, if the water pump failed and caused engine damage, BMW would only cover the water pump? I don't really see the advantage of the lifetime warranty on parts such as a water pump since most people would replace it as a maintenance item, rather than wait for a catastrophic failure to collect on its warranty.
