I have zero lifetime experience with flex fuel so can't comment on it. I assume it goes bad and clogs up the works just like any other fuel. Am I wrong on this? I see fuel-damaged fuel pumps a number of times over the course of a year. Most motorcycles are toys to their owners. This is even true in the BMW world although it seems to a lessor degree. People buy these things and then just let them sit. And sit. And sit. They lose interest. They get scared. The wife wants nothing to do with it. It has no radio. It has no air conditioning. And, my personal customer-complaint favorites: It's too cold, it's too hot, it's raining.
I say Man Up and ride the darn thing! You just might enjoy it!!We don't know what happened with the pump and from the post, neither did BMW. Their decision was ex cathedra. Now, what seemed to make the biggest difference was the dealer. Bob's is a big dealer and they stood their ground. It worked for that guy.Interesting comments from people that seem not to know what their talking about. Believe it or not folks I'm about to stick up for BMW here so pay attention.
BMW NA, as with all OEM's, has a warranty policy which covers for defects. Not misuse. What's missing in the description of this problem is the cause of the fuel pump failure. Due to the warranty denial I am going to make an assumption. An assumption which may be incorrect but I'm working with a limited set of facts.
The pump presumably needed to be replaced due to gasoline going bad over the course of time. As gasoline varnishes up it literally will begin to destroy the fuel pump. No two fuel pumps will be ruined in the same amount of time due to the variables involved. The OP on the other site conveniently left this out of the conversation completely. If this is the issue there is nothing BMW could have done to prevent the problem. This is not a defect and BMW NA has every right to deny the claim.
The original OP is either unaware of standing gasoline issues or has chosen to ignore them and would prefer to put the blame on BMW. Should BMW teach people about the dangers to vehicle components when a vehicle sits too much? Maybe. If I were an OEM I would certainly bring up common scenarios that tend to cause problems. But having said that this is still not a defect therefore BMW would prefer not to give away their money.
But all of the above is conjecture. Before anyone starts to form conclusions we need to know the facts as they are simply not present. It is far too easy to blame BMW for every little thing that arises.
Please don't write in saying you've never heard of this occurring in such a "short" amount of time. Maybe you haven't. But that doesn't preclude the possibility of it happening. Owners will say many things in order to avoid paying for a repair. People that have been in dealerships for a number of years see many things that occur out of the norm that are not defects.
Long story short: Maybe BMW NA +1, maybe not - we need more facts - we need the causal issue. Until then no one can say including me.
I will try to come up with a picture of a fuel pump where an owner insisted it only sat for one year. If the owner is being truthful you might be quite surprised to see what this pump looks like. And, ethanol makes it worse due to incessant moisture issues.
