Updating, towed vehicle last night right around closing time at the dealer , They called me today in the afternoon keeping me updated but unable to diagnose my no start. I told them I just need my fuel pumped changed under the recall, long story short they had 1 pump in stock back in January a customer never picked it up. They installed it and car turned back on picked it up around closing time today ! Did not pay anything hope it can help anyone else thanks a lot guys ! Specially jfoj

Wow, the dealer is unable to diagnose the no start condition!!! I guess this is the case of the foolish techs that hook up the diagnostic computer to the car and it does not tell the tech that there is a failed fuel pump?? Generation Text is an entire generation of kids that cannot think for themselves or solve problems. Fuel pump failures are COMMON on every model and this is old school diagnostics. Either a $4 can of starting fluid and/or checking the fuel pressure with a fuel pressure gauge. For future reference, I often check with the parts department for part availability before I even drop my car off. Sometimes I buck the system and will even order the part before I take my car to the dealer if I know what the problem isl, this way I know when the part gets in, the dealer cannot tell me they do not have parts!!! Glad you are back on the road. This story will start repeating itself over and over as these vehicle get up in miles, however, fuel pump lifespan is more an hour factor. I estimate these fuel pumps are lasting around 5000 hours. Remember that for every second the engine runs, so does the fuel pump. So a City Dweller that sits in a lot of traffic or at stop lights and stop signs may have as many or more hours on the fuel pump at a low mileage as a Highway Warrior that has higher mileage. So you cannot really use mileage to gauge the life expectancy of the fuel pump. Since many of these vehicles have a recall for the fuel pump, I would highly suggest getting it replaced on BMW's dime before you are stranded somewhere.

Hey guys sorry to bother but I thought my nightmare was over , since the fuel pump recall was performed im still now stuck at 1/2 tank and indicator "fuel range" on my display is counting up instead of down varies between 132 and 130 miles this stupid gauge is what made my fuel pump burn out and leave me stranded without gas any ideas? P.s I drove 3 miles home and still stuck at 1/2 tank p.s I read the syphon jet would be the first culprit?

First off the fuel gauge did not cause the fuel pump to fail.
So the question is did you have fuel level problems before the pump failed? It sounds like you did?? You need to search how to use the "Hidden OBC Menu" and it will show you how to see the fuel level in each 1/2 of the fuel tank. http://www.scoopz.com/m5board/E60_Hi...structions.pdf The siphon pumps rarely have problems, usually only if someone has bee screwing around inside the fuel tank. You might remove the rear seat bottom and check the driver/left side sending unit wiring and make sure there is no rodent damage. I am sure if you search you might even be able to find sending unit resistance values. I have seen a few instances where the metal float arm pops out of the plastic sending unit arm causing erratic fuel levels. This usually happens with "new" assemblies where the metal arm pops out of the plastic sending unit arm in shipping. The Hidden OBC Menu will hopefully allow you to see the level in each 1/2 of the fuel tank. I have not watched my E70 closely, but most other BMW's once below 1/2 a tank the drivers/left side starts to drop lower than the passenger/right side of the tank. By 1/4 tank usually the drivers/left side should be empty and stay empty unless there is a hard right turn to slosh fuel over, then it will pump down again quickly. Fuel level senders are also known to have problems as well with restive slider.

As for your fuel range, it doesn't surprise me it went up. Dealership probably had it idling or took it for a short test drive to check out the fuel pump, so any constant speed driving would make the fuel range estimate go up, especially if you took the highway home. |
