SOURCE: the engine turns but the car won,t start.

You will need to check for fuel pressure or dirty filter. If you do not have fuel pressure; be sure to check fuses or any relay pertaining to fuel pump (if electric). If fuses and relays are good check or replace fuel filter. If the fuel pump is mechanical disregard fuses & relays and check or replace fuel filter. If this does not resolve the problem then the problem could be the fuel pump if mechanical, If its an electric fuel pump it could be a fuel pressure regulator, fuel pump, crimped fuel line or other wiring issue.

These are the most common things I run across, oh, a crimped fuel line can cause the problem in either case electric or mechanical. Hope this helps in some way, been awhile sense I worked with an older car.

SOURCE: bmw 3 series idle problem

Its most likely a timing problem. unfortunatly this can only be done by a computer! So bring it to a dealership or somene in the know with a diagnostic machine.

SOURCE: unable to upload phone numbers from my Verizon LG phone to my BMW 535i

I apologise if this isnt much help, however this is a common query from customers. They're able to pair the phone to the car but not the phonebook or its other functions.

In most cases this is just simply due to the compatability issues between the system integrated into the car and its ability to fully synchronize with the phone. Its not a problem with the car and visa versa its just that particular phone is too sophisticated/complex for the software to handle.

The only way to see which phones are fully compatible is at your local bmw dealer. They should be able to show you a table of which phones are compatible for your model/year and system it operates on.

Hopes this helps!

SOURCE: Car starts then immediately idles down and shuts off

i have had the same problem at times. my car would start and then shut off. but i found that i needed oil and check my oil and it was a quater low put in some oil and everything went fine i notices that everytime the oil is low the same thing happens also depending on the position of the car being park meaning that if you are in a down hill position or up hill position i will do the same. so you have to accelarate for 1 minute to have the oil go up. i hope this works

How do I replace the battery in my 2008 bmw 535i

It is very easy to replace the battery. It is located in the trunk.
however, you would have to take your car to BMW to reset the car since you have put a new battery in the vehicle.

Bmw 318i wan start after replacing fuel pump

sounds like a electrical problem, if you turn the key to the on position have a friend open the gas cap & listen to sound like a hum when you turn the key to on position if not then you should look for a bad fuse or a bad electrical connection.

It sounds like either the throttle position sensor or the mass airflow sensor are bad-the TPS can be checked with a digital meter, it should give different voltage readings as the throttle is opened with the engine off, key on. The MAF can be cleaned with MAF cleaner, or will need to be replaced. Another, although less likely possibility is a clogged fuel filter.

I have the same make and model. I have the noise on the driver side and it's the blinker. It comes apart for some reason and it's not visible to the naked eye, I'm having it replaced next week. Also, there is a problem w/ this series that will cause your car not to start in the morning. BMW is aware of this problem, but haven't informed any of us that paid $60,000 for this model. I suggest you talk to your local dealer, and perhaps buy a Mercedes next time! Hope this helps.
