Probably not the filter, the Fuel Pump is located under the Back Seat.

SOURCE: Own a 2005 BMW M3, car battery draining -battery less than year.

From what you're saying here, I believe that you simply have a bad battery. Most batteries only last 5 years, much less if they're left to sit in storage periodically. You really should charge the battery overnight and do a load test on it the next day. The person(s) you spoke to at BMW were probably sales staff and not actual technicians. Costco has very good batteries at reasonable prices.

SOURCE: ;eft frpmt wheel bearing noise - cost to repair or

if you have more than a 3 year warranty it is covered under warranty
if you are going to do the work yourself you need to remove the front road wheel
find the bolts that hold the caliper on and remove them
remove the caliper leaving the flexible brake line connected or you will have to bleed the brakes when you reconnect it
once the caliper is removed you have to remove the bearing cap in the centre of the rotor
remove the retaining split pin from the stub axle and remove the large nut that holds the wheel bearing
remove the bearings and the rotor, clean all grease off the rotor where the bearings are
use a drift and remove the inner bearing shells from the rotor by hitting them from behind with a hammer and the drift
place the new shells in position and gently tap them into position using a brass drift or a press
regrease the rotor hub with new grease, pack the bearing with grease and replace everthing in reverse order of removal
if you buy the new bearings from a bearing supplier you will save quite a few dollars as automotive spare parts dealers are usually a lot more expensive with their prices
Dont forget to put a new seal in the back of the rotor hub before you place the rotor on the stub axle
the seal can be bought from the bearing supplier as well

Can someone tell me what is going on with my 740 i bmw transmission is heavy and need to give a lot of gas to move it

check the condition of the oil and if it is not bright cherry red then have it changed. Run fault codes to determine if electronic and have a pressure test done to determine if mechanical.. However if it is slow to accelerate then check for low pressure in tyres and that the hand brake is not stuck on

93 bmw 740 does not start usually mornings after it starts first time it will start the rest of day but the following morning it wont start again i think its not getting spark now today it did not start...

I would start by cleaning battery cables top and ESPECIALLY bottoms. I know a pain, but the lower ends are exposed to road grime & grease. Also have your battery "load tested". Between all the electrics and the required voltage to run ignition, they can be a pretty big load on battery. (I have 93 M5 and it has same issues when I store it over the winter months)

Hi when I try to start the car it will try to start but will not stay running for more than a seccond or two. I can also smell fuel like it is flooded. I got a new temp suncor dor the computer but I am...

Hello, My name is Dan. I am not a mechanic. However, I've owned 2 of the same Volvo's. While I don't know right now where the temp sensor is located, I will share a previous experience (cheap repair) of mine. Sometimes, you can get a pin hole or other leak in the hose from the gas cap to the tank. This will cause the fuel smell & to loose pressure in the system. Also, anywhere else along the fuel system is susceptible to leakage. Check wherever there are clamps.

I need to see how the starter is hooked up

Volvo 240/740/760/780/940/960 1990-1998 - Starter

The easiest way to test the performance of the starter is to perform a voltage drop test.
The battery must be in good condition and fully charged prior to performing this test.
  1. Connect a voltmeter between the positive and negative terminals of the battery.
  2. Turn the ignition key to the START position and note the voltage drop on the meter.
  3. If voltage drops below 11.5 volts, there is high resistance in the starting system.
  4. Check for proper connections at the battery and starter.
  5. Check the resistance of the battery cables and replace as necessary.
  6. If all other components in the system are functional, the starter may be faulty.

Many automotive parts stores have starter bench testers available for use by customers. A starter bench test is the most definitive way to determine the condition of your starter.

(see Figures 1, 2, 3 and 4)
  1. Disconnect the negative battery cable at the battery.
  2. Disconnect the leads from the starter motor.
  3. Remove the starter motor retaining bolts.
  4. Remove the starter motor from the vehicle.
To install:
  1. Position the starter motor to the flywheel housing.
  2. Apply locking compound to the bolt threads and install the retaining bolts finger-tight.
  3. Tighten the bolts to approximately 25 ft. lbs. (34 Nm).
  4. Connect the starter motor leads and the negative battery cable.

Fig. 2: ... and remove the starter cables

Fig. 4: ... and remove the starter from the engine

Hope helps with this (remember rated this).

Battery gauge reads low sometimes; will not start

Hello. I realize that you have checked all the connections per your ingition system. To be frank with you, you've checked everything I would have checked. I believe you may have either a dead cell in your battery or a short in it. If I were you, I'd hook-up a relative/friends battery and see if that works before I bought one. Your charging system seems to be alright, and the battery is the only other link in that chain. Let me know, I'll think on it more just in case. Thanks for trusting fixya to help get you going!

Fault test shows no knock enrichment signal from ignition system

Is that the only code? Make sure you check terminal #2 and #6 when checking codes. I don't think the code for knock enrichment should cause the light to come on.
