Top 20 2001 BMW 5 Series Questions & Answers

The first thing you need to do is check the engine control module for fault codes through the OBD2 diagnostic port (requires an OBD2 code reader or scanner).

Get BMW Scanner 1.4 cable and software for Windows and read the ABS module trouble codes. That will tell you what the ABS thinks is the problem. https://www.amazon.com/iSaddle-Scanner-Programmer-Diagnostic-Windows/dp/B008RHJTS2/ref=sr_1_3?ie=UTF8&qid=1515358744&sr=8-3&keywords=Bmw+scanner+1.4 It's pretty common for the ABS modules to need rebuilding. They have some tine bonding wires inside thwt break over time from vibrartion and heat. Should cost around $100, check ebay. https://www.ebay.com/itm/BMW-5-7-Series-Bosch-5-7-DSC-0265950006-ABS-Brake-Module-Repair-Service/232536849310?epid=13007981967&hash=item362446bb9e:g:9NAAAOSwUwFZ8K7O&vxp=mtr

Sounds like a thermostat sticking. Some things to do. First check coolant level is up and moving. Second (most likely), change thermostat. Very easy fix for backyard mechanic. Make sure to put thermostat in so water flow is correct direction. Look for arrow on side of thermostat. Next, is belt to water pump loose. Another easy fix in most cars.

Replace the battery. (And possibly the Alternator). Reset any codes and try again. A week battery will cause al kinds of havoc and will result in just what you describe. BMW's are very sensitive to correct voltage.

Absolutely need to pull the codes and see what trouble is afoot before proceeding.

Fuel pump is in the fuel tank.filter is either under the car on frame rail or under the hood.fuse and or relays will be under dash or under the hood.

Hi gina. Their no easy way to check the oil level on these cars. sadly BMW decided not add a dip stick for the easy pull the stick and check it. you have to rely on the oil level sensor, if its low you should get a oil level warning light on your dash. not to be confused with the service light. hope this helps.

Hi, over heating is caused from one of the basic issues. Not listed in a particular order. 1.A leaking or dirty radiator. 2.A def water pump. 3.A faulty thermostat. 4.Elec fans not comming on. 5.def. temp sender. 6.Def.radiator cap. Those are the areas you need investigate. I would start with the radiator, they usually get clogged. Good hunting.

Crash sensor: under the seat under the carpet. Occupancy sensor: under the leather bottom seat.

FRONTS ARE EASY, REAR YOU HAVE TO TAKE THE VERTICAL TRIM OFF, YOU TUBE VIDEO ON HOW TO DO IT. EASY

it was an option (220 code) many do not have either ft or rear.

run the fault codes to find which sensor is failing

If you can hear the fuel pump, it is getting voltage. But the change in it's normal sound/tone that it makes has me more concerned with the pump itself. Sometimes the pump gives you clues that it's about to fail, but not always. The sound change is an indicator something is wrong inside the fuel tank. Have you done a pressure and volume check yet? That's the only sure method to see if the pump is working properly. If you do have a failing pump, I would highly recommend replace the filter too! It's cheap and will save you a lot of headaches if they're done at the same time

Check all your fuses, they come loose and get corroded on these cars often. Give them all a good wiggle to get rid of any oxidation and be sure they aren't blown. If it's not that, check your wiring harnesses.

Check Ur fuses Ur litigate fuse
might b burnt or switch may b bad not making contact

Sounds like the axle gear that leads to the hub along with strut mounts. A bad mount will cause binding and the steering will feel very stiff. In the absence of this your powering steering could be seizing which will affect your steering along with other systems

Radio has a bad wiring somewhere wish makes it not get any signal connection to work

pull cap up at lower end of wiper and tighten with socket
