The brake pads have sensors in them, when the pads get worn down to the sensor the light comes on letting you know its time to replace. this happens well before the pads are completely gone to reduce wear on the rotors. You should have the brakes replaced and the sensor also.

    Check the rotors to see if they are glazed or pitted or grooved (if you take it to a mechanic they will tell you) if they are any of those things then yes replace rotors too.

I have a 2002 BMW 745 Li and the cd changer got jammed after I put 6 new cd's in it. After that, I tried to unjam the cd with a credit card to get the cd out. This did not work, but immediately after that the i drive stopped functioning. The navigation stopped working etc. You can hit "accept" when you first start the car, but you can not go to any screens. The radio, in dash CD, nor any other function on the lcd screen works. Any suggestions on what to try will be appreciated. The air conditioner controls still work (the knobs) on the car and the car drives fine (windows and everything function) just the computer screen isn't working including the voice response

I disconnected the battery to reset everything and no luck. I took out the navigation disk and installed again and no luck. I played with the cd changer trying to get it out "unlock" and no luck

2002 bmw 745i front parking light malfunction warning but no lights are out

It may be an intermittent ground issue. It might also be a freak instance where the burned out segments of a lamp came back together.

It may also be indication of corrosion on bulb contacts, so the bulbs should be pulled out and checked for corrosion and visually inspected for odd looking filaments. Also check the side fender markers.

Are you getting a transmission warning light in the dash? If you get a warning light, you should have someone check the thermistor that reports the transmission temperature to the ECU. If you are not getting a warning light, it is probably time for a transmission rebuild.
A '95 probably has over 200,000 miles on it by now, right? If it has ever been treated roughly, and/or if the fluid has not been replaced every 50k miles or so, the transmission is due for some work.

My 745i has gas and batterty power but it will not start.

The 2002 BMW 745I has a recall when the gas goes under a third of gas it will shut off and not start cause it thinks it has no gas. You can call BMW and they will check if your car is on the recall list and you can get it fixed for free. Or they told me to just take it to the BMW dealership and tell them.

2004 745i needs a new engine. Is it worth paying

WHY do you need a new engine for the car,whats wrong with it as no engine is worth throwing away and a BMW it worth doing it up as even a 318i is worth doing up etc as the body is worth selling if 100%and the engine is worth doing so dont be a mug.
