Recommend replacing the fuse (Blower motor resistor) anyway - It's quite common for these to go bad on 5 series Bimmer's, which of course leads to dead batteries.

Before you start looking at the transmission, make sure that your battery is in good shape and the battery terminals are making clean connections. The transmission computer is quite sensitive to voltage variations.
If the problem is in the transmission, the most common failure point that I have read about is the temperature sensor. They sometimes fail after a few years. The sensor is not expensive, and not too difficult to replace, and it was time to change your transmission fluid and filter anyway, right?

This just means that the OBD was reset recently and the car hasnt been driven enough for readings to be given by the OBDII. Just drive the car a while, and then all should be READY. After any OBDII reset, the car must go through a certain number of "Drive Cycles" before the OBDII will emit any readings. Refer to the manufacturer to find out exactly how many, and how to complete them.

Hi rafymoctezum,

The crankshaft sensor for your car is located near the starter. The best way to see it is to remove the driver's side microfilter housing and connected air tube. If you are looking at the starter, the crankshaft sensor is located to the right and is held in place with a 5mm allen bolt.

There is an air bag in the door and it can hurt you.
Disconnect the battery for a while (no one seems to know how long, but several minutes at least) before disconnecting the air bag.
Don't connect the battery and turn on the key to check your repair while the air bag is unplugged or it will set an error code and you will have to take it to a shop to have the SRS system reset so the SRS light will go out.
I expect that the problem is not that the window is not off the track, but rather that the regulator is broken.
I am not familiar with the 5 series, but the window regulator picture in the parts book looks similar but not quite the same as the one used in the 3-series. In the 3 series, the regulator is not difficult to replace, but it is much easier and cheaper to fix the broken one with a couple of zip ties. I fixed the driver side window regulator in my wife's '04 330 with zip ties years ago and it still works fine. I would pull off the door panel and look at it to see if it is fixable in place before ordering a new regulator ($150 on line)

Hi dtkorakbiak,

You will need to remove the passenger microfilter cover under the hood. First remove the filter cover. Then release the tabs holding the delivery tube to the filter housing. The housing lifts up and rotates out out to the side. Under the housing you will find a white plastic cover being held in place with 4 allen bolts. Using a 5mm allen remove the bolts. Once removed, under the cover you will see several control units and fuses and relays. Look for the BROWN relay. That relay is for your wiper/washer system. They do fail after a while. When reassembling the cover. make sure it is seated correctly, if not water can enter the electronics and create problems down the road.

The listed plugs for your car in the NGK catalogue are BK6EQUP. The gap is listed as 0.8 mm (0.31").

This is a guess, as I am not familiar with this particular body, but try pulling up the door sills and pulling the carpet away from the side wall. Are there plastic plugs there? If so, remove the plugs and rig a hose to your vacuum cleaner that will fit through the holes.

There should be a positive connection under the hood that is normally used for jump starting the car. Use jumper cables to power that connection and an engine ground from another car. That will power the car's electronics so you can open the trunk (boot) and replace the battery.

of what?

2001 BMW 5... | Answered on May 18, 2011


This is easily found after you remove the A/C belt. that tensioner is under the car, between the A/C compressor and the crank shaft pulley. after removing that belt you will have to reach up into the motor between the Idler pulley and the power steering pump, it is really hidden well but if you reach up into the motor in that area you should be able ot feel a 3/8 in square hold that you can fit a ratchet into using that tool you should be able to release the tension on the belts*.


*BMW USES VERY TIGHT BELT CLEARANCES AND IT IS OFTEN HELPFUL OT USE AN OLD BELT TO RELEASE THE TENSION AND USING AN OLD 3/8 BOLT AROUND 2" LONG TO HOLD IT INTO THE SLACK POSITION.
