have you put a different type of power steering fluid?

in some instance, if they put a different type of fluid, the solution bubbles up and makes a whining noise when you use the car.

SOURCE: where do u put transmission fluid in a bmw 740il 2001

Here is the procedure:

The transmission temperature must be between 86° to 130° F (30° to 55° C) before checking With engine running, switch on AC While holding vehicle with brakes, place transmission into each gear briefly With engine running and transmission in park, remove Fill/Check plug. If a small amount of oil runs out, fluid level is correct. If no oil runs out fluid level is low, add fluid as required through Fill/Check plug hole. When level is correct, reinstall Fill/Check plug and tighten to correct torque.

SOURCE: 2001 bmw 740il output speed sensor location

hello ryk786, i/m not a hundred percent certain, but I think the output speed sensor is located at the back of the transmission. With the pan removed, if you look at the valve body and see the EDS valves and connectors, look about 2 inches back toward the end of the case and you should see a connector by itself. There should be a retaining torx bolt and spring holding the sensor in place. After installing the new sensor, do not over-tightend the bolt. The torque should be around 5-6 Nm.

Where is the ignition module located on an BMW 325i 2001?


Failed ignition coils

The ones you replaced may not be the issue

Any coil can fail when it wants to

Have to look at cylinder misfire counts on scan tool,
use a scope,walk new coils,whatever it takes to find the
bad ones

Tip

BMW Oil Service reset for 2001


I did a change today and there were a couple of things I figured out that made it easier. 1. Get a 1/4" drive stubby flex-head ratchet. The one I picked up is about 4 inches long, and it made the job SO much easier! 2. All of the screws and nuts for the cover, the electrical harness retainers and the ignition coils are 10mm. It's the only size socket you need for that part of the job. You will find that having a deep socket and a regular socket is helpful. If the deep socket is a 3/8 drive with a 3/8 to 1/4 drive adapter, that's even better. 3. A standard "small" spark plug socket works fine. You need one with a rubber insert that will hold a plug and not drop it, and that won't come out when you pull it off the back of the plug after installation. 4. You need to have a long extension for the spark plug socket - I used a 9" and a 12" together. Use the "wobble" kind from Craftsman - you can't get a straight shot at any of the plugs, but the angles you need are small. 5. The existing plugs are tight. Use a long handled ratchet or breaker bar on the long extension to crack them loose. They'll unscrew easily after that. 6. Use a torque wrench to tighten the new plugs. 30 N-M is the spec, and if you use BMW spark plugs, the torque is on the box. 7. Do the driver's side first. It's the most challenging (it's not that hard, just tedious) and so you should get it out of the way first. Disassembly instructions: Starting on the driver's side, pop the cabin air filter box off (I won't provide instructions, but it's easy - same process you use to gain access to the brake master cylinder). Rotate the cabin air intake air snorkel toward the engine to make a little more room. Don't remove the snorkel, you don't need to. Undo the two cap nuts that hold the cover on. This will be your first opportunity to use the stubby 1/4 drive ratchet. The rubber bushings around the nuts and the washers are all separate and loose, but they stick together from the heat. Don't drop them when you take it apart. Pull the cover loose from it's gasket and slide it forward and out. Undo the two nuts that hold the wiring harness for the coils. I cracked withm with the stubby ratched and a socket, and then used the 3/8 drive deep socket as a nut-driver to remove the nuts. Using the socket allows you to turn the nuts without the risk of dropping them. Pull the harness away from its studs, and then remove all 8 nuts that hold the coils in place. Again, each one will have a different challenge because of the cramped quarters. I used the stubby ratchet and a socket to crack them, and then used the deep socket as a hand tool to remove them. Once the coils are loose, but still in place, use a screwdriver blade to pop the shiny metal brackets on the coils up. Slip it into the slot below the bracket and twist gently - the brackets lock the connectors, so pull the brackets up as far as they'll come (about 1/2 inch or so) and then gently pull or push the black connector off toward the rear of the car. They're EASY to take apart, so you shouldn't be struggling with them. Starting from the front of the engine (Cylinder 5) undo the connectors and grab the coils under the "ears" that go over the studs, and pull them out - again, you can be gentle because they come out quite easily. I took all four out and set them aside. At this point, you're looking at the four spark plugs deep (really deep - remember the 21 inch extension?) in their openings in the cylinder head. Using the long extension, remove the old plugs and screw in the new ones. Torque to 30 newton meters. This is the easiest part of the job! Once the plugs are changed, put it back together in the reverse order to taking it apart. Install the coils from the back of the engine to the front. The way I did it, I slipped the coil back onto its studs and did up the electrical connection. The push down on the bracket to lock the electrical connection also seats the coil onto the top of the plug. Once all the coils are in and hooked up, put all the nuts back on the coils and tighten them. Then reposition the wiring harness and install the two nuts that hold it in place. With all the wiring, coils and plugs back where they belong, it's time to put the outer cover back on. On the driver's side, but not the passenger's side, you will have to wrestle with the rubber sealing boot where the wiring harness enters the outer cover at the back near the firewall. On the drivers side, the brake lines keep the cover close to the head, and you have to coax the rubber boot, which has a slot in it, to pop into the corresponding opening in the cover. The natural tendency is for the "top" to slip in nicely, and for the bottom to firmly resist going back into place. The trick is to push the top of the boot back and seat the "bottom" and then wiggle the top forward into place. That works! On the passenger side, there's enough room to just pull the cover back and slip it over the boot. No struggling required. Anyway, once you have the boot properly seated in the cover, put the two cover cap nuts back on and tighten them. They bottom, so torque them gently after they stop turning and you're done. Now do the other side. There's more room on the passenger's side, so it goes quicker with less contortions. Total time - 1.5 to 2 hours.

2001 expediction change spark pulgs


The spark plugs are located in the valve covers dwon in wells under the individual ignition coils,(8 of them), the coils have a 2 wire connector going to them, careful unlatch the connector lock and remove the connector male end, then remove the on 8mm machine screw that retains each coil to the valve cover stand off, only do one at a time, twist the coil back and forth to break the bond of the rubber boot to the spark plug insulator and gently pull up while you do this, DO NOT FORCE IT or you will have to replace the coil assembly to get a new boot. The job takes about 2-3 hours.

I have a 2001 bmw 325i it is spurtering like the spark plugs are bad but they are brand new. took it to advance auto they said it has a misfire and the cranksensor is bad..


I only have a couple suggestions. Double, double,double check the ignition wires. More often than not, they will be place in the wrong firing order. If have done that and problem persist, replace all the ignition wires withnew, and double check the wiring order. I'd be interested to know if this is the same symptoms it had prior to you replacing the plugs or after? Good luck

How do you change spark plugs on a 2003 z4 2.5i?


2 pcs gouge caps on engine cover where the word BMW. There is 2.pcs mather are 10mm.nut - you unscrew and remove the cover. Then unlock the fuse as lead cables where the coils are connected, all 6.pcs! Use force and pull out all up from the engine and remove coils. Now you can using 16.mm nut, long extensions and hand ratchets all unscrew! Return everything back then in reverse!
Good luck at work!

How do I change the spark plugs on a BMW 523i engine and what is the correct spark gap?


The spark plug change is very straight forward. Basically, you remove the plastic valve cover trim panel, unplug the harness plugs from each of the ignition coils, remove the two nuts securing each coil, pull the coil up. The rubber spark plug connector boot should come up with the coil. You can now remove the spark plugs.

The spark plugs are not gappable. Install them as they come out of the box.

Replace the rubber connector boots at the same time, these wear out and can cause miss-fire problems.

Note that if you find oil in the spark plug wells, the valve cover gaskets must be replaced. Not only does this make a mess, but it deteriorates the boots and also causes miss-fires.

See the DIY article in the Spring 2005 issue of the Bavarian Autosport - Fast Times newsletter (see link below):

Contact Bavarian Autosport for the spark plugs and connector boots (and valve cover gaskets) at 800-535-2002, or order online.

2001 BMW 740iL is sputtering when I accelarate and shaky when idl


A tune-up and throttle body clean-up is a good idea, but mind you on those cars, the valve covers usually leak into the spark plugs and coils, causing the car to misfire. If you are replacing the plugs and find them soaked in oil; replace your valve cover gaskets or you will be back to the same problem soon after the oil soaks the new plugs back up again.

96 bmw 740il misfire


This is a pretty common problem. I would change your valve cover gaskets. They run around ~ 50 bucks. If they are bad it will leak oil into spark plug well and cause a misfire. Very known on the 740.. Also if tune was not anytime not too long ago id change spark plugs while you at it. Then clear the computer and if you still get misfire on 8 try changing the ignition coil which is right about the cylinder with cylinder ignition coil 5. clear the computer. if you get random misfire and misfire cyclinder 5 after then its your ignition coil. parts store runs around 100 bucks

Change spark plugs


My 2004 Verona had factory installed "NGK BKUR6ETB" regular spark plugs which I replaced at 30,000 miles. The 2005 model year is supposed to have Iridium spark plugs. To replace the spark plugs: 1. Remove plastic top engine cover. 5 nuts 10mm socket. 2. Unplug connector from each ignition coil. qty 6. 3. remove 2 hold down bolts per ignition coil. 10mm socket. 4. remove ignition coil, lifting straight up. 5. Spark plug is now accessible, use deep well 5/8 spark plug socket to remove.
