2006 X5 4.4i Jumping at very low speeds

I have a 2006 x5 4.4i with the 6 speed auto trans. At very low speed, 1st gear < 1000 Rpm the car will jerk back and forth if you are barely giving it gas. Think of it like a person that does not know how to drive a stick shift. This seems to happen more easily when the engine is at operating temperature. I took it to the dealer and they say that there are no fault codes appearing therfore it is normal?? Does onyone have any insight or experience with this issue?

This happend with my 540i (same engine).
Its the motor mounts and/or the trans mounts failing. They allow play in the driveline causing the surges you feel.

I too have a 2006 x5 4.4i with the 6 speed auto trans. At very low speed, 1st gear it jumps once in a while (mostly at cold temp) I think it happens rarely for me to worry about. No codes or tranny issues so far.....knock on wood....

Is there any test or something to look for to see if the engine mounts are failing?

The typical test for engine mounts is to rev the engine up a bit in drive with the brakes on hard and see if there is excessive movement of the engine. Note that if you have never done this and/or do not know what you are doing, watching the engine with the hood open while someone revs the engine in drive with the brakes hard on can be EXTREMELY DANGEROUS. If the person has a bit of experience and has a feel for how much you can rev the engine with the brakes on and not have the vehicle jump, it's a fine test. But woe be the person who asks a friend to do this for him and is watching the engine (from the side of the car over the front fender) and floors it, running into a wall, garage door, or something else in front of the vehicle.

As you can see, I am a bit hesitant to recommend this, not knowing the expertise of people who might try it.

P.S. Plain old visual inspection of the mounts can show gross failures of engine mounts.

Just to be clear... you don't have to rev it up a lot, what you want to do is rev it up every couple of seconds, and then completely let off the throttle, to make the engine twist back and for on the mounts.

P.S. Here's an example of a transverse-mounted engine:





And there are more examples on youtube.

Checked the motor mounts. I do not see anything unusual. The driver side moved up in drive maybe an inch if that. The Passanger side did nothing noticable at all. In reverse the driver side went down about the same distance. passanger side did not move much at all. With no load reving the engine it did not move at all.

I have started running fuel injector cleaner through it thinking that maybe that could be it. Talked to a different dealer and he calaimed that if a fuel injector was partially clogged the computer would pick that up.

Does anyone else see this in an X5 4.4??
To reproduce you barely push down on the gas pedal in drive try to keep it around 700 - 900 rpm and it occurs. once you get over 1k Rpm you have to slow back down and do again.

Typically it would pick it up and throw a check engine/service engine soon light. However, most vehicles do not immediately throw a code for a misfire, unless it is severe, to avoid false alarms. The computer carries it as a "pending code" and only gives a check engine light if it continues and passes a pre-determined threshold. If you have a good OBD-II code reader, or the local AutoZone or other parts place has one, you can see if there are any pending codes that have not yet made a light go on. Many part places will read OBD-II codes for free. If you have it read, be sure to get the exact numeric code, as often rather than giving you the code they'll just say "it says you've got a bad xxx," or "you need to replace xxx."

Unfortunately, the X5 v-8 transmissions are know for having "jerk" problems at start-up, and my guess would be it's a transmission problem, not an engine problem.

Yes my next step is to have them ensure that the latest program is in the transmission. I was wondering if it could be that the transmission is not slipping into first gear properly.

I am thinking about pulling and changing the plugs just to see. I am not one for hanging parts but it is looking like that is what is going to happen.

BTW... BMW corporate called me to discuss this. She verified that the dealerships dont troubleshoot problems unless there is a fault code present. So my guess it must be in a component that is not connected to the computer or the existing program thinks it is in range.
Thank You for all of your input.
Mike

IMola do you use premium gas? I was wondering about the injectors getting clogged and I have been running a really thick concentration of fuel injector cleaner. I am not sure but i think it is getting better. I am going to do it for another tank and i will report back. It has done this since i purchased the car several months ago. I am not sure what the prev owner put in the tank. So i am trying this. Just wondering if you use premium or not.

Same problem

I'm having the same problem with it jumping at slow speeds. It happens when it shifts to 2nd gear it feels like... it's also happening when it is at low temperature... usually when the engine hasn't warmed up yet. When I was researching my car before buying it, I read that 2006 X5's have transmission problems, so I figured that was probably the problem. I'm assuming that whether it is an engine mount or a bad tranny, it will be expensive! Am I right? Thanks!

The dealer had me do an injection cleaning for $160 .... This did not work at all. Does anyone know anything about the stall speed of the torque converter. I am starting to think that it is just the transmission locking in at too low of an rpm.

update... I have been able to get the engine to stuble with out being in gear. A technician looked at it with me and we were able to get the engine to do it for alost a min. He checked the coputer afterwards and there were no codes. So much for the computer picking up any unusual operating conditions!!! This tells me that the computer program is getting inputs that are in range of normal operation. So something it telling it to run at a throttle position that is fluctuating or "jumping" up and down. Since this is drive by wire i am assuming that for the program not to throw an error the intial sensor that is controlled externally is the one sending the fluctuating signal. The dealer would/could not do anything because there was no error code present.
Has anyone had an issue with the gas pedal? I assume that is were the initial sensor is located.

I have the very same symptoms, just started this evening.
I'm nervous to drive the X5--it accelerates even when in Drive, but my foot isn't on the gas

Did any of you find a resolution?
Thanks!

No Resolution as of yet. They have done several tech service bullitens on it. They have also Cleaned the injectors. It has shown an engine code for misfires but they have no clue what is causing it. They have been going through checking the wiring but nothing has fixed it yet. Let me know if anyone figures this out.

I have the same problem when just replacing the transmission oil. Car jumps when using the gear #1 on manual mode or auto mode, and can not even move but reverse only after drive slow speed on the road climbs, and then get moving again after restart the engine. This also causes the engine temperature rises and appears error "Transmission failsafe program". But this never happened when using the manual mode directly gear #2. I think it's because of wrong in changing the oil type but my assumption is there while outside the body of the transmission cable that touched / pull so that the signal is not up to the computer since that time there was a damaged wire wrapping and I replace it with a temporary cover. I'll be back if my assumption correct.

I went to a bmw specialist, he got the transmission program reinitialized. Since that everything works fine. 90$
a month after that I noticed a little leak at the bottom of the transmission, so they changed the wire connection seal. 16$ + 75$
right after I had that Transmission failsafe program code 2x, they cleaned the connector, there was some oil in it. code never came back.

btw, Garage told me not to replace transmission's oil because it can loose particles in it and damage, i did not went in the details...

now my doors are frozen when it goes under -10..

and I still love this car!

Mein Auto: 2006 X5 3.0d
The 06 3.0d has a warm up function in the transmision control program, it makes the vehicle stay in gear longer and feel to rev a little harder before changing up, this is done to bring the transmision up to operating temp sooner, This may be in the 4.4/4.6 also.
When driving it normaly it feels like it jerks into the next gear, this all dissapears when warm/hot.

Thanks for the advice. checking the results of the cable connector no problem, any suggestions to reset the program, but unfortunately BMW dealers away from my house, any other suggestions unplugging the battery and reconnect it, yet I try. Currently the car is getting worse, especially on a cold engine, in case of stepping, the car did not even want to move, and the ramp suddenly into gear # 5 can not be scaled, and can only move slowly on after the engine is restarted.

I just wanted to convey that my transmission problems were over after I unplug the battery and reinstall it. Looks like the computer system reinitialization, I just need to set the date and time and a few settings on the display panel, and all the alarms on the panel dispaly gone. The transmission works very smooth like new when first tried this car. Many thanks for the advice friends so that I could settle all these Things are well. I really love this car! Thank you!

Did anyone ever find a solution to the lurching / jerkiness off the line? I have the same issue in my '06 x5 4.4i. Almost feels like the fuel line is semi-clogged, but the rpm's aren't jumping when the car lurches.
