But, I just replaced. Do I have a faulty part? Which one is the intake? I'm going to try cleaning it, but I just put the new one's in last week.

intake is closet to inlet manifold

intake is closest to inlet manifold...on the right looking at the engine from front of X3.....also .....are these aftermarket parts ????which brand ?????.....also could be just a bad electrical contact .....so .....ensure the plugs/contacts are clean and wiring good

also .....how did you clear the codes ?????

swap solenoids to see if code follows

you can quickly swap the solenoids and see if the code follows....just like swapping ignition coils on coil on plug systems

Good idea. I'll try that.

Also, I cleared the codes with my OBD. I have a BMW specific one. I only checked because the car started hesitating again.

Try cleaning the Eccentric Valve Sensor with electrical contact cleaner. Oil normally seeps into the connection causing hesitation.

Would this cause a VANOS intake code to be thrown? I just replaced the solenoid again and cleared the codes and it came right back. Do you have a diagram showing where this sensor is located?

a good generic of the eccentric "shaft" sensor

think you meant eccentric "SHAFT" sensor ????

good eccentric shaft sensor image files

If the sensor is bad, it would throw a different code right? I'm getting a intake vanos code.
Also, it would seem that if the sensor as bad, that it would probably make sense to do the valve cover gasket as well. That's a lot of work to do not being sure that the sensor needs cleaning. How can I narrow it down the the sensor if it's not throwing a code? All of this starting occurring with an oil change I did a few months back.

codes are not infallible

you codes and the faults they are supposed to mean are the product of group of human beings who try hard to write the perfect "what's wrong theory" and give it a code exact reason etc

these are far from infallible and can sometimes lead you down the wrong path......so .....you have to use the basic codes/good experience/the fest tribal knowledge and sometimes pure luck


how is your engine running .....what symptoms do you have now.....did you swap the vanos solenoids over and rule out anything ????

since you changed oil ...check this one next

Double check you didn't fall victim to this during the oil change/at some other time

http://www.underhoodservice.com/tech...stored-in-dme/

Service Procedure:

1. Perform all applicable test plans completely for the faults stored. A mechanical restriction or electrical failure of the VANOS solenoid and/or the electrical circuit can cause insufficient oil supply to the VANOS assemblies as well. If the completed test plans results are inconclusive, then proceed to step 2. See Fig. 1.

2. The oil filter cap insert may have been inadvertently removed during the vehicle's last oil service. If this insert is not installed, it will result in non-filtered engine oil being supplied to the engine, thus possibly clogging or damaging the VANOS solenoids.

If the oil filter cap insert is found to be missing, the entire oil filter housing cap must be replaced (refer to the EPC).


Note: Repairs related to step 2 are not considered a defect in materials or workmanship.


oil/filter/pressure in engine and at vanos gotta be good

ok. Here's what happened with the first oil change: The filter insert was not installed as I didn't realize it was part of the cap. I then drove about 350 miles without it and the car ran badly and was shutting off as slow speeds. When I got back home, I realized the filter insert was missing and reinstalled. The car immediately ran better, but still shut off at slow speeds with the airco running. I pulled codes for both vanos and replaced them. Car ran well for about a week before I started hearing whistling sounds and encountering delayed response and occasional rough idle. I pulled a code on the intake on newly installed intake vanos and replaced it and still have the issue. I didn't try switching them. I believe my problem is related to the first oil change I did. The car ran fine prior to that.

maybe time ???

if you sucked dirt in the vanos it may be time to service it

good generic info below

Swamp. Thanks much. Quick question: If I spray some seafoam down the intake, is it possible to dislodge the dirt that might have gotten in there?

try take vanos solenoids off and clean/rebuild pistons etc ????

I can't see how the seafoam would help......but ....you could get a better idea of possible contamination by popping the solenoids out and checking their movement/clean them with carb or brake cleaner....check if one or both are stuck/sticking ????

the amount of possible contamination probably depends on how well the oil changes and other maintenance was taken care of over many moons....you can see from the examples in the previous posts how bad it can get with extended/wrong/not ever done oil changes etc

in your case I would have no hesitation in popping the vanos units out/put new o rings on them and give the setup a good cleanup....you could do the valve cover kit and the vanos service all in one go in a few easy hours and lay many doubts to rest

diy ....air test for vanos

this old one shows the generic method for testing a vanos assembly with simple air pressure......I post it to show how simple these things are but very effective for valve timing/emissions etc



the later bosch direct injection is an even more beaut piece of engineering/computer science.......we used to do a fraction of this with stacked relays on very large direct injection marine recips.....they have improved the craft immensely....read this at bedtime for academic/general education/inspiration !

a bit closer to your vanos

this one shows the double vanos and how simple it is to test ....BUT ....remember you will possibly raise a code if the time to react/travel etc is not enough from the vanos.......the system has to be clean/good piston actuation etc and good electrical signals/electrical connections/computer control inputs

the air might blow any stuck stuff/dirt free ......a bit of a shot in the dark.....I've also seen folks inject cleaners like seafoam into the air stream.....just like cleaning fuel injectors the poboy way

you have to keep in mind that high miles/many moons X's etc have cooked O rings and it's much better to swap them/service the vanos.....be done with the angst about them

the pic below shows a vanos adapter but the price is over the moon ......you can easily piece one together at home on a diy basis

you can also buy a suitable harness as shown below and adapt it for many bmw plugs to test various items from a 12 v power source

VANOS air adaptor links etc

http://www.zpost.com/forums/showthread.php?t=856041

UPDATE!!
Thanks to bignosejim for all the answers.

This fits the BMW Vanos air adapter, and gets you to a 1/4 female NPT:
McMaster 53445K19, European-Shape Hose Coupling.

But it gets better. He didn't stop there.

Get 6534K19 and 4936K153, screw them together, and you have a Vanos air adapter that fits a 1/4 Industrial Shape coupling for less than 12 bucks, instead of 30 bucks plus whatever couplings you may need.

is yours the N52 engine ????....check the oil fill cap vacuum pull

gotta get you to view,study and inwardly digest these tips about another cause for the 2a82 code

keep us posted .....best wishes

Escondido German Auto 5 months ago
+jasoncwchoong If the car is running really rough at idle and shaking, then open the hood and check for excessive vacuum on the oil cap when trying to open it. If it takes quite a bit of force to open it , then your problem is the PCV in the valve cover. If you do not have excessive vacuum and its a code that sets driving down the road then your next step is to reprogram the engine computer with the latest software. Hope that helps clarify some steps to take to resolving your issue Jason
