Dorman 911-900 Engine Intake Manifold Runner Control Valve Compatible with Select BMW Models

While Amazon kept confirming the DISA valve would fit my 2004 X3 3.0 liter-- the Dorman was the only one to actually have the correct OEM connector plug. I kept ordering DISA valves from Amazon -- going up in price each time. The first 6 I orders ranged from $45 to $70 -- Dorman was double that at $145 -- but it actually fit like the original OEM connector plug. The other DISA valves Amazon had -- have a different electrical connector where the 2 inner prongs are smaller and closer spaced-- which won't let the OEM plug connect. There was another DISA valve that had the correct electrical connector plug-- but it's valve was sized for the 2.5 liter engine -- not the 3.0 liter. The 2004-2006 X3 M54 engines were still made in the Germany plant-- perhaps the other DISA valves Amazon offers fit M54 engines from the Spartanburg SC plant.

2001 330i: first of all, my original one was completely broken, had to remove it to find out bc unplugging it while running is not the way to diagnose faulty part. you must remove and inspect it visually. i had misfire at idle and replaced spark plugs, coil pack, both rubber boots, and removed and cleaned throttle body. this disa valve was last thing i checked to see why the heck i still have misfire problems. once i got this item, it was the blue silicone. my car runs pristine perfect now! its worth the $125 to me just to fix my misfire problems. i havent put many miles on it yet to see how long it lasts, but i will most likely replace it with an bmw oem part soon, bc it says 'made in china' right on the viewable side once mounted, this is sacrilegious to bmw enthusiast as myself. cant simple have china on my bmw! but this item works perfect for problem shooting. no more error codes too!

I purchased one of these for my 2004 BMW 300CI, mainly due to decent reviews and the low price. My car has been having trouble with low power at low and high rpm power for over a year and I have been checking a lot of things. I just now (Feb 2016) removed this DISA valve and looked at it. To my total surprise, there is nothing left on the inside. It looks like everything either fell apart or melted into the intake manifold. I don't know what other damage this caused to my engine, but I would definitely NOT recommend this chinese knock off, unless you don't care about your engine. The original OEM valve failed after 9-10 years but it was just a flap failure where it would rotate freely. This unit failed catastrophically probably within one year. ..............Update Feb 16, 2016....................... I took my car to a BMW specialist because my car was still running poorly and I started hearing a rattle from my engine and thought it was most likely a result of the broken DISA valve parts. They confirmed the noise was coming from my intake manifold. Unfortunately they could not see the parts using a scope, so ended up removing the entire intake manifold and retrieved the flap with (at least) a portion of the metal pin that resides on the end of the flap. They said the frame of the valve most likely broke up and went through my engine. The 2nd and 3rd pictures are the part that was retrieved. The cost for the service was over $500. ............... Updated Feb 22, 2016.................................. The car is still not running right as it does not accelerate hard like it should when "pushed" at highway speeds. I took it back to the Mechanic. He found that it is throwing codes 304, 305, and 306 which is a general misfire on bank 2 cylinders. He did some more testing and found that the bank 2 exhaust header is clogged. He believes that some of the plastic parts from the failed Runner valve made it through to the catalytic converter on Bank 2 and clogged it. He measured 20 PSI of back pressure when it should be under 3 psi. A new Catalytic converter on this car is $950 plus labor to install. Stay away from Doorman.

I was unsure when reading the description, but this does fit the 2001 BMW 330ci I own. The build quality seems pretty good, I had nothing to compare it to though because my old DISA valve was so messed up. This fixed some intake leaks in my car along with a ICV and throttle body cleaning, and a new lower intake elbow it is running a lot smoother. The shipping was great, ordered it with one day shipping, and even though they said it would take 3 days it did in fact arrive in a normal one day shipping timeframe. I can't speak to how long it will hold up, I will update the reviews if there are any problems. The fit was good, and car is running well though.

This was a good replacement for my 2001 BMW 330CI. This is a common item to break on the 3.0l engines as well as a few others. Amazon's fitment guide said this wouldn't work with my car, however I crossed reference the model number and found out that it will. I believe the blade on the 3.0l is larger compared to the 2.5l engines.

For the price the quality is not bad. The part did not fit my 2005 325ci. *does not fit 325ci*

This unit was great while it lasted but after 11 months and only 5,000 or so miles it has failed. When I removed the original unit it had 120,000 miles on it... while the o-ring was bad it didn't look NEARLY as bad as the Dorman did when my mechanic pulled it out a few days ago. I couldn't discern a difference in build quality myself but the results speak for themselves. Save yourself the hassle and just get OEM.. you'll need to buy it eventually anyway!

Aftermarket part & not OEM. Build quality looks less ideal, but it works fine so far. It's worth it for the price and value.
