🛠️ 🇩🇪 BMW N55 PCV Valve How to Replace | STEP BY STEP | Easy Way to Fix 28A0 or 101F01

How to replace PCV valve / diaphragm without valve cover removal, what to watch for and what to use.
If your BMW produces whistle noise from engine bay or has rough idle and stall especially during cold starts, or has fault codes 28A0 or 101F01 among the others, that's what you need to check first. In case PCV valve fix wont work, whole valve cover needs to be replaced.

[@johnmichaelkarma]

Isolate the area like a surgeon,nice. Warming the plastic with hot air,great technique. Thanks

[@shanehughes6102]

Apparently you shouldent but the glue / jb weld on the of the circle rim bit as it can glue the pcv valve shut, just put it around the outsides

[@jamesmcknight4146]

Awesome Vid- doing the pCV test as well as swapping it out was perfect and exactly what I needed

[@jonaserrato9707]

So this took out the check engine light out for code p112f?

[@christopersaavalderrama7384]

Hi! Many thanks for the video, i am getting mine replaced soon as it started to make noose only when i come to a stop after accelerating or downshifting. I did the fire test and it seems to be. Will make a video and i will provide feedback

Thanks man great video 👌🏻👌🏻

You’re like a car surgeon. Nice work.

[@bradswan2618]

This was the issue with my 2011 X35. Following this fixed it right up.

[@jcdestroys140]

Have the exact same model, half engine power message sometimes, engine power loss (can feel it when accelerating), lots of air noise, rough idle randomly like it’ll shut off but doesn’t. With the code 28A0. By chance did you have that code?

[@davidjohannson4364]

Thanks for a good video. My 2011 Mini has the same PCV membrane but a cap that is held on with clips. They want you to buy a new valve cover but I will get my cap off and replace it with a new one.

You give me a great help! tks a lot!

[@Amanula20]

I would i have seen your video before i attempt to change my pcv cap on a n53 engine. I destroyed a bit of the gasket cover during removing the cap ! Your solution with the dremel seems good to me.

Did mine and it turned out to be a great fix but only for a couple of hours and now it’s singing like a canary , it’s even worse now , mine was the vanos-bmw one and it sucks ass but going to try the bmwfix one and see what happens, as for this one, it looks like the original diaphragm

[@metropcs5248]

Wow this seems to be a great fix to a bad situation to especially if you can't afford the valve cover at the time,would you consider this a temporary fix or is the Pcv valve replacement still holding up for you down the road awhile. Again thank you for looking out for the little guys

[@MechAdventures]

Thank you, after some time and more research, i would consider this as temporary solution. And replace whole cover when finance allows so.

[@WayneVogeler]

[@battlehrfred]

Hi Great Video Sir. excellent important information on the BMW pcv valve system. 100--100 . i have a issue with my 2013 x5 35i n55 ,3.0 litre Turbo.it has 155 thousand kilometers when it popup a code, 28A0. The top pan gasket was leaking a little on the rear (common issue) so i replace New Top Pan/ valve cover with new gasket, and also installed new spark plugs at same time. the leak was fixed,but still it has popped up the code 28A0. I do hear a 'whistle" from the front seal these past 10 months for a few seconds while i start it up in the mornings only (cold) and also when it is about 2--6 degrees temperature outside,it will whistle.During the summer temperature, there is No whistle from the front seal. the question is that,if i replace this front engine seal,will this prevent the 28A0 code From reappearing?? it really is a nuisance as i have to continue to rest it. BTW I was told it may be the MAP or the MAS Sensor ( i do use a ANCEL BM700 Obd reader for my diagnosis) ty for your thoughts and input

[@MechAdventures]

Hi, no map or mas sensor will whistle or throw code 28A0. Check pcv as per this video and proceed accordingly

[@Matt-xq6ow]

Isn't it better to use something other than JB weld since it's possible it will fail again?

Probably the same to use the silicone

[@dgoldman2846]

@@MechAdventures Ok so I have cut the "cross" up on the cover, removed that plastic material and removed the diaphragm inside. Do I need also to cut and remove the material on the sides, down to the joint seam? This would make the new cap fit on snuggly? I just don't want to cut too much material. Hard to tell in your video, I think it is what you are doing at 3:30 to 3:35?

[@dgoldman2846]

Ok an edit to this message. I figured out what you did, removed the extra bit of plastic down to the joint. Now I put the cap on snuggly. Did NOT glue it in place. Took the car for a 40 mile drive and it seems to be running much better. The check engine light stayed off the whole time also. The only thing is when I stop sometimes I can hear that squealing noise you talk about. I think this is because I haven't glued/sealed the cap on permanently yet. Right??

@@MechAdventures again. Thank you for your response. I am not able to find the required parts for a 2009 325i e90 online. Seems like a mission. Do you have any affiliated links perhaps? Also at the moment , I dont have rough idle or any bad symptoms. The car runs smooth. That said one thing I noticed is. When the car is started and idling. When openeing the oil cap there is pressure release with a hiss sound. So basically close the cap and open again, will result in another hiss. Would this be a good indication of a failing pcv? Or the service guy trying to rip me off. Hard to say.
