Excellent Video with clear steps, very helpful. I like your all other guides which are really good. Thanks Mate

[@GeorgeAusters]

Appreciate it!

[@kentuequi]

Thanks, this is really interesting to know that you can somewhat easily check/change your DISA valves with less hassle (though I think it could be the right time to change all seals and the PCV system in the meantime).

Much better than the BMW doctor who boasts his knowledge of N52 engine. View this, doctor.

[@UCMF4SIJqf75d5wWKVzbTtDg]

cool! it is possible to replace under own home which is nice, thanks, very good video

[@gabrieleloisa7887]

excellent video!!! thank you very much for your help!! i replaced both disas, the voltage regulator, and cleaned the throttle body on my 2008 x5 3.0si using this method. but now I have a code (2A16 DMTL, superfine leak). I must say that the process is not as simple as it seems, but with patience you will have favorable results. With the small disa I found a hose (I think it's from the PCV system heater) that goes between the block and the intake manifold all the way to the alternator. and that makes the job a little risky when it comes to having to pry that hard plastic tube to be able to remove the small disa from the intake manifold. maybe I managed to crack it and that's why now I have that code. (I hope to find a video on how to replace that). At the end, it is not a lie that the work is done in a fraction of the time compared to having to disassemble the entire intake, but since everything has a risk, this is not the exception. Finally, I want to mention that if you disassemble the throttle body, it is not necessary to disconnect it (I did not do it because I didn't know if it had to be reprogrammed, which I do not have how to do). you just need to put it aside safely and out of the way. so there's no risk that the computer won't accept it, or anything that might happen that I don't know about when reinstall it. good luck. and again to george, thanks for your videos, they are very helpful. I mean it.

[@user-vn2hm1ff2h]

You are a master!! tnx excellent video, audio, explanations, shots just perfect

[@GeorgeAusters]

Glad it was helpful!.

[@GrooveDigger808]

This right here is the best idea you've ever had, my friend! Pure genius. Everywhere else insists manifold removal is the only way and I don't ever want to take that thing off again.. The starter motor required it but the problems start when trying to reconnect the last couple of PCV hoses. Suffice to say it had to come off twice to fix the large vacuum leak that resulted from me failing to fully seat the last hose to the crankcase at the PCV end. It was impossible to reach without starting again. Gutted

[@k2akra]

Actually the last crankcase pcv hose is reachable from under the car. Mine was noty fully plugged to the valve cover. With a help of long screwdriver I plugged it in from under the car.

[@GadgetMart]

This worked a treat for me on my Z4 - thanks

[@GeorgeAusters]

Glad to help bud!

[@hhn2002]

awesome video. was trying to get my small disa valve out. got all three bolts, but wouldnt budge, i assumed i must have missed something came here to find out i didn't. yours seems so easy. thanks!

[@GeorgeAusters]

Only 3 screws holding it in, likely just stuck with the gasket, need prising out

[@Gripen85]

Not sure if it works for you but I used a screw driver flat head from the top of the intake and use the intake as leverage. Switch between left and right and eventually it comes loose.

[@1985brob]

Awesome video!!!!! Question, is there an idle control valve on the N52? if so can you show how to change or access it?

[@BryceBrown1]

This has been really helpful thanks, George! I did this with my E61 with the additional stage of removing the cooling fan to gain access to the drive belt as there's very little wiggle room. I'll be replacing my tensioner and belt very soon, too. Similar process as far as access goes. Cheers!

[@Isaac.Reuben]

This was helpful as I’m attempting to replace both DISA’s on my dad’s E60. Cheers 👍 Edit: Just completed the work and your tip helped me alot. Thanks George and Bryce ✌️

@BOOMROCK535I I'm not sure if it'll help you, but I've done an E61 (E60) video on my channel replacing the disa. Similar to George's, but there are some differences.

Both DISA valve videos are excellent! I've just ordered a replacement large disa (Vaico because it was available locally, hope okay 😬) I understand the large disa gets the most use, so more prone to wear compared to the small. Do you concur? My car has done 140,000 km. Keep up the good work, missing the E60! 🙂

[@anthonygillesse7242]

Good video you saved me a lot of time because I would have removed the manifold🇨🇦

[@GeorgeAusters]

No problem man, yeah I noticed that.. Seems like no one else knows this method on youtube!

[@derupierre504]

Hello Georges, Thank you again for this video, I would gladly give a few € but I fear the scam with VISA. My BMW Z4 E89 2009 23Sdrive 2.5l 6 cylinder 200.000Km does not require dismantling the alternator, the small DISA goes through the rear of the engine. There are just a few difficulties with the vacuum hose. The engine was running badly at idle and meows made me think of the belt for a long time, but no, it was the 2 DISAs. Good road to all

[@GeorgeAusters]

Les comparto mi experiencia y solución: Tengo un BMW 530i (E60) con motor n52... Todo comenzó con el clásico chillido que hace el vehículo cuando la válvula pcv está dañada, así lo dejé pensando que era alguna polea, le cambié la banda y la polea loca y el chillido seguía, otro síntoma es que el vehículo de la nada se me apagaba, y comence a notar que el consumo de gasolina no era el óptimo, lo volvía a encender y andaba de nuevo, después hice la prueba con el motor encendido intentaba quitar el tapón del aceite y era tanta la succión que a veces ni siquiera lo podía quitar, lo que me llevó a la conclusión de que la válvula pcv estaba dañada... Después cambie la pcv (en estos motores se cambia la tapa de punterías completa, ya que la pcv viene integrada a la tapa), y asunto arreglado, se quitó el chillido y dejó de apagarse de la nada, hasta aquí todo bien.... Pasó el tiempo y noté que el consumo de gasolina estaba muy elevado y el carro comenzó a hacerme otros síntomas, ralentí inestable, y cuando el motor caía a las 600-700 rpm, el coche comenzaba a vibrar, pero era una vibración excesiva en general, adentro se escuchaba demasiado, el volante, tablero, el habitáculo vibraba mucho y sentí que el carro tenía pérdida de potencia, Check engine encendido con código de falla 2AA9, pero ojo!!, Primero lo escanee con un escáner clásico, actron sencillo y no arrojaba código, hasta que le metí un escáner más completo y con este si lo arrojó, por lo que recomiendo que lo escaneen con el mejor posible... Después quité las 2 válvulas disa y sorpresa!, todo el colector de admisión tenía residuos de aceite, quite el sistema de admision, le hice su limpieza, probé las disa y estaban atascadas, las abrí para checarlas por dentro y que creen?...la disa primaria tenía ya el motor oxidado y con residuos de aceite, le hice su limpieza y volvió a la vida!, pero la secundaria estaba inundada de aceite! Y la tarjeta electrónica que lleva se estropeó, solo pude rescatar la disa primaria, así que preferí comprar las 2 disa usadas en buen estado y originales, que nuevas genéricas... Después hice las pruebas para checar las válvulas, es importante que hagan la prueba de esta manera: coloquen las disa usadas en su lugar pero sin conectar, teniendo las disa nuevas afuera, les puse sus conectores para poder observarlas, eché a andar el vehículo y la primaria cerró por completo y se mantuvo cerrada en ralentí (así debe ser), y la secundaria cerró entre las 3500 y 4500 rpm (así debe ser también), y dependiendo las rpm están abriendo y cerrando todo el tiempo, por lo que concluí que estaban en perfecto estado, ya solo armé todo nuevamente y asunto arreglado, el coche anda perfecto, y ya no tiene ningún síntoma que les mencioné, le borré el código y ya no apareció más.. En conclusión, cuando noten el primer síntoma o que la pcv comienza a dar problemas, no duden en cambiarla inmediatamente!!, esto les evitará problemas con las disa y créanme, les ahorrará bastante tiempo y dinero (disa nuevas, gasto de gasolina innecesaria, sensores, etc)... Si en algo les puedo colaborar, estoy a la orden, saludos!

Thank you. Anything you’d like to see in particular? I have many more videos planned for this engine

[@fradaru1205]

George Austers what I have to do next, but this is very complicated, is to change the seal of the VANOS eccentric shaft (not sure how it’s called in English). I’m this regard I even have to change the valve cover gasket 😅I have so many ideas :) e.g. VANOS solenoid check valve -> very difficult to get there I have to change the hydraulic lifters as well as I have always the ticking which is disappearing with high speed but is always coming whenever I‘m driving short distance And much more :) I love this engine... I want to keep it as long as possible! I also want to try out the clean pistons with Toralin to reduce oil consumption

[@agadamSystem]

Thanks for the video, this seems a lot easier! Do you need to code something after DISA replacement or is it just plug and pray?

[@GeorgeAusters]

Just plug and pray!

[@cw988]

NOOOO..... I just got up to 11:20 on the job, and on the 2008 E92 - N51 I definitely need to remove a CCV pipe that's in the way of pulling the Disa valve out, under the manifold. I can reach the near end to remove it, but not the back end... I'm afraid to try to flex that thing. I could have seen that after removing the alternator, but I didn't look too closely with a light. UPDATE: I got it! Just removed the front end of the pipe, and could push it aside just enough!

[@GeorgeAusters]

Good stuff

Euro N52b30 content in 2020? Nice! Subscribed. I have the same engine in my 330i. If you don’t mind me asking, what year is your car? Mine is 2007 with 87miles. I’m just wondering how soon i should replace the disas. Will definitely diy them after i found your tutorial, you documented the process perfectly.

@@chadriddle3517 Have finally got around to doing this, the video was invaluable. 2AA9 code seems to be gone initially, although too early to be certain. Also, the idle seems better, but again it's early days. Overall not too bad a job. I highly recommend having a tiny 1/4in ratchet (I use one sold as a bicycle tool) as the little Torx bolts aren't the easiest to get at. I did both DISAs, drive belt and air filter and the only casualty was a single snapped plastic clip - I can live with that!

You should not be able to move the flap by hand. You can test the disa if it’s connected to the plug outside the car using inpa software on a laptop connected with cable. You can find it by searching for inpa disa testing probably.
