E46 Disa Valve/Flap Repair Kit

[AcidBurn]

Hi Guys,

I plan on either repairing or replacing my Disa Valve on my 330i.

I have two options and i would like your guys opinions regarding these two options so i can make the best choice.

Option 1 = Buy a complete new unit from BMW R2000+
Option 2 = Import a good repair kit from the States for R900 this includes shipping but im not sure about the whole customs thing when it gets here to SA/Cape Town, seeing its a very small and light package im hoping the wont charge me :dunno:

I was leaning obviously towards option two as it resolves the Disa flap problem complete as the new one will also eventually wear out like the old one so its a bit of a no brainer here. However i heard that disa dont only fail at the flap but also at other places.

Please shared some light on this, those who have sufficient knowledge and experience on this unit.

Thanking you in advanced:thumbs:

Shipping will be dependant on the size and weight, customs will depended on the price/value and the type of part and how the guy at customs feels that day.


Just a small technical point though, the M54 (or the other 6 pot e46's) don't have DISA valves, they have a resonance flap, the 4 pots have DISA valves. The difference comes in with the operation, on the 4 pots the DISA valve switches between two different intake paths, on for more toque and the other for more power hence the name DISA = DIfferenzierte SAuganlage (differential intake) On the 6 pots the valve is in the intake plenum and and splits up the 6 intake runners two sets of 3 runners, the flap then opens and closes in certain RPM ranges to use the cylinder back pulses to aid cylinder filling and to create the dynamic effect of a long or short intake by means of resonance waves in the intake.

Personally I would just buy the new one, but that is just me.

I've ordered a German Solutions disa repair kit as preventative maintenance already. Been waiting about 2 weeks so far for it to arrive, customs is usually a 30% charge on the customs manifest value (which the seller sets).

that kit seems a bit over engineered for the problem at hand... have a look for DISA DIYs you can solve it wish some glue assuming the mechanism is not warn badly already... if its warn then buy the kit

UPDATE:

Disa flap fixed today, i quickly stripped it this morning and got cracking on stripping the disa flap mechanism, was a little bit of a struggle but after an 1 hour or so of back and forth tugging i managed to get it out :argh::thumbs:. I then got my high pressure washer and cleaned off all the nasty 'gunk' that was stuck to the flap and disa unit, after drying and some more cleaning with spirits i started to glue everything back together.

I noticed my flap and pin wasnt that badly damaged compared to many i seen on other forum and the interweb.
I bought bostik super glue which i hope will hold for years to come, according to my dad it should be fine as he uses this stuff on jack hammers so yeah.:thumbs:

Assembled everything and decided to let it sit in the sun for a little to dry out any other water and to give the super glue sometime to set. :thumbs:

Then the moment of truth arrived. Installed it and decided since i didnt have a new gasket i used silicone to create a gasket.

and.......

It worked...yeah happiness much, took it for a drive and everything seems cool, nice and quiet no more tappet like sounds:joy::bravo::rollsmile::thumbs:

let the good times roll.:joy:

Haha, I went the other route and bought the repair kit just for the hell of it...

Was very impressed with the workmanship and very thorough instructions - you even get little earbuds and a piece of wire to hold the mechanism while you work on it

Anyway, I now have a cool metal DISA flap and mechanism thats threadlocked into place - it aint breaking any time soon :thumbs:

hi everybody

I know this is an old post but ive also got a 330i and just wanted to ad my 2 cents ,but what I have found in my 330i is a blended DISA valve, and I went in and made my own custom disa valve(had help from a guy I worked with in a steel fabricating business ) , we took n piece of 5mm stainless steel plate and machined it to fit ,but what we didnt expect was that the valve would get stuck if it started to expand becuase of the heat made inside of the engine, but it worked real good for the time it is cold. So to add my word, it is possible to make your own custom DISA valve but make sure to use the right material for the job
