DISA repair kit by German Auto Solutions

Maybe I've missed it, but I haven't seen any posts about this kit in the e46 forum and thought I would pass it along.

Here's the link to the thread in the e39 forum -

http://www.bimmerfest.com/forums/sho...auto+solutions

I installed this today and I'm very impressed, the fit and finish is outstanding. While the base gasket on my DISA was more my problem (which is included), having installed this gives me a little more piece of mind.

What comes in the kit-



Installed-

Not sure it's worth it at half the price of a new DISA. There are more things that can fail on the DISA than the flap.

A new one is 200-250. I'm sure there is a way to lower to price too but it's the thing that fails most of the time.

I think it would be worth it if it were $20. FYI thebmwpartstore.com sells new DISAs for $173.

Well, here is what I read on e46fanatics.

Quote:
What everyone needs to understand about the DISA, there are many parts to it that can fail, not just the butterfly shaft.

The $92 fix only addresses one failure mode of the DISA and it does not really do that so well in my opinion.

In addition to the butterfly valve, there is a vacuum actuator that does fail and when it does, guess what, another vacuum leak and the DISA does not perform properly.

There is an electrical solenoid that controls the valve that can fail and leak vacuum as well and will not control the DISA.

I have not seen this, but it is possible the DISA case could crack and leak vacuum as well.

A new DISA is about $175 on line and if you replace it with a new one, chances are you will never need to replace it again as long as you own your car.

If it was me, I would never waste the time or money to partially fix the DISA when the partial fix is about 65-70% the cost of a completely new unit.

Just something to think about while you ponder buying some partial rebuild kit.

Having just replaced the DISA on my X3, I too think its better to just replace the whole thing rather than try and repair it. Heck, mine disintegrated into two pieces upon removal.....

I can't say I really agree. This kit fixes the portion of the unit that is cause for failure 99% of the time.

And it's not just the flap that has been taken into consideration, the plastic bell crank that shears is replaced with aluminum and a screw replaces the unsecured pin that is know to come loose.

Maybe I'm just easily dooped, but I think this is a great solution.

I'm naturally skeptical of unproven aftermarket "improvements" until they've been run, tried, tested, and after several years still performing properly. There are those products which have been so proven (like the Beisan vanos solution). Still, like others have said, I got 100k miles out of my DISA, and that seems to be pretty typical. For under $200 to get a whole brand new unit, versus $90 for an aftermarket flap I have to assemble, I'd rather just replace the whole thing.

Check back with me in another 100k miles, when the flap on my second DISA goes, and if this is still a proven solution at that point, I could see myself going with something like this.

Valid point. I guess I'll play guniea pig for this one.

FWIW -

" The German Auto Solutions - DISA Valve Repair & Upgrade Kit Warranty


•The kit is 100% returnable for a full refund in uninstalled condition for any reason, no questions asked!

•The kit components are guaranteed for life.

•If any other part of your DISA valve fails within 5 years of purchase date, we will credit 100% of your original purchase price toward a brand new OEM DISA valve with the upgrade kit already installed. This warranty includes failure of any DISA component, including the vacuum pot, electric vacuum solenoid and bell crank seal. "

That's a pretty nice warranty.
