DISA Valve kit
 

how many of you have done DISA valve repair kit (GAS) vs X8R metallic flap version? Do you guys recommend buying new instead of doing the rebuild kit.

Update:
Pulled the DISA out as to prepare it for Tuesday when the kit arrives. I am lucky I tilted the DISA down as i pulled it out because as soon as i got to the work bench and i turned it around the pin fell out. It took me 20min to get the rubber seal out since it was dry and kept breaking, but also whoever took this out in the past used some sort of gasket maker when reinstalling it. Gasket maker was a pain to clean up as well. i'm just glad i caught it in time.

I did it on each of the I6 e53s I have.

I have no regrets. If you want to cover all of your bases you can buy a new DISA from them with the GAS kit installed.

I used the GAS kit on the old 525i and the old 3.0i
If the diaphragm is still working, I would just get the kit instead of the new DISA.

^^:iagree: would rather rebuild my perfectly good part with even better parts for $85 - mine is 2+ years and going strong

Thanks everyone. Parts ordered, should be here by Thursday, knowing my luck, the pin will drop on Wednesday :banghead: so the car is parked until i change it. :-)

I fitted the XR8 Metal flap kit. I had an engine management light on and checked the Disa flap and it was missing. So had to remove the manifold, etc. to make sure the flap & pin was down there. It wasn't, so unsure where it had gone. Fitted the flap and the quality was second to none, with the pin running through the whole flap and not just the top bit.

Also, just so happens the company is only based a few miles away.

Yeah the product looks really well built. I actually ended up getting the regular replacement which was about half the price. i would have definitely bought the XR8 if i was planning to keep the car longer.

The German Auto Solutions DISA valve repair kit is one of thee best upgrades you can do on your M54 engine, IMHO.
The valve was making a 'ticking' noise at idle on my E39 530iT and upon removal was found to be badly worn, with the pivot pin partially migrated.
The GAS kit has well-engineered, high quality parts, clear instructions and is also reasonably priced.
You can do the mod in 30 minutes and you won't lose any more sleep, knowing that the flapper valve pin won't end up inside your engine.

Parts came in today.. Here is the before and after picture.. sorry for the crappy iphone pics...

Does the GAS kit not come with a flush mount titanium bolt anymore and they switched to something with a rounded head up top? Nice work, been a couple years but mine went in a bit different I think.
