325_driver 422 Report post Posted December 11, 2018 Hey all, thinking of doing the DISA on the car Anyone done it via rebuild kit? I see mixed reviews about it Or should i just buy the complete unit Quote Share this post Link to post Share on other sites
eliongater 718 Report post Posted December 11, 2018 I believe the problem with a complete unit is that it'll eventually just have the same problem. I'm considering ordering this kit. https://www.germanautosolutions.com/bmw_solutions/disa_products/m54_m52tu/m54_disa_repair_kit/product_m54_disa_repair_kit.php Quote Share this post Link to post Share on other sites
Olaf 3321 Report post Posted December 12, 2018 (edited) try searching xxxxxxxxxx on ebay. they're out of Sheffield UK, from memory. Seemed like essentially the same kit, and cost less. It's what I did on my e46. Hope that helps. oops i6 Automotive, and they're not so cheap these days, https://www.i6automotive.co.uk/bmw-disa-valve-intake-adjuster-unit-aluminium-repair-kit-3-0-only.html Edited December 12, 2018 by Olaf updated to reflect i6 automotive and link.

Eagle 1662 Report post Posted December 12, 2018 Bought a Rein one from FCP. Currently @ 70,000km and is still ok. If it fails i will just return it as lifetime warranty. Quote Share this post Link to post Share on other sites

The problem is if the stock ones fail they can send broken bits into the engine which is very expensive. The modded ones don't have the same design flaw.

Eagle 1662 Report post Posted December 12, 2018 Indeed. I was thinking failure as in the flap start getting loose\rattles or o-ring leaks when i typed that. Quote Share this post Link to post Share on other sites

325_driver 422 Report post Posted December 12, 2018 Anyone had the actual diaphragm fail on the unit its self? Quote Share this post Link to post Share on other sites
Allanw 1071 Report post Posted December 12, 2018 My old E39 had a failed diaphragm. I think it was from new though - at 115kms when I pulled it apart, it was as tight as new... but didn't actuate ? Personally, I'd just buy a new one - If they first one lasted this long, the replacement probably will too. Quote Share this post Link to post Share on other sites

The metal pin falls out and has sexy time with the valves. 1 1 2 Quote Share this post Link to post Share on other sites
Eagle 1662 Report post Posted December 13, 2018 Yes im aware of the worst case scenario but the pin is far more likely to come out of the valve upon rough removal or poor install. A loose valve flap gives you plenty of auditory warning. Quote Share this post Link to post Share on other sites
