Thanks so much for putting this DIY together and it helped me a whole bunch with my rebuild.
could the DISA cause cold start rough idle?
Thanks!
so the m52 disa valve do not need to be rebuild
what is the proposed of this valve
the operation of the disa is to change the intake runner length. long runner for low end torque and open for short runners at high rpm
Hey Nathan, I used the rebuild kit on my 04 X5 , before I did it I had an issue starting my car almost every time, I'd have to give it gas so it would turn on, but now that I repaired the flap she cracks right away, now did you you're X5 have that same symptom? And also do you think that might be a reason why rpms would drop and the "trans failsafe mode" message would pop up?
Ugh, just pulled mine out and the flap was broken and jammed it. When I finally got it off the pin was missing. I suppose I have to assume its inside. Any suggestions?
Kit Part Number please send
i have a 2001 bmw 525i it runs great had a coil problme change all of them and still it will start missing like it's running on 5 cyl and if i turn it off and back on it will run fine ! any suggestions
im getting all the codes for a disa issue. I pulled mine off and everything on it is tight, works fine…. but the vacuum wont last longer than 2 seconds…. My car starts up like crap, knocking and banging, but once it warms up after 15 seconds its fine. Also if I unplug the MAF it starts up with out an issue at all (not driving it like that, just idling)…. Could the Disa still be the problem? Bad diaphragm? Or should I investigate other issues before spending 150 on a new one?Thanks.
Hows the eBay kit holding up? Do you know which seller it was as well?
How do I go about getting one of the disa kits I have an 03 325i t54
