Not exactly a fix, but you could just take the flap out. Easy 5 minute job.
Then you will have the induction roar at lower revs without having to turn the sport button on. (Handy of the roads are icy)


Juist read your other thread.
Make sure the sport button is on if you arte trying to watch the flap open, it should open at around 3500rpm then. Otherwise it doesn't open until 5500rpm.

When it is nice and loud and i pull over and check it it is opening and i can easily see it moving , when its not noisy and i check it its deffo not moving. (with sport button on)

Can be a couple of thigs, mine didn't work and eventually needed a new intake case (inc flap) for a couple of hundred quid. Sounds like its an intermitent fault - can only suggest going to your dealer or BMW specialist who have the computers to hook up.

This is a fairly common problem, well, not that common but then as minimal stuff goes wrong with CSL's I guess it is 'CSL common'.
Anyhow BMW replaced a fair few, they may do a goodwill if you're not long out of warranty.

Check the Evo buying guide (should be on the net somewhere) for info about what it is. Oh, mine had it done at 22K

Is that the evo magazine buying guide. ? (The flap is free i checked that).

hi, we have seen this a few times... you'll be amazed at the power difference when you get it fixed! we have probably seen this 5-6 times and every time it has been the flap potentiometer on the right hand side of the intake as you look at it, not that expensive from BMW and only 10 mins to fit, let me know if you need a part number

[api330]

Yes pls mate , Thanks for info

Just take the damn thing out! It's only there for noise reduction so yank it out and never worry about the bloody thing again

[api330]

Have taken it out now ,It sounds spot on.

sorry forgot about this, if you do want it part numbers are...

1363402143 or 13637840383 depends on what year your car is, a dealer will be able to help with which part number you need.
