Flap

Sorry guys another flap question.Seen a lot of posts about taking the flap off the induction box,but can someone give me any idea how to put one back on,do you have to take the box apart and all that.

Yep... U have to take the strut brace off first and then the front half of the CF Air box as the three little bolts screw on from inside of the Air box /the back of the flap. Easy DIY job but be very careful not to scratch the CF box half or loose any bolts inside the engine bay

. Good luck

You don't need to remove either strut brace or CF airbox. Just disconnect the electrical connectors (x3) before manually turning the flap mounting bar to expose the 3 x bolt receptacles. You just need to ensure that you return the bar/flap back to the closed position before re-connecting the electrics - thus not confusing the actuator.

Thanks Rob,just incase i need to put it back on,one of the service guys at bmw says if i ever have any trouble with the engine i may not be coverd under warranty as i have modified it by taking the flap off,and i may need to put it back on in a hurry.

They always tow that same line! What dealership was that at - Ocean Falmouth? The service lads at my old stealers (Yeovil) were pretty cool about my mods and honoured my warranty claims.

Yes at Falmouth,they have always been very good in the past with my warranty claims on my stock m3[and i had quite a few claims] he just had a word in my ear just in case,ive got to know them down there quite well,only thing is i dont think they have seen many CSLs.

U Ruski skunk.

On a more serious note, I originally tried to turn the rod manually with all electrics disconnected and it wasn't as easy as U describe, as there isn't much to grip onto. I thought of putting a small flat screwdriver in the slit where the flap goes but thought ... better not... as I didn't want to brake anything, this being my first DIY fiddle with my CSL. The way I did the job was safe, didn't require any unnecessary force and was quite a bit of fun taking things apart for an up close inspection. I also understand why the air-box is soooooo expensive now

Thanks for your advice Matt,if i cant get it to turn with ease i will try it your way.

What's the point of taking the flap off? Does it make any difference in reality?
