In the E53 3.0D ,as its vacuum operated,its a simple fix!Just block off the vacuum pipe that opens egr channel from exhaust.No error lights and no more gunk going into the engine.Egr opens up mainly around short town trips and remains closed on highway trips or WOT,so you get more "gunk" into your engine if you just drive mainly around town. On later 3.0D ,if you disconnect the egr system ,it will bring your EML on,so only way if disconnect the egr is to have the EGR map on the cars software disabled.

Part of the discussion has shown that there is no hard and fast rule as to whether the X5 even has these evil devices, or ever has. I have spoken to Indy, BMW and PMW and even had a look at mine. I don't appear to have the flaps at all, no sign of any mechanism attached to the manifold or of the flap units themselves.
Car going in to be checked to confirm actual status. No parts on Realoem either!! For the sake of a few quid it's better than £7k for a new engine. They were primarily for emissions control and the E53 was never made to meet the more stringent regs so it didn't matter. Now it would be very different of course.

swirl flaps
hi
i have seen the damage these can do and its not nice. the last one i did was a 320 compact with 80k on it. swirl flap from number 4 cylinder had fallen off and embedded its self into the piston crown and then continued to smash into the valves and head. after a lot of time cleaning and machining she ran again but cost in excess of £800 and i am told it was very cheap. my own x5 is a december 05 and does not have swirl flaps. i first checked on real oem and confirmed by looking on the manifold. they can be seen quite clearly if they are there but is obviously harder when they are not there as you cant see them so dont know where to look. 22mm is the common size on most i have done. i did remove a set last week from another compact and it was just in time as 3 were loose and about to fall off. hope this helps dave

Dave....do you mean that you can see the rod that opens/closes the swirl flaps on top of the manifold,as i checked for them on mine a while back by removing the engine cover and couldn't see one so presumed that i didn't have them.
Any advise would be appreciated as i was thinking of taking off the manifold to check for certain...but then if i don't need to thats great

yes you can see the flaps and the rod and the vacuum unit when the manifold is on. i think you will be ok as i have not seen any on an x5 but some say they do. have you looked on realoem. put in the last 7 of you vin and it will tell you.
if you are not sure pm me your last 7 of vin and i will check for you.
