Does it need to be physically blanked or can the N57 Swirl Flap Delete simply be mapped out?

Good day,

No matter how many postings I read, I still haven't found an answer that really helps.


Error code 23cxxxx something is indicating that my 640d N57 is experiencing swirl flap issues.

The local indy who has helped me in the past has given me a quote of £500 to blank them out, but I'm not happy with the pricing because it looks exorbitant and comes out as a round figure when you're swamped.

In any case, I've been getting around with it in that state since the mistake essentially disables the turbos. Despite using somewhat more juice, it's perfectly functional.

When you apply BimmerLink while you're driving, the problem code disappears and power returns to normal.

Why not just map it out instead of physically blanking it if it can be cleared in this way? Is there anyone who can confirm this? Alternatively, could you please tell me about the going rate?

The mileage is 130k, and it's over 10 years old. I had a good carbon clean and vacuum tubes done approximately 30,000 miles ago, and it has given me a couple of larger bills recently.

Same thing happened to my 640d. I resolved the issue by installing a high-quality, brand-new manifold from Darkside. Even if you were to remove yours and the swirl flaps, the manifold would still be severely seized, and you would still need to code out the actuator if you wanted to fix the problem. If I were you, I'd just swap out the manifold; the whole process took me less than two hours. With the manifold and swirl flaps changed out, there will be no effect on tourque or anything else. Under two hundred pounds was the manifold.
much success

I don't usually go under the hood!

I think the first choice is the best one.

£50.00 in 2020, £90.00 in 2021, 640 D, and that was a decent indyiuse.

Is it possible that they simply planned everything out or that they went blank?

The metal cam-shaped bullet and gaskets that came with the kit were unnecessary, but the stop is all it takes to keep the arm from moving. After they put it together, look up the blank kit on Google.

I had Jason at BWChiptune in London code out the EGR when I had my N47 tuned, which prevented soot and muck from building up in the intake and ensured that the (new) swirl flaps would not have any problems after I replaced them.
