GOOD BYE SWIRL FLAPS!!! - AUDI A5 3.0 TDI QUATTRO PROJECT - DARKSIDE DEVELOPMENTS - PART 7

Prevention is cheaper than the cure...
Although not massively common on these engines, we have seen many swirl flaps get ingested by the engines causing dire consequences.
As we will be pushing this 3.0 TDI engine pretty hard, we thought it would be a good idea to remove the flaps to prevent any possible problems in the future.
To makes things even easier we have put together a full kit (listed below) and annotated this video, so it can also be used as a guide.

So you remove the flaps, and refit with new gaskets, what is the point of the bolts? Do they just block the hole where the actuator fits? Also do you need to map it out?

[@DarksideDevelopments]

Yes, it's just to block that hole up. Some fault codes will need removing afterwards

Maybe a stupid question, but how is it when you make a car, remap, DPF, EGR, flaps and the rest, and how it goes to the MOT, pass the emission test or you just have to find the right garage? I know that it passed before, but how is it now?

[@mb106429]

The MOT emmissions test does not test what the emmissions are when the vehicle is driven. It tests what the emmissions are when the engine is revved a bit parked in the garage. Then they assume that if all the emmissions crap is fitted as from factory and the engine light isn't on then the emmissions will probably be ok when the car is driven. It is a load of bullshit. Based on statistics. To measure the emmissions you need to put the machine in the back of the car and take it for a drive. The fine is for tampering, you could actually get fined and your vehicle being driven around is staying below the emmissions limits. Maaadness

What are the benefits of removing swirl flaps? And downsides? Should i consider EGR delete + swirl flap removal?

No downsides. Less likely to kill your engine. EGR, DPF and Swirl delete should be considered together.

[@mrgrey9584]

@MIKE OXLONG yes you cut it open and smash out the ceramic core, then weld it back up . It’s a labor intensive job on these cars as it’s by the bulk head.. and have to take loads of things off to get the dpf and intake manifolds off . I live in the Isle of Man , so we don’t have MOT inspections If I was you I’d spend the money getting it done, it’s just lots of stuff that’s not needed on your car to go wrong You could just do the dpf delete, and then have the flaps switched off via a map. But it’s better to rip the lot off , dpf gone / flaps gone / actuators motors gone/ then a good remap .

[@Norwegian_Bastard]

Having removed my dpf aswell on a 3.0tdi. best is to just change out the dpf downpipe with one without. Makes for changing the timing chains and tensioners much easier as taking the engine out with the dpf-less downpipe it goes out in 10 minutes. The original downpipe is a cunt and a half to get out. Tok me and a friend 3 hours to get it out. 10 min to get the new in. Had to cut parts of the cars engine at away to get it out, some stupid bracket made it almost impossible and had to cut a good 5x10cm piece out of the car to get it out lol

Would a 2010 VW Touareg tdi have swirl flaps?

[@ottoman180]

Hello,hope you guys can help me out. I have an A4 B7 3.0tdi 233hp. When I cold start it,it goes brilliant. But when I turn the engine off and then start it up again,often there’s a huge loss of power. If I drive for some kilometers,turn the engine off and back on again,often I have full power again. My mate who’s a mechanic thought it was some problems with the swirl flaps or the rods. I ordered new ones,he replaced them but problem stays the same. It seems there not closing/opening properly. My obd2 said codes P0046 and P2008. So not the same code as everyone says (P2015). Do you have any idea what the problem can be? Can I check if there is a problem with the swirl flaps or rods? Thanks in advance.

[@benlowe7089]

I had the same problem, it was the VNT turbo vanes. They can be cleaned.

[@ottoman180]

Ben Martin thanks for your reply. Cleaned with a product like revive for example?

[@benlowe7089]

There's a specific Mr Muscle oven cleaner which attacks carbon that works a treat. It's a tried and tested method. Have a Google for "Mr Muscle turbo cleaning".

[@ottoman180]

Ben Martin great I’ll search for it. Thanks a lot!

[@mj2023uk]

Hi, bit late but the best turbo cleaner imo is forte put it directly in fuel tank . Mr muscle option not as easy and does not go into fuel tank but forte does work and does free up sticky vanes as has saved my wifes a3 turbo diesel.

I have a Q7 4L 3.0 TDI BUG . Is the same process?

[@E69apeTheMatrix420]

I have Phaeton 3.0 TDI and about to do the same thing. I will remove Manifolds and they are bolted / sealed in 2 halfs. you open the plastic manifold like a sandwich and clean inside. I will use isoropyl alcohol after the main bit is scraped out to make it clean as new again. Then use some Wynns gasket maker (or some of your choice) and seal the manifolds up like a sandwich again and bolt back together. I would remove EGR valve on this job 100%! unbolt motor off the valve and then leave the valve in the 100% alcohol for a while and scrub it well clean! Use Mr Muscle oven cleaner (Sodium hydroxide) if you wish. I hope this helps. I havnt done it yet but I am on it now imminently so interested with your progress and tips for the job if you have already started? This video is in super fast forward a little hard to see.

[@vladleonard86]

@@E69apeTheMatrix420 Thank you for the advice. I will keep you updated with the progress. I'm thinking to get ride of the egr and reroute the gases towards the end of the car..maby stick a pipe into the exhaust. Also the DPF... I'm thinking to put a hole in it..or something and then remap. Put an extra HP...but with the flaps off, egr off and dpf off, the engine will be more reliable.

[@E69apeTheMatrix420]

@@vladleonard86 Here in the UK my car would fail its yearly MOT for any of the above however I admire your thinking. I think EGR can be beneficial in keeping the combustion chamber cool as long as they are cleaned after some time. I pulled mine out Sunday and it was pointless, dirty but not blocked at all. The DPF regen works 100% as long as everything else is in order. All the above may be worse than VW out the factory just because all the sensors are entwined like a brain and when you mess around removing stuff the ECU needs a remap to be running good again. Please keep me updated Im interested. The Hex 5mm bolts for the inlet manifold are Ally. Go careful! I rounded 2 of them and they were a pain! M6 x 45mm may upgrade to torx head stainless bolts.

[@chrisdunn6322]

certainly not, its all about emissions

[@PaulBrown-et5ne]

[@owyn768]

They promote in cylinder turbulence at low air flow rates (low boost, low revs etc.) which improves fuel mixing and therefore combustion. Clever things let down in this application with under engineered linkages which were rectified in the next generation engine.

Hi darkside. On pd170 how do you fine tune adjust the exhaust camshaft? Adjusted inlet to 0.01° via the torsion value.

@@DarksideDevelopments thanks for the info, do you not adjust exhaust cam to be at like 6l/hr consumption or something Reason I ask is because after using parts I ordered from you guys to replace every gasket in the car, my fumes/strong burnt oily smell only went after fiddling with the exhaust cam. Wanted to know how I can set it.

The thumbnail? I thought swirl flaps were a thing of the past only BMW and GM used ? My bro bought a 330d a few years ago that "munched it's flaps" It was game over for that engine

[@DarksideDevelopments]

Quite a few 2015 onwards cars use the throttle body and more aggressive head designs to achieve the same effect, which is no good for peak power!
