Intake Manifold - Advise / help

[chris851]

Hi All,

I have an 2006 GTI, APR Stage 2+ tune. Dump and full APR exhaust. For the last 3 months I have the below error codes.

Have done Basic settings with VCDS out put tests, unplugged the motor and replugged etc. All run OK. I can see the Intake Manifold motor moving.

Service place said the intake manifold motor is not moving wile the car is driving. It can't work out a fuel base line and one is not set.

My low end performance has declined and fuel usage is down 150 - 250mk a tank.

I think i really have 3 options.

1) APR Intake Manifold delete kit. with labor about $800 - $1000
Can't find any reviews on the kit and if fuel usage would be better or worse then stock. At least with the kit the problem would be gone to never return.

2) Get the service place to look closer into the problem. 120 + an hour labor. And then new parts ect to replace maybe manifold and motor. ($400 - $1000+)

3) Get a new Intake Manifold motor with the same part number have them fit it and run basic settings. Hope it works. About $200 for the part labor on top of that. May not fix the problem.


Any one have some wisdom / had this happen to them or any one with the APR delete kit.

It's a bit too expensive to just throw parts at it hoping for a solution
Getting a VAG shop to look at would be the best approach I think

I take it you've read this on the VCDS site?
*May be the result of a vacumm leak"

Possible Causes
Intake Manifold Runner Control Basic Setting not performed
Wiring from/to Intake Manifold Runner Control faulty
Intake Manifold Runner Control faulty

Possible Solutions
-Perform Intake Manifold Runner Control Basic Setting
-Check/Repair Wiring from/to Intake Manifold Runner Control
-Check/Replace Intake Manifold Runner Control

Special Notes
When found in Engine: 2.0l TFSI, perform Basic Setting. Check TSB 01-08-12 or 2018402 (NAR) North American Region vehicles only. Check Engine Control Module Software Version, if necessary perform Update.
Replace Intake Manifold Runner (V157) with updated part.
Additional information may be found by searching RVU 24M2 / O3 (Exp. date November 30, 2011) or calling the VW dealer and checking the VIN.

When found on Direct Injection engines, such as the 2.0l TFSI, in combination with system too lean or similar faults indicating a vacuum leak diagnose them because "Regulation Deviation " may be the result of a vacuum leak

Thanks for the reply.

Car has been to German Auto (very helpful) who suggested the first two options.

Yea I have seen that. Boost gauge not showing any boost leaks that i can tell. Its been on the Dyno, they said it was running very rich. I think this is because the no fuel baseline the car runs rich to protect its self.

Boost hitting 20psi Drops to 18 on WOT

[chris851]

I have had my CAN software updated to take the RCD 510 don't think that would have interfered

Boost hitting 20psi Drops to 18 on WOT

That looks healthy and is similar to mine - I hit 24psi peaks

Tough call - option 1 for performance or option 3 for low cost
(Option 2 likely to lead to option 3)

sometimes the manifold runners wear giving this issue. .sometimes the manifold motor fails internally...sounds like both..you have deviation fault from runners and electric fault from motor.. ..I would go delete kit.....VDUB..

I would go delete kit.....VDUB..

Do you know of any bad aspects to the delete kit? fuel economy maybe?

Do the manifold apr flap delete and tune. I have installed at least 5 and there all good. If your out of wty it will cost you that much to fix it to original.
