0,4 boost, first run with the car

[newsh]

. 10-00 - Adaption Level Not Reached.

This is not a code that shows on Ross tech

Can you post a screen shot ?

Or if you're using Vagcom on a laptop you can also save the fault log as a text file

[Lopez90]

Measured mine an hour ago, it's AAN TPS (while doing so, discovered that my throttle cam end is broken ):
throttle closed: 940 ohm
WOT: 2480 ohm

Measured with some random cheapish multimeter and TPS was hot.

And you have no boost issue?

And you have no boost issue?

Everything works as expected, idle TPS is 7.07% WOT is 96.51%, that's why I posted my measurements for your reference. It seems these numbers can vary alot and not cause any issues.

You need to do a proper boost leak test from the MAF hose, should hold 1 bar and drop slowly, you're wasting your time unless you can confirm this.
And then when it can hold noisy check the other things below.

If the N75 is operating correctly, and we know it's ticking on the car so the wiring is ok, then the ECU is not demanding boost (it's in limp mode)

Possibilities

1/
Pull codes again, see if you have an Adaptation fault. Could likely mean an air leak.

2/
It's possible the hose to the map sensor in the ECU is kinked, damaged or disconnected.

3/
There's a boost/vacuum leak you haven't found.

4/
The distributor timing is slightly out, on the 3B this has to be perfect. Check the Zero mark on the flywheel against the marks in the dizzy. The front pulley mark is not accurate. Put the car in gear and roll it forward onto the msrks to take up backlash.

PS of fault code attached.

Gonna buy proper tools for leak testing tomorrow. Have hand vac pump on its way aswell

Did a turbo to throttle body test and it holds preassure. I'm abit confused when it comes to putting pressure from MAF. How slowly will it drop? since the pressure goes out the dipstick.

Where exactly is the inspection hole? I can see the flywheel from under the car, but the inspection hole pictures i find on google isnt like this (attached picture).

Are you following the guide on the boost leak test? Best to block the pcv tube so you don't blow the internal seals in the engine or if not only use low pressure. The dip stick should seal as well.
The timing mark is the top of bell housing window. Look from inside engine bay.

[newsh]

From the MAF hose is fine, PCV pipes should only see vacuum or low pressure but still must be tested. You can go to 1 bar and pressure should drop slowly. If the OCV is all ok you can disconnect it, block the hole and pressurise to 1.5Bar.
If you only test up to the TB you don't test the inlet manifold, injector seals, ISV pipes and all the vacuum pipes including the one to the ECU.

[Lopez90]

Tested from MAF with pcv still connected, about 0,1-0,2 bar. Guess i need to have a look at injector seals

[vidar skotheim]

I have recently heard one guy buy new inlet hose from tradition .. he got only 0.3 bar . The hole for the n75 was not propperly open !!!

[Lopez90]

I wish my problem was "so simple". Just ordered new o-rings for injectors and new injector inserts in aluminium now, hoping it will seal better.

[Lopez90]

New injector inserts and o-rings on injectors. Found a air leak from breather valve aswell, so got a New one. Still no more boost.

I still have air leak from injectors, and after some searching i see others have that aswell, but doesnt seem they have the same issue as mine. Plugges the PVC and put 1bar from MAF. Does it drop too much?

Looks like its ABIT Off? a bit tilted angle on the dizzy picture

[Laaf]

I installed if memory serves me right RS2 o-rings on the injectors back in 2013. As you see in the pictures the Audi ones are a fair bit beefier than the ones supplied with the injectors, Bosch EV14. Only after this I got rid of boost leaks from the injector area.

Yes that's a bit off.
