TFSI leon no power no boost

[Rodie121]

hey guys just been driving my car last night and gave it some beans and it went really well like normal then after leaving it overnight and driving it in the morning, I was driving steady and then put my foot down to find a huge lack of power almost like the car isn't boosting at all and it is very very gutless.

no elm light has appeared no codes logged

it almost feels like the turbo has been removed from the car it runs smooth on idle and no misfiring. i have notice the exhaust it make a very very slight different note but that may just be me. i have suspicion it may be the air mass flow meter

just wanted to know if anyone had any thoughts

my car is revo'd stage one and i have had the diverter valve change about 1500 miles ago

Diverter valve? Pcv?

 

[Rodie121]

I did think valve but would that go suddenly and surely I would still hear the turbo spool up and what is Pcv

 

[Rodie121]

any more ideas?

 

[LeonCR]

Have you checked the things G has mentioned ?

 

[Rodie121]

not yet but what things am i looking for with a pcv fault

It's the diaphragm at the front of the engine under the cover with the ribbed tube. Check for leaks

 

[Rodie121]

think I've found the problem haha found whole diverter valve to have separated

This has only been on the car for 2 months if that i know there are different revisions but which one should i go for any thoughts?

I have th rev D bud

 

[Rodie121]

No happy, I just chucked the new diverter vavle on and now it's running very lumpy and poor on idle, I went under car to find the exhaust glowing hot near manifold

Turned the engine off and put the old valve back in and still runs like ****

The thing is it ran fine before just lacking power

Thoughts please

 

[LeonCR]

Need to get vag com on it

 

[Rodie121]

Right that was just me being a retard and left a Pcv pipe off, but just road tested it and it goes abit better but no way near I well as before I wonder if the valve is faulty? Are you sure that revision is ok on a k03

 

[LeonCR]

Did you put the new dv valve back on ?

 

[Rodie121]

Yep this is the one I fitted

 

[Rodie121]

Help please guys

 

[manhota]

run vagcom you might have burned a sensor out

 

[Rodie121]

I have a generic diagnostics Kit with live data can't I just use that? So you think that valve is ok for that engine tps said that vavle doesn't match with your car,
