PD100 terrible power

Hey guys, I posted here about that squished hose, so after fixing that and checking some stuff out, the car is still lazy.
It needs much more throttle to go as it used to at low throttle.
Fuel consumption is suprisingly the same despite having to smash the gas more. I cleaned the MAF sensor and it made no difference, neither did unplugging it. Checked all the vacuum lines, the actuator rod moves normally, turbo pushes 16 psi, yet it struggles to go past 120 km/h. Im clueless as to what it could be.

Maybe you got a bad tank of fuel and it has partially plugged your fuel filter?

 

[golf4tdipd]

Thought that too, changed the fuel filter, made a tiiiny differemce, but that was probably because it was about time to change it anyways.

Weak in-tank or tandem pump? Though it's usually some wire or sensor. Check if any codes have been stored (other than MAF).

Alrighty, the only thing I havent done is hooked it up to a scantool, will do and tell you guys.

 

[golf4tdipd]

Oh, I just remembered, could this cause any issues?

 

[Seatman]

Could be the maf, unplugging it should have some effect

I had a no CEL MAF failure on my 2002 Golf TDI and it would not go past 60 mph. Cleaning does not always fix it and X2 on getting VCDS as it will tell you what the MAF is doing and the MAP too.

Unplugging it made barely any difference, but I was wondering if the intercooler could cause any issues if its bent like in the picture I sent.

Looks like the IC could be leaking. Worth checking into.
How did it get banged up like that?

Ran over a deer

Well, I plugged it into a diagnostics tool, only showed the MAF, but that was because I was driving with it unplugged. After resetting the codes nothing showed up. Since unplugging the MAF did nothing, is it dead?

 

[BobnOH]

Best to get underneath and have a look at the IC and all the large pipe connects.

 

[turbovan+tdi]

If the IC has a hole, it will cause it to be sluggish as the MAF readings are off.

Get into your data, put up boos requested vs boost actual and N75 %.

What is your torsion value?

How many miles? Its possible you have a cam going flat as well, or if it has a cat, could be plugged up.
