I have one Octavia 1.6 clha.the problem is when is hot and trying to go uphill car looses power accelerator pedal is not responding with very difficulty car rising rpm. Is not limp mode I hane not any dtc and the strange thing is if I let the car for one minute to idle then all are OK without turned off the ignition. I have tried maf sensor fuel pressure regulator sensor which is on the hfp pump, lift pump with ecu, injectors without any result. Can someone help here I am thinking turbo but without any dtc is like playing cards.

Try another scanner. I would check the ecu too.

You think that maybe ecu will be the problem? This that car does is like when you have power uphill you suddenly turn the ignition off but car working with very little power
Also I have read it with vcds and launch

could be cylinder compression problem ?

I would check live data and see IAT when engine looses its power.

Yep could be anything mentioned above but live data is the way to go.

Live data was ok for all above. Actual VS recommended values was almost the same and when this happening (loosing power) again values are equal.i am searching for used ecu to try.

I would open the ECU that you have. A used ECU will have to be adapted to your car. VIN immo and other stuff i think

What is the DPF differential pressure when car is running ok and when not?

CLHA 1.6TDI????
Probably a manipulated software with diag disabled??

Yes clha I have changed the software from another clha with manual transmission because this was dsg and owner put manual on it. The file is with dpf off. This fault is very difficult because when is happening car is like with low fuel to injectors. If I let it at idle 1 minute everything goes back to normal. The key to this fault is temperature when we have more heat this fault is happening more often.

A good thermal imaging camera helps alot with all types of issues

(Example below Here from USA with gasoline vehicles)

Maybe Cat Converter semi clogged... Try to do same test drive with Upstream Oxygen sensor or sensors removed from exhaust. Or temporarily seperate cat convertor from exhaust manifold to test drive... Its going to be a little loud but should only take a couple of minutes to rules out Cat Convertors... If you have a thermal camera then no need to remove anything simply drive vehicle for 5 to 10 minutes and then look at exhaust with thermal camera if temperature before Cat is extremely hot compared to after Cat then you'll know %100 Cat Convertor is not functioning optimally.... Goodluck
