VW T5 2.5 TDI EDC16U34 174hp NO power after EGR and DPF off

Hello mates,

Last week i deleted the DPF and the EGR in a file of a friend of mine.
The DPF i did by switch and EGR by hysteresis maps.

Now he blanked the EGR and deleted the DPF physically. But now he says that the car feels much slower than before. There is no MIL or something and car runs smooth. But less power than before. Is that possible? And if its possible HOW ?

I attached ori and mod file.

thanks in advance!

try this and if still feels slower then you have some issues with the car or something unplugged/damaged when removing dpf phisically

You are the man!
I got nearly 10 solutions from other users in other forums and noone could do it.

Your file works perfect!

Would you mind telling us what you did?

I see you turned 2nd and 5th Hysteresis off.
Then you cleared some error classes. I think they are all egr related?

Then you set the whole file to zero from 1D2100. What are these Maps for?

Then you set the value next to the DPF switch also to zero. Thats another DPF switch?

And thats it.

Thanks a lot mate !

Hi, I have a similar problem.
I had egr + dpf canceled in a workshop.
since then the car has less power and acceleration is not progressive
can you help me?
I have no original file, only modified egr + dpf off.
thank you very much
