Hi there,

I want to disable my DPF and EGR in my Peugeot 207 CC 1.6 9HZ with 109 HP and EDC16C34. However, I have Galletto and a fixing frame. I bought for testing a second ECU. I want to clone my old ECU and then write it back modified to the second ECU. I do not want to brick my old working ECU.

I already read about the whole stuff but there are still some questions.

I thought to do it like that:

1. Play around with the second ECU. Try to read it and to write it back.
2. Read my old ECU with Galletto in BDM mode.
3. Write the file of my old ECU to the new one.
4. Test whether the car works like before with the new second ECU.
5. If it is fine, reset all counters of the car with DiagBox (additive and DPF).
6. Read again my old ECU.
7. Modify my file
8. Write the modified file to the second ECU.
9. Remove the stuff in the inside of the DPF. Remain all connections. Use a blanking plate for the EGR.


Did I forget something?
How is it on TÜV (car inspection)? I don't think they will see via OBD that the filter was removed, or? They are just looking for errors?
I read that I probably need to disable the additive ECU with DiagBox. Is this true?

Thank you :mrgreen:

Best regards

i think they can not find out that the DPF/FAP filter is removed. they can calculate CO2 emissions and if they are bad (a bad DPF can cause this..) you wont get your TUV. but like u say, maybe they will search with a diagnostic tool for errors in the ECU, but i dont think they will find anything. and if they will, there is the way to delete the errors (i think its called DTC table removing...).
only important thing is to remove the DPF from the car, because your turbocharger can break down.

thats the information i collected few months ago mate.
hope i helped you :)

Thank you for your post.
I asked these questions on many boards but I did not get any helpuful response.
