Hello, guys, here is the dump from my friend's car. It is a Skoda Octavia 1.6 TDI CR.



He already broke his DPF and emptied it.



He asked me if I can remove DPF in the ecu, and I said I'll try, but I' ve never seen this ecu...



Would someone help me please ?



Here is the dump of the ECU (already unlocked)



ECU part number : 03L906023AG
Engine code is CAYC


Thank you.

Hi, thanks.

Is your file working 100% ?

Thanks.

Already got that one, made with ADS. But I don't if it's reliable...

All right, thank you for the insight.

So how should these 3 parameters be ? Remain untouched (original values) ? Are these modified only for a dpf off ?

Thanks.

Hi, you have 03L906023AG_9979 sw that is after diselgate action. Making dpf of on this sw is total disaster for engine. Make downgrade to sw lower than 9977 and take out plastic insert in MAF. Than I can make you corect dpf off. Your injector will start knocking in the morning in 10.000km with 9977 or higher sw ... if they do not allready.

I hear you, how can I downgrade ?

Hello, thanks. Before flashing I checked for DTCs and we have an EGR fault code https://cartechnology.co.uk/images/smilies/sad.gif

Can you do an EGR off as well please ?

Fault code is : 7343 or P0407 00 [175] EGR sensor 2 - Signal too low

Thanks.

I believe I have same Continental injectors on Megane 3 with start-stop and unfortunately are knocking especially in cold weather. How is that possible that with previous software on Skoda aren't knocking ? They must have changed something related to injectors or EGR ? I'm asking maybe there is a cheap fix to this problem.

Thank you.

You have to start with emptying the catalyst right behind the turbine and then DPF behind the suspension, in the first part you only remove the bottom to the mesh in the second, everything is clean, send the file. If you don't delete it, it won't work.

In PRC2.1 there is one valve which is controlled by a vacuum and you cannot forget about it, that is, you will need to tune the N75 and it is not [connected to the ECU, just a bulb like in a turbine, this is the reason for the loud injection work
