On my Fabia 1 I have modified the EGR operation using the following software method, I am now trying to do this on a Fabia 2 but the access code 12233 is not accepted, can anyone confirm if this mod is possible, and also the access code:-

[01 - Engine]

[Login - 11] and enter 12233 as the access code

[Adaptation] and go to block 3.

Give the accelerator pedal a quick "blip" to ensure that the EGR remains turned on for the next minute while you perform the following steps.

Note that the display shows a default adaptation value of 32768 and shows approximately 250 +/- 20 mg/stroke of air intake volume.

If all is well, enter 33768 as the new adaptation value, and select "test". Note that the displayed air intake volume changes, usually to about 370 mg/stroke. The specification limit is 370 mg/stroke, so if you want to remain within OEM shop manual specifications for emission control reasons, you might have to enter a number slightly smaller than 33768. (If you don't care about road-legal NOx emission limits then leave it at 33768. [Depending on the usage cycle, NOx at this setting can be increased by as much as 40%]) If all is well and you have a seting that you are happy with which results in an intake air volume of 370 mg/stroke or just a hair less, enter [save]. The values aren't exactly the same, but when you enter the value 33768, the ECU will automatically adapt it. In my case it was something like 33628. 370mg/stroke is what your looking for.

No it's not possible on pd engines

It is... just not all of them. Depends on the ECU.

I did it on my old PD130 ASZ Cordoba.

It worked on my Mk1 1.4 PD TDI, it is just that the quoted access code of 12233 was not accepted on the Greenline 1.4 PD TDI which has the EDC?17 ECU as oposed to the EDC?15 in the Mk1.

That'll be why then.

Don't think it can be done on the newer ECU.
