Ihave an Audi A4 2.0 TDI 170, it seems to have had the DPF removed before we got it and it has been re-mapped. No.2, -0.36 to -0.60, No.3, +0.07 to -0.40 and No. 4 -0.72 to -0.42. So from a very much amateur perspective, 2,3 and 4 seem kind of similar but 1 is a fair bit higher. This is just me trying to watch the screen and write values 86BMU.
