Hi,

I need EGR off file for VAG 2.0 TDI EDC17CP14 ECU. Egr is faulty so need also to disconnect it and kil 3 related DTCs:
P0405
P1440
P0403

I changed hysteresis to zero on these adresses but not OK, sometimes engine starts shaking.
1BC672
1BC6CA
1BC784
1BC7D8

Original file is patched with KTAG so I can flash it via OBD with KESS.

You'll have DPF problems after EGR off, very frequent regenerations, especially in urban driving.

... and DPF can be switched off with amending Long Coding for that ECU, I think.

I tried with chli1976 (http://www.digital-kaos.co.uk/forums/member.php/57721-chli1976) advice, zeroing 3rd and 6th hysteresis for EGR. Egr is closed but DTC adresses not OK, with disconected EGR still have P0405 DTC.
hid3 (http://www.digital-kaos.co.uk/forums/member.php/477627-hid3) switching DPF via long coding you think with ODIS or VCDS?
tango (http://www.digital-kaos.co.uk/forums/member.php/4990-tango) thank you for your file but I still have DPF on car so dont need dpf off file.

Yes, via long coding. ODIS, VCDS or any other tool will work which is able to manipulate the ECU coding.
