    I have asked RT to see if they can add input, but I wasnt under impression it needed coding, just swapout for most cars with a possibility of bleeding.

    Ok had a reply from Dana@RT who is most helpful :) so thanks to RT yet again.

    We didn't use those V6 TDI engines on this side of the pond but providing he/she has the engine PIN these instructions normally apply :

    Immobilizer III Injection Pump Swapping - Ross-Tech Wiki

    If this is the 4F chassis with KESSY module, rather than A4 and 4B chassis A6 models, those instructions may not apply. Ask the OP to either paste the complete scan with VIN in forum or contact us directly with the scan if needed.

    On the B6 audi and every other v6 tdi from 2002 on the pumps are codded so they contain an extra immobiliser which require pin code from the immobiliser in order to make it work. The procedure is fairly involved and the instrument clusters being Bosch rb4 are quite a pain to read the pin from. The immo 3 pin code is encripted which makes it quite difficult to read even with aftermarket tools. I have used few 3rd party immo readers and managed to brick a few clocks in the past ! Thread carefully !

    I have read the Immobilizer III Injection Pump Swapping - Ross-Tech Wiki article, but I cannot understand where the various PINs come from.

    It talks about the IMMO-ID being the second 14-digit string in the extra fireld which I have, but then goes on to talk about 2 PINS one to Login to the ECU coding and one to programme in. Where do these come from?

    Thanks

    You need to read it from the old and new car, the old pump is matched to the old car and as such you need to transfer all the VIN info from the ECU/instrument cluster to the pump EDC module. Where about's are you based ? If not too far from N. London then i could help...
