MK6 diesel pumps, is this correct?

[APH]

Hi, just a curious question, would be interested to know your thoughts,

Mk6 diesel transits, not worried about setting timing or physically replacing pumps, no problem doing that, just the coding bit. Is this correct:

TDCi pump is not coded as just a high pressure pump to commonrail, so straight swap over, and bleed should work ok.

TDDi pump, is coded, however once installed and correctly timed and bled using hand primer, provided that the pump is either brand new (e.g. Never been coded), or refurbed and all codes removed (virginised!), then after fitting you can switch on ignition to position 2 for 60 seconds WITHOUT trying to start the van, wait, turn off ignition and then start van normally. Been told this lets the van ECU "shake hands" with the new pump and it self codes. However if not left long enough before turning ignition off, or if battrey voltage isn't sufficient or pump is already coded then the transfer fails and Van will need to be put on computer.

Is this True??

your thoughts much appreciated, regards,
Andy.

yes your correct tdci dont need coding , looks about right for tddi, not 100% on tddi if you get new pump or recon you normaly get instructions with them, im sure you can have a second hand tddi pump and use your own solonoid to save on recoding, subject has been covered do a search

I would say yes,i would also think if it does fail to code pats light will indicate so

Oh an originally even brand new pumps had to be coded after fitting,they didn`t self learn.(gen. Ford ones at that)

OK cheers, many thanks for the quick replies
