it's a tddi ....the hi pressure diesel pump ...mounted on the top of the pump is the EDU, also called EDC - this is an electronic module that controls the pump
it is common for these edu / edc modules to fail and bring up the codes you listed
Check wiring first and fuses .
No faults found..then do this to get it repaired.
Put the following phrase's into ebay
PUMP EDC transit
or
PUMP EDU transit
and looks like there is only one vendor left doing it at £89, last time i did this , only two years ago there were lots and as low as £50.
instructions from listing
Remove EDC module from pump without causing damage to the IAT Sensor or Solenoid Wires)
CLEAN the EDC Module (We do not accept soiled modules in for repair, if you send a dirty EDC, it will be returned untested)
Place the EDC in a small Jiffy Bag ONLY (Do NOT send it in old brake pad boxes, clutch repair kit boxes, food storage containers, etc, do NOT wrap it in dirty old rags, towels, blue roll, bubble wrap, or any other rubbish you wish to dispose of, The EDC module is strong and tough, it does not need excess packaging, its unnecessary!
Write your Name, Address, Telephone number and the Vehicle Details which the EDC came off onto a piece of paper, and include it with your EDC when sending into us for repair.

and there is another company ..called ecutesting.com who want you top send the whole pump and be charged over £200
all the best.mark
