OK as I see it, starting at the cheapest and working up, I have the following repair options :
1. Try to fix the existing solenoid using the "bodge" mentioned here viewtopic.php?f=5&t=54578
2. Try to find a new solenoid taking care to ensure the new solenoid is the correct one for the pump. i.e. By checking the last 4 digits of the number on the pump. They should be 4012 or 4004 and the appropriate matching solenoid should be fitted.
3. Try to find a whole new pump, pump module and solenoid as one unit.
My mechanic is worried that if he cuts or disconnects the wires to the solenoid, either to replace it, or repair as per the "bodge", he will need to .... re-enter codes for the pump module and engine management modules ? At least that's what I think he said. Remember folks I'm trying to understand what he is telling me as best I can in Serbo Croat. He admits he's not sure if it's necessary but he knows that if it is ... then he can't do it. Good of him to tell me really
More to the point, he thinks the only place where this could be done is Belgrade in Serbia or Zagreb in Croatia. Both quite a drive from here. Of course by then it will be too late as I won't be able to drive the van.
So ... Q1. Is he right? Under what circumstances or at what point through the repair process will I need someone who can programme the module and or the engine management system. Can I remove, repair or replace the solenoid without needing any computer software?
Apologies for being a bit of a dummy here but the reason I ask is because the guy posting the "bodge" thread
admits the solution didn't work for him and he resorted to fitting a new, slightly different pump, pump module and solenoid from another transit. He says he got the replacement pump "virginilised". What does that mean exactly? Is it something to do with resetting identifying codes in the replacement pump module so the engine management recognizes it? I'm guessing I'll only need to do that if I end up replacing the pump & pump module. I'm hoping I will not need it if I'm just replacing the solenoid.
What say you???
