DV6C 9HL injector options
#1
I have a 2011 Berlingo Multispace XTR with the 1.6 8v DV6C 115
It has the continental/siemens ECU and injectors.

My last berlingo of the same age needed injectors at a time but it got wrote off before i could investigate further, this one i have now was driving fine until yesterday injector no2 just stopped working. 

The older 1.6 16v engine and the lower powered versions of the 8v dont seem to suffer the same injector issues as this one does. How hard would it be to convert my engine to run the bosch injectors? I could get the injector loom, and change the injectors okay. I assume some form of remappery would be required but i wonder would it work. 

Also how do i test the injectors? I know no2 is the one giving the fault as my OBD scanner says so, and if i unplug it the engine note never changes but i had a read on here:
https://www.berlingoforum.com/thread-21350.html

Just wondering what equipment is needed to read this, and what way do i probe the injector?

Converting to the bosch injectors is likely to be so complex as to not be worth even attempting, as far as I'm aware you would be changing the engine ecu too. And then making that ecu work in your van. And then mapping it to suit a config it's not intended for.

You can get a basic resistance check easy enough with a standard multimeter, somewhere around 200kOhms for the coil is about right. However, just because it checks out electrically doesn't mean it OK, I've replaced 2 recently and both checked out OK on a meter. I didn't get involved in testing them at high voltage, or with an ocilloscope.

If you have the injector out, £20-25 should get it tested properly.

edit,

There was a long-ish thread on here recently on the same topic.

£50 buys a used injector.
£90 buys third-party refurbished one.
£190 buys brand-new one.

I got another injector from the scrapyard into it there this evening, running fine again now.

Just strange how that one went, it was driving perfectly then i went into the shop, got back into it and it threw on the management light and started misfiring.

Good stuff.

They're fitted to a pretty broad range of vehicles so fairly cheap used, not too painful if you can fit and code them yourself.

Back again the berlingo has done the same again this time it was injector no4, P0271

"P0271 Permanent Fault - Injector 4 Control. Short-Circuit Between Two Wires" essentially the same fault injector 2 was doing, the loom is fine so its shorting in the injector.

I bought the berlingo at the start of the month from a mate, and despite asking to give it back he wont take it so it seems i must face the music and fix it myself. 
My mate rather than take the berlingo back has supplied two replacement injectors. 

Speaking to him though it was remapped well over a year ago, i got the details of the remapper who is very suprised that it has done this. He mentions that remapping only extends the duration the injector is held open it does not change the voltage so should not cause it to fail electronically as it has. I messaged HDI tuning as they seem knowledgeable on this and thier advice would concur with the man who remapped it.

So I'm left wondering is the ECU faulty could it be spiking the injectors or something like that causing the solenoids to fail. When the berlingo was driving there between saturday and this morning it was fine. 

However i dont want to just stick another injector in it again, this i feel is time to look into why it failed. 

Any advice of where to go, what to check, who to ask etc would be greatly appreciated.
