407 2.0 HDI Fuel Injector problem

Good afternoon all,

Yesterday, while returning from work, I broke down on the duel carriage way with no warning. Following a 7 hour wait for recovery, the attending mechanic diagnosed my Pug with a bad number 4 fuel injector.

Today, I attempted to resolve this, however after searching for the part online, I have been unsuccessful at finding the part. I have called Euro Car Parts, however they informed me that they have no parts in the company.

I managed to find plenty of fuel injectors that state that they fit my vehicle, however none of them show the same part number (9660334880).

Does anyone have any ideas? Did they change the part number?

I'm really struggling here and I'm desperate to get the car back on the road.

Thanks for any help.

Yeah, thanks for that.

I plan on checking the resistance of the injectors tomorrow when I bring my tester back from work. I'll also try and check the wiring, however without a test lamp, I may struggle.

Would you suggest clearing the codes and then changing the injector locations?

Well this is a pain in the backside!

Today I managed to get my hands on a new injector and all the kit yo do the swap-out, only to find that after turning the car on, for the first time this week, it runs perfectly. I have done nothing to the car, bar clearing the codes.

🤬🤬🤬

Back to the same old problems!!

Today, having travelled almost 200 miles since Friday, I encountered the same problem once again. I had a sudden loss of power, rough idle and engine management light.

Somewhat lucky, I had an OBD2 scanner in the car and I managed to delete the fault code. This seemed to resolve the issue, however about 2 miles later, the issue arose again.

I called the RAC, however their estimated recovery time was 4 hours and as I was only a couple of miles from home, I decided to delete the fault code again. Again, this seemed to work however just as I was pulling onto my drive, it happened yet again.

My only question is, does this signify that I do indeed have a faulty injector, or not?

Okay, so this evening I swapped out the fuel injector.

Pretty straightforward job in all honesty, bit fiddly getting the fuel return clip back in, but otherwise it seemed to go okay.

As I said before, when I did my resistance measurement last week, everything seemed to be okay. Upon removing the offending injector however, I have noticed a crack on the body of the injector.

Anyone have any thoughts?

Could this be the culprit? I won't know for sure if the issue is resolved until I am able to take the car for a proper drive.
