Make sure there's fuel in the saddle tank both sides especially the drivers side.

Was the injector second hand or new?

Or refurbished ?

Check the leak off connector on top of the injector has the seal intact.

Check everything that you removed or touched when doing the injector.

Yes, also check to see if you have the old style plastic t connectors as they can crack. Check the others to ensure they aren't leaking air.

It was refurbished. Im thinking can it be the injector itself. I will take it off tomorrow and take it back to them.

Can i post a video on here?

I checked all lines and everything on the engine bay, when the old injector was in place, the leak test was smooth. However after the refurbed injector fitted, that particular injector is blowing air into leak line, other injectors are fine.

I will update soon as refit that injector.

Other than a leak in lines, i dont see any other way for air to get in other than the injector itself.
Could it be an open injector?

Why is air only blowing through injector number 3 and not the others. Can it be the injector?

It must be, there may be a hairline crack down the body, some refurbishers miss that. I do not see otherwise how you get air on the leak test, unless the leak tester is having trouble sealing with the injector.

No dont think so as i used the leak tester on that injector before.

Basically he took my injector and said he replaced a valve inside.

The injector is leaking back the same amount of fuel as the other ones. But the difference is its spitting the fuel with lots of air.
So im not sure what to make of it

Buy an injector on ebay, euro car parts, dealer etc swap it out and see if it does the same.

If so, take it back to the refurbisher and get your money back.

Who did the work?

Don't do that on a common rail diesel. At best you will loose fuel, at worst high pressure diesel will cause a horrible injection injury.

I was careful to only loosen it a little bit, does the system automatically bleed air through high pressure pump?

Who refurbished
Its a company called ‘fuel injection Seevices’ in Cardiff.
I just spoke to the guy he said to bring the injector in, he will have a look.

Im thinking if this injevtor is leaking back the same fuel as the other ones, does that mean theres no problem with it in the eyes of the refurber, although its leaking alot of air through it?
