Jag XFR knocking noise from engine, very worrying

Just had a call from the JMD manager, apparently a fuel injector has gone and this has caused the problems. They are now getting costs.
I'm really fked off with this all now. And will most likely get shot of the car, when it's fixed.
Fuel injectors would have been moved over from the old engine? Or more likely water in the tank?
I'd argue that any problem under the bonnet is down to them for 3 momths. Then reverts to the warranty of the components, if any.I'm really fked off with this all now. And will most likely get shot of the car, when it's fixed.

I've been told the injector is stuck open, hence the smell of petrol and the white smoke. These parts retail at £450, but I'm not convinced. Given the poor diagnosis for the past, I feel there maybe other issues. Can an injector be fixed if it's stuck open? Would water in the petrol tank effect all injectors or can it only hit just one?
Nothing to do with water in the fuel. My guess is the injector stuck open because of a bit of muck in the fuel system - It would only take a microscopic bit of grit to be introduced into a pipe - and they would have disconnected all the fuel pipes in the engine bay during the engine swap - any disconnected pipe upstream of the filter could introduce muck into an injector. This is no coincidence.
Nothing to do with the fact your old injectors have probably been left lying around collecting crap / being trod on whilst awaiting the new engine from Jaguar then! If the injectors were working correctly before then I'd argue very strongly and yet again, that's down to their incompetence.
I was told the xfr doesn't have a fuel filter.
There wasn't one to change when I brought it in for the major service, back in December.
Anyhow, JMD have called to say they will replace the injector free of charge, as a good will gesture.
But I've really lost confidence in the car now.
I've been lucky so far, but that's not going to continue.

The injector has been changed and they driven the car about 50 miles to test it.
I should hopefully hear more on Monday.
Thinking ahead though, should there be some kind of "warranty" period on the non-serviceable parts?
The injectors sound like they are very delicate and a damaged one will cause havoc. I've been lucky to have this replaced without any cost to me, but what would happen when the next expensive part fails (which could be linked to the engine change and possibly caused by them).
And would one injector that was stuck open cause the car to be running that poorly?

If one injector is always open then pressurised fuel will be continually being forced into that cylinder. It is bound to seriously upset the running and the fuel can only get out via the exhaust system - might also have poisoned the cat.
If the injector was stuck shut then you would just get a misfire on that pot. Still down to your JMD being a numpty and JLR should kick their collective arse - especially when you are already talking about parting with it - quite understandable and probably not buying another Jag either - they don't need publicity like this, especially when the product was previously acceptable.

Based on my experience, Jaguar don't give a flying fk what the JMDs do.If the injector was stuck shut then you would just get a misfire on that pot.

Really sorry to hear that it's still not right after all of the work carried out. Electrically all of the injectors are totally separate but the common denominator is the fuel, which they all share from the same supply. Assuming your 5 litre has similar electronic architecture to my 4 litre, then a P fault code identifying which injector is at fault, would only be thrown if said injector had failed electrically - not the case with one stuck open.
I'm afraid it's back to the dealer for another injector - could just be the one they replaced but very doubtful - must be either contaminated fuel from source or the sh ite they allowed into the system when it was kicking around the workshop floor. These cars need virtually operating theatre conditions when stuff like this is involved.

I had a phone call from the manager today, with good news.
They will be replacing all the injectors, as the one that failed was not the new one that was put in.
There was no reason why it failed or the source of the issue.
It's really weird. I have a failure and there is no admission of fault, but (and thankfully) the failure to corrected with no cost to me, only the inconvenience of the lost of my car for a number of days; however i am given a new courtesy car to keep me running.
I've also asked about a warranty to cover everything under the bonnet (all components directly or indirectly related to the engine swap out)for the next year; they will get back to me on that.

You said in an earlier post that there was no filter - that seems bizarre, have you checked with them? As for flushing out the tank, if there is really no filter then I would not advise that at your instigation - they could blame you in the future if anything is dislodged but not completely removed and gets forced into the new injectors.
I know it must be frustrating for you but at this stage I would let them replace all injectors - if they want to flush out the tank, let that be their decision. Surely at the price of 8 injectors, they will want to protect their investment however that might be done.
We now know why JMD's charge such a high hourly rate when compared with honest local places!

Found this:
"The early car 4.2ltr the fuel filter is in front of the rear axle by the side of the fuel take on the left hand side. 2010 model year with the 5.0ltr engine does not have a fuel filter. There is a pick up filter in the tank which is not serviceable"
So there is a filter of somekind, but not the usual one that can be replaced.

XFRFred - that's really bad luck but stick with it.
I had to have new injectors when my XFR was 2 years and 22k miles old (under warranty) - car has been fine ever since and is now 4 years old with 40k miles.
And I never had a problem with my previous XFR that I had for 3.5 years.
You've just been (very) unlucky but I'm sure it will get sorted and it seems like the dealer/Jaguar are at least looking after you.
The XFR is a great car - when it is working!

Just an update to this, as there are issues with the running of the car.
As mentioned, the car went back to the JMD to have all the injectors replaced, i happened to have the car for circa 2 weeks and covered just over 400miles.
There is now the issue where the car seems to be running rich and there is an EML on the dash.
It's going back to the JMD today, but the car seems to be lumpy as hell at the moment.

Any ideas on what could be causing this issue?
