Not really anything yet. I'm going the get the beast to the shop tonight to be looked at tomorrow. If it's all four left injectors, the cost will be about $1200. Not horrible. The guy in the XFR thread had his four injectors changed at a Jaguar Dealer and paid just over $1700. I'd not use my local dealer even if they were cheaper. Or closer. Or both.

I'll also have them do the tranny pan and fluid swap for a couple hundred, since I don't have access to a lift anymore.

ALSO will have them recheck the water pump since it's there, it was fine last time I checked, but that was almost 18 months ago. Here's hoping. Of course, MAYBE it was changed when it came off-lease right before I bought it. Who knows, I never got the paperwork from Park Place.

So, as always, More to Follow.

 

Okay, we're waiting.....

 

Yeah, me too. Since it was in the shop, I had 'em do a plug swap, and since THERE, a compression check. Well, the plugs were nasty and ONE plug on the misfire side was absolutely coated with raw fuel......... like an injector got stuck open.
The parts have been ordered and will be installed on Monday.
Again, since it was there and I no longer have a lift, I will have them drop the tranny pan and refill the fluid, since I already bought that stuff about six months ago and it's been sitting waiting for me to FIND a lift.
So anyway, So Far the only problem was the one injector and the nasty plugs.
All-in, the cost was quoted to me of $1850, +/- a bit. Not horrible for all what they did.
Sad thing again...... I'm quite capable to do ALL this work, but am limited to a worthless back.

Summary; Either late Monday or Tuesday sometime I should have it back.

 

Are they cleaning the rest of the injectors ? I sympathize with the back, I've got spinal stenosis so standing over the engine gets to me quick.

 

Replacing all four on the even side since they are right there. If the opposite side goes, I'll replace those four at that time. There is little related work to swap either side, so it'd be another $1200 for just the odd-numbered injectors.
I'll throw a bunch of cleaner agents through a few times, maybe gain some time on the other ones.

 

Woo Hoo!!!
The #4 injector was the bad one, and had all four on the left changed along with all eight plugs. I had SUCH fun driving it home!
So anyway, the total deal was $1800 and included the following...
Check DTCs
Check Compression - good
Replace eight plugs, mediocre
Check eight coils - good
Check low-pressure pump - good
Check high-pressure pumps - good
Remove and check left four injectors - one check bad, others "ok"
Replace four left injectors
Check Water Pump - good :-)

Tech noticed possible S/C Torsion Isolator noise when initially started prior to repairs, nothing noticeable afterwards but I was advised to be aware and follow-up on it.
Change Tranny pan, filter, coupler and fluid - on my request - took ten quarts (9-1/3) of fluid to full.
Road test, had "Rich Condition" pop up once, probably due to excess fuel remaining in system.
______________________________

I took a detour home to add a few extra easy miles, and the RICH DTC never came back, so probably good. Cat on the left may have gotten a bit fuel soaked, so I was advised to drive a good 100 miles or so to get everything nice and hot and cleaned out. May experience an o2 sensor DTC that would probably clear after the trip.

I also bought some oil and will shortly go do a change as there is probably a good amount of gasoline in the oil pan by now. My one-year point is in a couple months anyway, so no big deal.
Don't tell anyone, but I bought that new Valvoline New Engine Oil specifically made for GDI engines, with additives to clean and prevent buildup of carbon on intake valves. I know it's not "Jaguar Approved" and all that, but does it REALLY make that big a difference? Answer: No. Heck, it's made FOR this exact style of engine. Valvoline evidently didn't pay Jaguar enough to get included in the SPEC.

Summary...........
I didn't need a $2k spend, but not that huge a deal and I got my car back and now I don't have to worry about the water pump (for now) and the tranny service that I was going to do anyway.
Course, the OTHER four injectors may need some looking after. I'll use some extra detergent and such for awhile in the fuel. Hopefully that'll avoid a recurrence.
Good-To-Go!

 

Pretty much what happened to me. One artifact I noticed is that after having the driver's side injectors replaced was an increase in mileage. You might want to keep an eye on that - it was a nice surprise. Glad to have you back on the road.

 

So what does THIS STUFF actually mean???
Current Fuel Trims per cylinder, Long Term per bank and Short Term per bank.....

 

By the way do we assume you saved the injectors and will get them cleaned and tested. Would be interesting to see the spray pattern before and after.

 

I told the tech I did want them, but when they were put in front of me I lost all interest. I have WAY too many projects going on now, and since I'm a physical wreck right now I can't even make a dent it those ones. I don't need another right now.

 

Possible vacuum leak with high STFTs. Check the fuel trims at idle then increase to 2500 rpm and note what happens. If the STFTs come down towards zero, there is a possible vacuum leak.

 

I thought about that, but I also had/have a "Rich Condition Bank 1 & Bank 2". Figured it'd be Lean with a Vacuum leak. Beats me, man.
I did do the off-idle thing and they did drop. If I remember right, the Long Terms went up at the same time.
Grrrrr........... the shop may have missed a line or something. Bah.

 

In case something had to relearn parameters or some such weirdness, I did charge up the battery then did a hard reset.
I'm about to take it for a spin again, and keep an eye on those trims AND the vacuum readings.

Maybe I should finally pull the trigger on a GVIF and an Android Mirror device.

 

You need to get them and keep them should you need another- or sell them on here for someone who may just be looking for one.
Looks like you are going back to the shop anyway.
FWIW I read the BMW guys being able to clean them up after soaking for several days

 

ALL IS GREAT!
I went for a good ride after the Hard Reset, and everything went perfect! The long term fuel trims went to zero, and the short term were barely negative and stayed pretty much there forever, bar acceleration and such. Zero DTCs and Such Fun! The last half of the trip was in Rush Hour so I didn't get to play at all, but still a good ride.
Oh, I do have ONE problem from the Reset....... the Driver Window now won't auto-up. It goes down fine, and the Pax window goes both ways along with the 1/4 windows. I tried resetting the Driver Window probably ten times, but no bueno. I'll deal for now.
Therefore, mark this thread as resolved!

 

We got a guy here that cleans and tests them and it wasn't to expensive. In this case all you would have to do is drop them off and pick them up a few days later. Also would be useful when one of the other 4 goes. Just my thoughts

 

And judging by the visible carbon on them its a good possibility.
Yes I posted a link to a place in this thread in that area.
It would be my first stop.

 

Maybe a dumb question, but how would a special oil help keep them clean?

 

I assume that is a rhetorical question as the fuel quality would be the contributing factor to some of the carbon build up. This seems to be the problem with these DI head designs . Audi has a problem with this and they use special oil also. Interesting to see the back of the valves using spec vs any oil .

 

By being the first oil designed for GDI.
How GDI engines have survived for 10 years before this oil is unknown to science.
And its has no proven track record of being used in a GDI engine.
Is their marketing material not good enough for you?
