Main Dealer - Snapped Injector

[Reggey_83]

Morning, long time member but this is my first post.
So last week a sudden misfire started on my drive home. A bit of checking on here and I was fairly certain it was a faulty injector, especially as the car started fine after it had cooled later.
Due to an imminent trip to the Lake District I booked it in with Nottingham JLR who have previously serviced the car. I drove it steadily and without too many issues to the dealer. They confirmed the same day that it was an injector and quoted me £1100 for replacement…..
Rang me yesterday to say that they snapped the injector and wanted another 2 hours authorising…. At £204 an hour…. And a specialist had to be booked to remove the injector. They were unable to tell me a final cost or even give me an estimate.
Has anyone been in this situation before and Is there precedence for discounts on main dealer rates due to them snapping the injector?
Any help would be appreciated!

would have thought the quote is the quote £1100 for the job and stick to the price, differant if it was an estimate.

Not good to hear, but at least they are proposing a solution to finish the job.
I'd agree if it was a quote, rather than an estimate. You'd have to check the wording if they provided it in writing, but my guess is it's an estimate based on book times and parts costs.

Bit of a rock and a hard place situation, realistically the car is where it is and they have to fix it otherwise you need to get it collected and taken somewhere else at a cost to you.
I don’t suspect you would have got a discount if the job had taken shorter time than the quote / estimate so they don’t really lose.
you could try to negotiate you pay an hour they pay an hour

legaly a quote is a fixed price to do work, estimate is a guide

OP, I agree with the previous comment on splitting the extra cost as a goodwill gesture.

Could someone else provide some reference on injector replacement costings? Dealer VS specialist, for example.

I commented a while ago about the reasons why injectors fail. On Audis, they breakdown due to the filter inside them collapsing and blocking the output. There are companies specialised in testing and remanufacturing old or new Audi injectors with a metal filter mesh rather than the original brittle plastic and paper design which deals with reliability problems for good.

I still wonder if it's the same issue with the AJ126 injectors or if there's a pattern that can lead up to issues e.g type of fuel, additives or lack thereof, carbon build up from low mileage and short distance driving, etc.

On carbon build up, has anyone ever tried a HHO carbon cleaning service on their F-type?

Quotes usually have a disclaimer that says subject to not having unseen issues or findings.
It happens all the time where I work . Things snap ,or you find other faults which require us to contact the customer for more authority.

Agree with Stickman Steve.

Most injectors come out easily or with a bit of persuasion. They would’ve quoted on this being the case.

Injector snapping was unforeseen & therefore additional work/cost expected to resolve. I would want some ballpark for the final completed job though.

Dealer perhaps should’ve mentioned possibility of injector snapping, prior to works starting. Imagine an independent would have.

I believe the piezo electrical units on these crack and then when they're hot the crack opens causing failure, they cool and the crack closes making them work again. Could test that theory with a can of freezer spray I suppose.

In terms of carbon cleaning I'm giving a tank of V-power a go (usually I use tesco momentum) along with a can of BG44K. There has been a technical document released by landrover for the V8 engine varient to cure injector issues and missfires using this specific product in a tank of fuel so it clearly works. Wouldn't fix a cracked injector though. I just have a very slightly lumpy idle on mine only with it in neutral and the ac off which makes me think it's struggling with light fuel loads.

Hi guys, thanks for the comments and I’m still waiting to hear back from the main dealer. Can anyone confirm if the vents in the bonnet have been redesigned by Jaguar to prevent water ingress? My understanding is that this water ingress causes additional corrosion which makes injector removal on early v6 cars more difficult. Can anyone confirm?

The vents were repositioned for the AWD cars, but I'm not sure if that was done to avoid water ingress.

I don't think you can reasonably associate redesigning the vents to prevent water ingress. I'm sure Jaguar would simply state it as different designs for each model, year, etc as is done with so many other external parts.
If they wished to address water ingress through that point I'm sure they would have simply extended the engine cover or some other workaround
