I hope this in not indicative of the old Jaguar electrical issues?
We have not even made it through our first week in our new XJ and the check engine lite came on. It has not hurt performance yet but something is definitely out of whack. We could not reach the dealer as they were closed and the service department is not open on Sat. The dealership is also 300 miles away?

Any ideas?

 

Go to any autoparts store, they will read the code for you and you can google it

 

Sounds like it is something minor. I had it soon after getting my car and it was nothing wrong but one of the smog software parameter was too narrow. They needed to widen it so it would not alarm during some cold starts. Too bad the dealer is so far away. I have the same problem it takes me several hours driving to get to the dealer.

Hopefully, as suggested above, you could go to an autoparts store and they could just reset it for you or you could try purchasing a code reader/reset device. They are fairly inexpensive.

Good luck,

Albert

 

Never had this happen on my XJ but on my other cars the light usually indicates a malfunction of the pollution controls. And believe it or not, sometimes it indicates that the gas cap is not tightened down properly. If you find that is the case, tighten it, wait a while, and the light will turn off. Hope it is that simple!

 

You guys are awesome. It was an easy fix. I went to the local auto parts store and they were able to hook up and said I had six codes effecting emissions. She was able to clear all but one. I thought that sounded a little weird so I went back to the gas cap that my wife had checked for me and took off the cap and screwed it back on making sure it clicked three times as the gas cap door says. Started the car up and the warning lite was gone.
Big relief on that.
Thanks for the help guys.

 

Bummer, the lite is back so I made an appointment with the dealer to get it fixed. The service manager did mention that we should only use high grade premium from specific refineries such as Chevron, Conoco and 76 as they put and additional additive in the fuel. Anyone aware of this?

 

I call nonsense on the Service Manager's fuel recommendations. You are allowed to use even regular, 87 octane fuels, according to your owner's manual. The engine computer will simply adjust the timing and you will loose less than 10HP by running regular fuel. I ran 91 premium, regardless. Most experts agree that there is no reason to seek out certain fuel brands as nearly all independent brands purchase from the same refineries.

The point is that the likely reason is NOT the fuel brand or octane number but, the same smog parameters that triggered my engine light. They need to re-flash to engine computer with the wider parameters.

Went to the dealer and after three hours told me the 02 sensor was bad and they had to order it. Said I would have to come back in when the part came in.
Now keep in mind that we are 3 1/2 hours away from our dealer and since they are not open on Saturdays we have to take off work to get there on a Friday. Needless to say we are not happy and when I challenged the service manager on finding a sensor available in the Salt Lake City area he said it was an exclusive part to the new motor and not available. I told him to tell his manager that I made one trip now they have to send a technician to my house when the part comes in to fix it.
We all know the answer to that one.
I sure hope this is not the beginning of problems? We really love the car and for the price expect above and beyond performance and service from the dealer.

Distance from the dealership is going to make even minor attention to the vehicle outside scheduled servicing a big inconvenience for you.

Good advice on having the codes read and I see from post #5 you can get this done locally. Code reading is always the first stage in troubleshooting and will be exactly what your dealer did to identify a faulty HO2 sensor.

If you get further issues, post the codes on the forum for advice on the possible causes. You should post the codes and not what the local auto parts store gives as a description. Generic code descriptions often vary from the Jaguar DTC listing and can be misleading.

I think it is annoying the dealerships are not open on saturdays.... In Michigan, they don't even stay open after 5PM but 2 nights a week. I would imagine most people whom own Jaguars are working while the dealer is open. Just frustrating...

Glad you got resolution on your issue.

 

Dealers are franchises. Same over here but they do open. Largely for sales and less so for parts. I suspect not for repairs but have never asked (I don't get them to do repairs).

A cheap OBD tool means you can DIY what the codes are. Say a faulty O2 sensor - any shop can change it if it's not something you can DIY. (They can be "rather tight" - English for welded in.)

 

Though I have nothing of value to add to this conversation I would like to challenge all the manufactures including Jaguar that in this day of completely digital displays why do we still have a check engine light? Wouldn't it make more sense to tell ME, the owner, what the exact problem is so that I can make an informed decision as to whether to keep driving or immediately pull over? That is very valuable information when you are doing cross-country trips and may be in the middle of no where at the moment.

And specific to the Jaguar what is the point of having a TFT display if it isn't used for anything? When I switch to sports mode it would be awesome to be information overloaded. I am driving the car at the limit so why not give me as much information as possible and let me decide what is and isn't important. There is no reason in this day an age why we still need to hook up a OBDC II to see error codes. Especially in a car with two digital screens.

 

The light (and its detailed behaviour) is mandated by the law. Simple as that.

They could add detail on the display (when the car has one) if they chose. I wish they would - even if it was by default off (since most owners seem unwilling even to check oil or tyre pressures).

 

What is the extent of Jaguar Concierge or Jaguar Roadside assistance with things like this? I was reading online and it says they will come pick up the car, leave you a loaner, and bringing it back when all is fixed.

That would have saved me an hour an a half drive this morning....

 

We will agree to disagree. The fact that the law whether is be UK law or German law or American law that requires a check engine light does not forbid them from going further. It is just a required minimum amount of information required. There is absolutely nothing stopping any car company from giving the owner more information. Other car companies have TPM that gives exact tire pressure by tire. Jaguar choose to only tell you that a tire is low.

So it is really not as simple as you claim it to be.

 

This is where in-vehicle telematics like OnStar (or in my case - Mercedes mBrace) come in handy and I wish Jaguar offered a similar service. mBrace can do a remote diagnostic of the vehicle and send you an email of possible issues before they even fail.

 

I don't see any difference in what I posted and you did. Where did we disagree?
