Fixed Engine Amber Light

Hi,
Yesterday while I was returning home on the highway the amber engine light came on. Light is fixed and no engine power loss.

Last summer the same thing happened but then the amber light went out by itself after few days.

Last friday I went to the dealership to change the headlights and the dealer connected official diagnosis to code new headlights. During process he tell me if i had modified engine software ecu because diagnosis reported a different software from original. However dealer deleted all previous error including this summer error.

I have not modified the engine control unit but I do not know if the previous owner has modified it, even if he told me no.

Today i called dealer and he tell me to try to start car and stop it for 5 times. In this way amber light it should disappear but I haven't tried yet.

I read online that it could be a lambda probe, is it possible? how could i do to verify?

My car is a 2.0L P300 with 25000 km and 3 year of life.

Some advice?

Witaj,
On the bigger engined cars the most common reason to the check engine light is that one of the O2 sensors has gone. Don't know if it's as common on the 2.0 and the only way to find out is to connect a code reader so unless you have access to a code reader it's a dealer job.

If the car actually is remapped, as the dealer's ECU software version comment implies, that could of course also be the reason. If it's nothing obvious like an O2 sensor perhaps the dealer could install the stock 2.0 engine map to see if that helps.
 
I recently had the P0420 code thrown on my P300. Reset it, came back after a few weeks. Reset it again and came back after a few days. Dealer's conclusion was a bad catalyst converter. At 40k km's i was rather surprised that it went out that fast. They managed to get the part under warranty although, phew.
But it could be a bad O2 sensor too.
 
On this 2.0L engine the cam position sensors are prone to failure, which trigger this check engine light. Indeed you need to read the codes to ascertain.
If this is it, you will note that the overall car performance is reduced, almost limp mode. If the dealer is close by you can drive cautiously to there. But if he is far, better to have it towed.
Had this happening on my F-Pace at almost 3 years (40KKM), called the road assistance which checked the codes and confirmed both cam sensors were failing, car towed to the dealer and taken under guarantee.
Good luck.

I don’have any obd2 code reader but i would buy one compatible with my 2019 car.
I found VXDIAG VCX SE on aliexpress but i don’t know if is work well and it cost around 270€.

If the car is remapped, shouldn't the o2 sensor be inhibited?
However, dealer told me that if I don't load the original software he can't write to the ECU. This is very strange.

i hope that my problem is not the same as your.
In this case i’ll remove cat and remap.
I can't imagine the cost of the catalyst

I have not any change on car performance.
as you advised me, I need to read the error. Can you recommend me some obd2 reader for Jaguar?
 
today I noticed this strange sound of metal when I accelerate to low revs. I think it may be the exhaust valves. Is it possible that the problem is due to the exhaust valves?

Have you looked under the car , other members with experience of this will help

Sounds like a rattle to me?

Perhaps someone else with the same car can confirm whether or not the sound is abnormal?

I think the 2.0 litre F-Type only has one valve on the rear exhaust which (when looking at the car from the rear) is on the right hand side? Worth getting under the car and trying to move the valve in and out by hand to see if it’s working ok (some owners use a copper grease spray to help with lubrication). Also, when you’re there, you could check its movement with the help from someone in the driving seat......obviously making sure that it’s safe for you to do so. Furthermore, check to see if any of the exhaust components are loose or touching/vibrating against something else.

Here’s a link which shows an exploded view of the 2.0 litre rear exhaust parts.

Hi guys , any idea what would remove the carbon deposits on a v6 exhaust inside of it around the valve area , sorry don't mean to hijack this thread

yes is like a rattle, a metallic screech.

Thanks for the link of my exhaust.
This afternoon I got under the car and I can confirm that I only have a valve on the right side when looking at the car from behind.
I tried to push the valve with my fingers and it didn't feel like it was stuck. however I still sprayed some wd40 on the valve stem and tried to open and close it with my hand abount ten times.
After that i started the car but the rattle sound is the same. It is less audible with the valve closed and more with the valve open.
This weekend I'll try with a friend to see what happens when the button to open and close valve is pressed from the car.


I'm starting to worry about the noise, I don't want it to be something more serious.

Thanks
 
If it’s less audible with the exhaust valve closed and more with it open, there could be an internal fault?

It’s worth checking to see if any of the other exhaust components (including clamps, nuts etc) are loose or touching/vibrating against something, as this could also cause noise to travel through the exhaust.

When your friend helps you with the car on the weekend, perhaps you’ll find something?

Good luck

yes, I have the impression that with the valve open it feels a bit more.
yes, I have the impression that with the valve open it feels a bit more. but it is possible that it is only my impression. This we will have a little clearer ideas, I hope! however today I made a new video where the rattle is better heard.

another thing, today the amber warning light went off by itself: I started the car, the revs went up to 1500, then for a moment they went down to 1300, the light went out and the revs went up to 1500.
 
I can definitely hear the metallic rattling noise much clearer in your new video......something isn’t right there?

Have a look at this link on the 2.0L P300 (‘Mystery rattle noise solved’). I've also attached the photo from it....

I don't know if the construction with other F-Type's is alike, but in the P300 this can be the reason for an annoying
rattle you can hear around 1400rpm. We mostly heared it around 60kmph [ no wind or tyre noises].

It sounds like a faint version of the "rattle" used to scare birds from an orchard..

The source were [ not confirmed ] two brake lines near the exhaust and the petrol tank, touching the frame...
Could just as well be next to the point where the earthlead from the battery is fixed to the body.

Maybe someone who spend time underneath the car can verify the exact location...

In the circle the mechanic placed the black rubber pieces to prevent the rattle.

Next to earth lead, behind axle, LH side. Two fuel lines..
Idle vibration is the bearing of the translation actuator of the wastegate.. .. nothing more as far as I know. Let them check your fuel lines,
maybe that solves it...


If that's not the cause of the problem, you need to thoroughly check the exterior exhaust components and heat shields to ensure nothing is loose or vibrating. If it isn’t, the rattling may be coming from inside the exhaust and could be a worn/faulty baffle or exhaust valve? This link ('Exhaust rattle at low RPM') includes a video of what the owner says 'turned out to be a loose baffle' inside his F-Type R exhaust.....https://www.jaguarforums.com/forum/f-type-x152-72/exhaust-rattle-low-rpm-184078/ Also included in the link...."Not sure if its just a stone caught in the heat shield or something."

With regards to the recurring engine light issue......as well as earlier replies in this topic, there's some good info here.....

Glad the light has gone out for the time being though :)
