Hey,
I have jagaur s type 2006 ,3.0l v6
I had my engine check light on while driving and before engine strated
So I have reset the computer , by disconnecting the battery , and there you go check engine light was gone while turning on the engine and while driving , it was only flashing while turning the switch , but while engine turned on no lights was flashing and everything was fine ,
So I was driving the car a couple of dayes everything was fine , now , today I started the car and engine started to go back and forth like kicking very weird feeling , so I immediately turned off the engine , and second time I tried to start it , it just won't start , any idiea whats going on ?

 

Read the Diagnostic Trouble Codes (DTCs) through the OBD port and post them here.

Do not operate the vehicle under any conditions that cause the Malfunction Indicator Light (MIL) to flash. Flashing MIL indicates catalyst damage is occurring.

 

Good to know

 

So far this poor car has been ignored in its attempt to alert the OP to a fault and then abused.

+1 read codes.

 

Can you read the codes without turning the engine on ?

 

Can you read the codes without turning the engine on ?

 

Hi Simon99,

Welcome to the Jaguar Forums! It's great to have you with us.

Yes, a scan tool can read the diagnostic trouble codes by turning the key to position II (ON/RUN) without starting the engine.

Probably the most common cause of the flashing Check Engine Light (CEL) is excessive engine misfires that allow unburned fuel into the exhaust which can lead to rapid destruction of the catalytic converters.

Please keep us informed.

Cheers,

Don

 

Ok , so I have ordered an odb2 scanner for the codes, it will.take about 2 weeks to arrive with Amazon,
Should I dissconnect the negative port of the car battery so it will stay charged ? is it safe to do it with the jag
What do you think .

 

Yes, it is safe to leave the battery disconnected, but first check to see if your radio requires a security code after the battery has been disconnected and if so, that you have the code. If not, you may be able to retrieve it at this website:

Radio Codes
Also, it's a good idea to put a towel or such over the trunk latch to prevent the lid from latching, just in case the lock barrel is seized and won't open with your key.

So I have checked fault codes with Launch creader 319 odb2 scanner , but it did not come up with no fault codes
, And engine light still on and blinking in various times
Also I have seen small lick under the engine.

 

It was misfiring when I turn on the engine , turned it off , torned it on second time and it went off after a second , then it want turn on no more .

 

Hope it's nothing big to fix , and I can do it myself
What do you think guys

 

Hi Simon,

Have you connected your scan tool again to see if any diagnostic trouble codes have been stored? If the engine is misfiring, it is almost certain that DTCs will be stored.

Cheers,

Don

 

Yes , I have connected it but no codes would appear even tough check engine light is flashing .

 

Simon, sure looks like your IMT o-rings are leaking. A very common issue on our V6 engines. When the valves leak they can cause a vacuum leak too.

I am attaching a link that will describe how to R&R. Within the link is another link on a simple way to check if they are leaking.

If the battery was disconnected then the fuel trims would have been reset and it may be as a result the car can't flag codes to help say what's wrong.

If anything is leaking the fuel trims will show it.

 

Hey guys do you recommend to replace the valve gasket kit for these situation

 

The OP disconnected the battery on the car and left it isolated for a good period of time. This looks like a "hard reset" to me; his stored error codes and fuel trim data will have vanished, making the process of running diagnostics difficult, at best.

In terms of the oil leak, it may well be coming from the front main (crankshaft) or pan seals. Taking the bottom engine cover off and having a look-see would e a good idea, as opposed to jumping to conclusions...

 

Hey,
I really can't do that since it would be pricy to take the car to the garage since it wan't start I can't drive their ,
So you don't think the problem in the spark plugs , since it was indeed driving clean before it went misfiring on the spot without even shifting gears .



"Disconnecting the battery (a hard reset) only clears adaptations held in volatile memory such as fuel trims. It does not clear stored DTC's triggering the MIL. The only way to do this is to fix the cause

From the pictures, it does appear that the IMT o-rings are leaking. It is also very possible the valve covers are leaking as well. That would make it look as if the oil pan gasket/seal is leaking. I do have a DIY in the "How to section" on oil pan gasket/seal replacement. Before going the route I did. I would make sure oil pan bolts are torqued to proper specs. There were a few of mine that were loose.

My guess is that the IMT o-ring is leaking as with the spark plug seals allowing oil to gather around the spark plug in the spark plug wells, very common on these V6 engines.
