Hi All Jaguar Enthusiasts,
Can anybody give some advice on the electrical problems I have with my 2009 2.0L X-TYPE Diesel.
I have 3 codes that I can simply not erase!
P0105, P1000 & P2337.
Firstly, when I turn on the ignition the yellow glow plug light stays on for several seconds then continuously flashes instead of going off! This then continues to flash whether I start the engine or not
The car starts first time and drives slightly underpowered although not as in full limp mode!
I've changed the turbo actuator, the airflow meter, EGR valve and lower sensor from the intercooler but none of this has helped!
So, can anybody out there give me some information or advice if you've experienced or seen this kind of problem or fault?
Thanks

 

The 105 code is a malfunctioning cylinder #5 = coil, wiring, injector
1000 code is a malfunction causing the M.I.L. Light and has not been repaired or the drive cycle after repair has not been completed. This will turn to 1111 when all is right.
2337 code is usually an injector problem.

Try this, it's for Mondeo but same on the X Type

 

Thanks for the quick info Dell, all suggestions are a help or indicator of where to look next!
Didn't mention but I've replaced all four injectors and cylinder 2 knock sensor which relates to 2337 code.
Thanks

 

Dell, keep in mind that he has a diesel, not a V6 petrol/gas engine. So, P0105 is not going to refer to an injector problem. Someone would need to post up the DTC codes for a diesel X-Type. All the charts that I have are for the 2L, 2.5L and 3.0L petrol/gas engines which are not relating to the issues of this car.

Keith, the P1000 code is just saying that you have not completed a drive cycle without having a code present recently. So, ignore that code for the moment. The P2337 is saying that it is a problem with #2 cylinder having excessive knock. This can be caused by either a failing knock sensor (or one with damaged wiring) or it can be caused by a leaking injector. Now, when you put in the injectors, did you notice that the injectors had numbers on them? #1 injector does not go into cylinder #1 ironically, it goes into cylinder 3. Could you have mixed up the injecctors because of this? Trying to narrow down issues. From what I can tell, the P0105 code refers to a MAF sensor issue on the diesel, so, it could be simply the MAF sensor needing a cleaning.

I am struggling a little bit here as I have tons of charts for the petrol engines, but none for the diesel engines and I am finding answers all over the place on what the codes mean for your car. The other possibility is that you didn't tighten down the knock sensor sufficiently and the sensor is slightly loose. This will cause the sensor to move and rattle, making the sensor think that there is knock going on that isn't truely there. So, that might be something to look at too.

 

Doh!
also isn't there something with the diesels that new injectors have to be coded upon installation?

 

Thanks for all info and suggestions guys and please keep rattling your brains as it all may help? Code P0105 relates to a Barometric sensor fault? which I can't clear but a little unsure as what to change or explore? Possibly high pressure rail? Knock sensor (P2337) is definitely tightened correctly, all four injectors are new and recoded to the correct fire order 1,3,4,2.
I've been running an X-Type 2.0 Diesel since 2007 and covered over half a million miles (although not all on this same vehicle) I kinda know them pretty or fairly well but never had this issue before.
Enjoying all feedback so please keep it coming guys!
Thanks

 

I've have a bad catalytic converter for awhile (P0420) and my P1000 code recently changed to P1111. Don't understand why since the convertor code is still there.

 

I don't think that this is related to my ongoing issue but are you saying that the fault code for the cat is still there after attempting to ERASE CODES or is it just still there after P1000 changed to P1111.
I'm not sure what diagnostics your using and I'm by no means an expert but I don't believe that the CODE/S will erase automatically. So if your vehicle suffers a problem thus adding a code to its system it will still need to be erased even if the vehicles fault has been corrected and the vehicle is running and driving as it should.

 

Max/Keith, codes will not erase themselves. They will remain in the computer until you manually erase them or the ECU looses battery power. With that being said, a code will cause the CEL light to remain lit until the car has done 5 back to back start ups (engine has to turn atleast 10,000 revolutions for each start up to count) and then on the 6th start, the check engine light will not remain on. So, if you clear all the codes and then you get a code back, that tells you that the fault condition is active and should make finding the problem easier. if you can clear codes and then get the CEL say 3 days later, those are the problems that I hate. Always a bugger to figure out unless you can catch the problem as it is happening.

 

You;re right, diagnostics are a bugger with these cars. My inquiry centers not on the P0420 code (I'm sure the cat is bad), but on how I have the P1111 code with that obvious fault. Doesn't seem logical, but Jaguars have their mysterious ways....

 

Think I'll have to go from the start again with my unsolved issue or Gremlins. Can anybody shed a little light on how or why my glow plug light (curly pigs tail) on dashboard comes on with ignition (as it should) but then switches to a continuous flash even before the car has started or turned over!

 

It's entirely logical if you look up what P1111 means.

It means the OBD monitors have set. It doesn't have anything at all to do with fault codes which may have flagged.

You might try reading the Jaguar documentation...

 

Point taken. So the catalyst monitor is set notwithstanding the P0420 code. I would change out the catalyst but it looks like a real PIA; drop subframe, etc. and I'm almost (gasp, choke) 80! Fortunately for me the yearly mileage put on the car is low and renders it exempt from emission testing.

 

Back to the OP's questions . . .

Keith, you are talking about a car (or rather, car + engine combination, that saw little exposure outside of Europe (including UK), so asking about glow plug conditions in a diesel engined car in an international, heavily weighted to NAS, is perhaps the reason your queries are bringing little response.

Suggest you post in the Diesel forum or, better still, head off to the UK Jaguar forum, where you will attract a more numerous band who have cars such as yours. There are a band of us here who gather around issues to do with the 2.7L V6 TTD but, these have no glow plugs (thus, none of the issues you experience) I cannot provide accurate analysis. Were it front suspension, brakes or many electricals, you are in the correct place but . . . for your engine woes, all such issues are best dealt with in the forums dedicated to that engine rather than body.

Best wishes,

 

Oh dear, I'm in the wrong part of the world 😭 haha
Thanks for correcting me or advising of my silly mistake! Kinda wondered why replies were coming in at strange times!
Big thanks to those whom took time to reply to my thread anyway and good luck to all you Jaguar Enthusiasts on the other side of the big pond!
Thanks guys

If the ignition is switched on but not cranked or started, and the glow plug light repeatedly flashes, it is probably due to the turbo electronic actuator not responding correctly.
This could be that it cannot respond when commanded to, as it uses canbus to talk to the ecu, it could be mechanical or electronic fault, and could be canbus wiring fault as well.

Paul.

 

Not at all, and questions are very rarely silly . . . yours is certainly not.
Beyond your current question, we hope to see you continue here as an active contributor.
Best wishes,
