Hi,
I am needing to replace both catalytic converters for my 2005 xtype 2.1petrol engine jaguar.

I am not able to find any for this model on the internet.
Is there a difference to the 2.5 & 3.0ltr ones as these seem to be available.

thanks
Dea

 

How about here?

I am having problems finding a cat converter for the petrol x type 2005 model. When I bought the car I did not realise the 2.1 petrol engine must be fairly rare?
The ones on ebay for 2005 are for the diesel 2.2 motors.
Any suggestions?
Dea

 

I've never heard of a 2.1 liter engine in a Jaguar x type. Are you sure it's not the 2.5?

 

Hi Jaguila, and greetings from down under.

Initially the X400 was offered as an AWD with either 2.5 or 3.0L petrol engine. This was followed by a FWD 2.1L petrol version, also a V6 but confusingly called a 2.0L by Jaguar to minimize UK road taxes. As noted, diesel engines of 2.0 and 2.2L were also offered. Initially, all were saloons; but an estate version followed from 2004. Check out the specs in this forum's downloads.

Worldwide, 2.5 and 3.0L petrol saloons dominated, but different markets (perhaps not US) absorbed large numbers of the 2.1L "baby". In both the home market and here, the significantly discounted FWD was a selling success - and today's used car market in Australia is dominated by the 2.1L. Some of the ridiculously low mileages offered in (say) 6-8 year old cars suggests that many were the family's second driver car ... lot's of local trips to school and shops but little else.

 

Sorry for the double post, but forgot to say "Hi" to dea.cea1959; and address his original request for help.

Greetings mate, from out on the coast near Coffs. Can I suggest you post an intro in our Aus/NZ section, and seek help from Dave (dstarry) and Cam (Cambo351) and the boys re purchasing in Oz.

As a new X-Type owner, you have come to the correct forum for when you need technical help (and to broaden your purchasing options via internet) but don't overlook the fact that you are surrounded by other Australian owners who have already trod the same path you are on.

And no ... nothing rare about the 2.1L petrol V6; although it is the only front-wheel-only X-Type or Jaguar to date ... check out <carsales.com.au> for Jaguar/X400, and you will find that 2.1's outnumber all offerings of 2.5L; 3.0L and both diesels, all combined.

 

You dont need to replace them it will cost you thousands!!!! The back one requires removing the transfer case and the sub frame at least eight hours of labor. If your cats are not plugged just inefficient enough to trigger the CEL; You can fix the whole problem in an hour and be done with it forever. Just by two 18mm " de-foulers" and drill one out so to as accomodate the down stream O2 Sensor and install the sensor in the de-fouler. That way it wont be directly in the flow but it still get some flow do the sensor will report the reduction in the flow to ECU and trigger the CEL. The rear O2 sensor has only function: monitor the efficiency of the cat.

I don't where NSW is? I don't know if you have emissions tests there; we used to here but the law got repealed because they had no effect on air quality. Chances are that you pass the test even with this mod because you still might be complaint but the CEL comes on even you are marginally below the threshold.

If want more direction just Google " bypass cat" or write me

 

HI bostongrun,
Thanks for that information. one problem! The cat is collapsing inside and blocking the system. The O2 sensors seem OK.
Any suggestions?
Dea

 

Luckily there is no transfer case on a 2.1L X-Type

But yes, it seems to remove/replace the "right hand" cat you need to drop the front subframe (according to the official workshop manual). This is where the $$$$ come in.

The left hand one (i.e. the front) can be accessed without having to drop the subframe.

I just had a look at what the factory cats look like. Oh dear, doesn't look too easy to fit an aftermarket cat in there...

With most cars you can pic up 200 cell "sport cats" off ebay brand new for $150 or so, and any decent exhaust shop could just cut the old ones out & weld the new ones in.

Original cats from Jag are £525 each +VAT in the UK. (that's like $955 each, by the time you get them here probably $1200 each) so going for some aftermarket ones would be cheaper for the parts...

The problem is the labour for getting to the damn things...

The exhaust manifolds are all the same P/N for 2.1/2.5/3.0, in theory you could fit the cats from a 2.5/3.0 but you'd also have to change the rest of the exhaust as well. If you can't find 2.1 cats cheap, then this might be something worth thinking about.

EDIT

One last ditch attempt, would be to bash the guts of the cat out & fit a mini cat to the rear sensor. Not legal, but would be cheap....

 

Thanks Cambo,


Your information has been helpful, welding is not a problem we have a specialised engineering business and we can do that if we cannot get a similar cat. They are cast which is some of the problem.
Can you advise how we can access a workshop manual.
Thanks
Dea

 

It's not going to be easy to weld on an after market cat. For a while I was considering buying headers for my X Type but none are available. Once you take a look down there you can see why. There is simply no space. The cat is bolted directly on to the bottom of the exhaust manifold. That's why they go out so often: a misfire dumps raw fuel right into it and your cat goes out in ten seconds if you have a misfire.

It's a bad design from the perspective of cat longevity but engineers have to consider so many things when putting these things together.

I know you can remove the head pipe aft of the cats. You could run a tool of sorts up the rear end end of the cat and ream out all of the honeycomb material inside, you might also be able to use the 18mm O2 sensor bung hole to ream out enough cat material to clear the obstruction; essentially you are making the cats into a straight pipe. Then you could use two 18mm plug defoulers to keep the business end of the 02 sensor from protruding too far into the whole thereby fooling the ECU and not getting a CEL.

The only difference you will notice is better gas mileage and increased performance if it's successful: I dont understanding why it wouldn't work.

I already did this with front bank 2 cat and never had an issue. It cost $4.00 US as opposed to $1000.00 at a dealer or $350.00 parts alone after market and at least four hours on my back. Cat and exhaust components are by far the worst things to work on because they are almost impossible to seperate.

 

Have a look at the top of the X-Type section here, there are a couple of sticky threads regarding JTIS, that is the dealer workshop manual up until 2004, it gives you all the procedures.

If you've seen a picture of the rear cat, you know what you're up against in regards to welding in a new one.

 

Hi again Dea ... and greetings Cam,

Can I add to Cam's help in identifying the JTIS sticky thread here at top of forum ...

1. With an 05 model, you may decide that although good background for early models, your car may include upgraded features and modules that JTIS does not address. I also have some worries about JTIS not being readily useable on modern Win64, Mac and Android platforms - I am NOT rubbishing JTIS, indeed Cam has given you a perfect example of how quickly and accurately you are offered a pic of your cats - but at +10yrs old, there are (imho) better options;

2. I sourced a disk based workshop manual from a UK eBay supplier <copyquality> which includes over 4,000 pages across the full spectrum of years and model updates up to 2009. The wiring guides alone make a joke of the AU$11 cost, including 2week delivery into Oz. With both Win & Mac loaders and using just 10% of a microSD card, the gotcha for me is that all files are PDF, meaning that Acrobat Reader has no drama with sections, jumping through bookmarks, scrolling, printing etc - whether on your laptop or mobile ... yes, mobile, although I don't recommend tracing wiring diagrams on a tiny phone screen. I have included a couple of local <$20 offerings for you to check out ...

3. Priceless items here on the forum are sticky threads of TSBs (Jaguar Service Bulletins), factory recalls, sales brochures of features, accessories ... as well as a long list of "How To's & Hints" assembled by JimC64; VIN decode table provided by Cam; and advice to ask nicely for a factory printout email to you of the detailed build of your vehicle;

4. Sooner or later, especially for a workshop savvy person, you will find all the info that the car itself can provide you ... via the OBDII skt with a suitable tool. Mine cost about AU$50 via eBay, but I am sure there are solutions that are cheaper; others that are better. You can check the forum threads that are dedicated to this subject;

5. My last is not a throw-away, although less a day to day workshop resource than an excellent companion for owners - and would be owners - setting out strengths, weakness, model updates and market variances. Again, price is around AU$15 including 2week delivery into Oz;

At somewhere between AU$30-90, and backed up by the friendly and experienced bunch on this forum, I bet you find this collection the best investment you will make. Sorry, so long winded, but... well, you did ask!

Thanks Cat_as_trophy and Cambo,
Looks like a solution is close. Will order a workshop manual from one of the links.
Camob's diagram will be very helpful to get me started.
