Ignition coil -- 2 different ones depending on VIN!
 

Online & in local parts stores, they have one Ignition coil for a 2000 XJ8.

Many list W0133-1604076. AutoZone says theirs is OEM. $107.99. Jaguar Dealer parts ($166.50) says there are TWO different ones for a 2000 XJ8 depending on the last 6 digits of the VIN!

So, now I’m concerned about buying & installing the wrong one. Don’t know what the result will be other than it probably will not be optimal performance. I’m leaning towards paying the inflated Jaguar price to be sure.

Steve,

there are 2-pin and 4-pin ignition coils on these cars. They are not interchangeable as the connector is different!
The best way to check whether your model is equipped with one or the other is to remove one of the black plastic coil covers (6 (or 8?) bolts in total) and see yourself!
(Just takes 5 Minutes but then you will be 100 percent sure!)

I would go for a used coil!
They usually sell on eBay for around 50$ (sometimes less).
(I was lucky and got myself a spare coil off eBay for 1$!) :icon_razz:

HTH,

David

Sounds like your ***********'s price is way overinflated. FWIW, My local Jag dealer recently sold the 4 pin coil to me for $92.00

David,

I have heard about the 2 & the 4 pin connectors but that the change was based upon the model year.


From a different forum reply:
“The difference is AJ26 and AJ27 engine management

The 1998 normally aspirated (AJ26) has a 2 wire coil and the 1999 to
2003 (AJ27) have a 4 wire coil”

If it was a simple as 2 vs 4 pins than if I got the wrong one it would be obvious. If they changed in MY mid 2000 from 2 to 4 pins than why don’t all the various web sites selling coils ask for last 6 digits of VIN?

I don’t have the skills or equipment to test any used coil & my confidence in such testing is not great since my former mechanic supposedly tested my #4 coil last year & pronounced it OK when in fact it needed to be replaced.

Sinister, I wish I could buy it from your Jaguar dealer! I am absolutely certain they would have the correct one. I think I will call them to see.
(I bet they will not ship it to AZ since I have a Jag dealer here.) $92 vs $167!!

Which is it?

Thanks,

You probably have the 4-PIN coils.
But as I suggested earlier you would be 100 percent on the safe side if you confirmed that yourself on your car.
And it is as simple as 2 vs 4 pins!

And again, there is no reason not to get a used coil for about 10 percent of the price of a new one.
Especially if your local dealer is that expensive...
To change a coil is a 10 minute-job max.

Pending the age (/mileage) of you original coils, it might just be better to replace them all, unless you don't mind getting issues again to sort out. Mine where 180Kmiles old when at least 1 failed (no DTCs, so took some time before I found out), and as one can’t be sure what you buy secondhand is good/young, I decided to bite the bullet and bought all new ones.
As David pointed out, there are only 2 versions, the AJ26 2 pin ones and the AJ27 4 pins, and the 2000 XJ8 has an AJ27 engine.

Avos you are right.

But with cars in general and Jags especially it really is no question IF you'll get another issues. It's more WHEN it will happen.

With our old cars we will never be on the safe side.
So to change a whole set of coils with new ones will be 850 - 1,400 $ of material. And then...?
What if the tranny fails next or the rear axle or the tensioner or whatever...?

We simply cannot change every bit and piece that might fail in the future!

And as I stated earlier, to change a coil is a 10 Minute job on Bank 1 and more of a 5 Minute job on Bank 2.
So the OP has not to be afraid of that fairly easy task even if it will occur again one day.
In my opinion it is worth the saved money just to change one coil with a used one.

What I would do is get me the used set of 4 coils for 150 Bucks off eBay, change the broken one and would have three spare coils just in case...

Just my 2 Cents...

10 Minute job Bank 1
 

David,

I assume you’ve done this on bank 1 b4. What exactly did you remove to enable access to the 6 bolts holding the cover on? Do I completely remove the air filter box and detach the entire air intake hoses at both ends? There is other “stuff” going from sections of the air intake hose or duct to the engine.

As you can tell I am not a mechanic & don’t wish to remove more stuff than necessary due to concerns about putting it back correctly.

Thanks!

Steve

Solved!
 

Voila! My 2000 XJ8 has the 4 PIN LNE1510AB ignition coil.

No, I didn’t yet remove the cover & have a look. <GRIN>
I just realized I could look at my 12-2009 Jaguar Invoice where they changed an ignition coil & MAS!

BTW, Today I did call all 3 MI Jaguar Dealer parts Departments.
(B4 I thought to check my old invoice for the part #)
Jaguar of Novi
Jaguar of Troy
Jaguar-Saab-Land Rover Lakeside
2 of 3 state that I must look to see if 2 or 4 PINS & Last 6 of VIN will not help them. 4 PIN is LNE1510AB, $153 and 2 PIN is LCA1510 AB, $96.
The 3rd was more confusing & also said XR827823 --$96--Which I now think is actually for an XJS. He said if 4 PIN, one choice, if 2 PIN, 2 choices depending upon my last 6 VIN.

I include all this info to be thorough & perhaps save someone else some time in the future.

So, this “Ignition coil -- 2 different ones depending on VIN!” question is solved. I know I have a 4 PIN LNE1510AB ignition coil.
I can buy at my local dealer for $167 (Not worth trying to purchase from a MI Jag dealer for $153.) I can buy new from eBay Captain Jaguar’s Cathouse for $132.25 + $7.90 S&H Total = $140.15
I know I can buy some type of Ignition coil with 4 pins from many online parts web sites for approx. $130 but they use different numbers so may be aftermarket despite any claims that it is OEM. David was kind enough to search & list many eBay coils (used) but, they all have different numbers. I imagine that is the cheapest solution & may well work just fine. However, I do not know what causes a coil to fail. My car is 10 years old with 51K miles & I am experiencing my 2nd coil failure. When will the other 8 coils fail? Who knows? 6 months? 1 year?, never? So, I will not buy used ones.

Steve

To get access to the coils on Bank 1 (right side of the car) just undo the "snorkel" and the top of the airfilter including the MAF.
That would be removing two 10mm bolts (located on the top of the throttle body housing), opening the 4 clips around the air-filter housing, undo the breather hose on the valve cover housing (it is just clicked on, to remove you have to squeeze it an pull it off) and of course the electrical connector of the MAF. Now you can take off the whole assembly.
Now you have fully access to the six 8mm bolts of the coil cover. Remove them and remove the cover. Unplug the defective coil, remove two bolts and exchange it.


Good Luck!


David

P.S.
Nice find with the invoice! :icon_wink:

Thanks again Dave.

How Do You Test an Ignition Coil??
 

Can anyone tell me how to TEST an ignition coil? How do you know if one is bad? I know about rough idle, etc... but is there a standard test for these things? :icon_shrug:

Thanks,

SirJag

Hi
Rock Auto Parts.com is selling Jaguar XJ8 4 pin ignition coils for $66.79 (BECK/ARNLEY Part 1788363). That would be about $75 with shipping. There is also a Rock Auto Parts 5% discount code (51541254271936 put in "How Did You Hear About Us?" shown on shopping cart page) that brings the cost down to about $72 shipped. That is more than 50% lower than the Jaguar Dealer's price.

I have a 2001 VDP and held the coil in my hand. Mine are 4 pins, if that's help to anyone.

SirJag

Coils are difficult to test off the car - its easier to switch them and follow any problems.

If anyone orders an aftermarket coil (Say from Rockauto) be sure to post who actually makes them and the manufacturing location.

I have had no problems with the aftermarket coils on the few I have replaced on my company cars. Two on a Ford V6 a year ago and just recently - two on a Lexus. All were made in China.

Guys- This just ain't that hard. Aj26 engines have two wires and Aj27s have four

Well the suckers aren't cheap (to replace them ALL) so rather than replacing them all (the idle is rough and all plugs were changed... new timing chains done by prev. owner... new breathers... plus some more work already done) my mechanic--a Jag specialist--thinks it's an ignition coil making the idle rough. I need to have it checked to see which cylinder isn't firing and then I'll change THAT coil.

SirJag

SirJag .....I'm not suggesting that you replace any coils -- I certainly would not replace all of them! The best way to check the coils (and everything else) is to have the car connected up to the proper diagnostic tools and have a look - sometimes paying the $200.00 is the cheapest way to go.

To the original OP -- its a shame you have had a problem with getting the proper coil information - some parts guys are better then others.

Since Jaguar has no history of major coil problems -- I'm not sure I would be in the replace all camp ......... and finding a low mile OE used one would be a good way to go since I don't see any information on the reliability of the aftermarket ones.

Hi
I went on BECK/ARNLEY website and found that their headquarters is in Tenn USA. Their ignition coils (Part 1788363) are manufactured in China.

I phoned them and their customer service looked up the part number and told me that all of their regional warehouses are out of stock on this part number.

It will probably at least 3 to 4 weeks before their distributors receive their portion the 158 ignition coils that will be available. They have sold 58 of these coils within the last 2 months.

When Advance Auto Parts get them back into stock (their price is $85 plus tax) the net price would be $65 plus tax with promo code A123 ($20 discount). This discount is still in effect. I checked with Advance Auto Parts online chat box.

BECK/ARNLEY customer service person was very nice and polite and helpful. Also had very high class concert music to listen to while she found this information to give to me.
