Agreed !


As I suspected.



That would be very irritating

If there's so much confusion I'd just order the Jaguar part under the Jaguar part number.

Incidentally, curiosity having gotten the better of me, Jaguar's own knock sensor listings (see catalog listing in the link) make mention of "white'...but without clarifying remarks

If you're seeking an answer to this question......

So, is anyone can make sense, what is it and on which car it should be used?


............then knowing the origin of the number would be very helpful.

As someone mentioned it has the appearance of a Ford number. If it IS a Ford number then the next question would be "is it a manufacturing design number or a part number?", as those are two different things. A basic part design can carry a manufacturing number and then be modified to suit different applications by changing connectors or other small details. These alterations to the base design might result in several different part numbers....which may all carry the same manufacturing number.

In Googling I've also seen that sensor come up with grey and blue connectors as well. In all of these cases there would be manufacturer-specific part numbers as well....with Peugeot, Citroen, Landrover, etc all having their own scheme for creating and assigning part numbers.


All that being said....

If you're asking whether a part marked 48RQ-12A699-AB, or one being marketed as 48RQ-12A699-AB, is the right part for YOUR Jaguar, I can't say.

Which make it even more confusing given that this is not only color but the shape

BTW, AJ85676 OEM part for B bank in Canada is $180 and A bank AJ84433 around $80
Rockauto - $105 Canadian plus shipment but there is no way you can beat $30 Amazon's price

 

Until this happens......

who bought part only discover after mechanic lifted intake manifold on SC engine that this is wrong part?

In this case I'd skip the mass-merchandizers who know nothing about what they're selling and buy from a specialist.

Thanks for reply.

Well, for me it is obvious now based on connector type that this is not for 2004-2009 Jaguar XJ X350
or I would buy it in a heart beat. Then again, for adventures person it would be challenge to buy part,
play with connector, install it to see what would happen but... I'm not that person.

Just curious.
Could it be that knock sensor's part itself is the same for every car but different companies coming up
with something that makes their brand (beside part number) different like connector, for example.
After all, if you compare knock sensors, 90% of them look the same.

 

Funny you should mention but a few years back I went to dealer to replace cracked windshield.
Dealer order one from warehouse according to my specifications but when they remove cracked,
they discovered that my XJR windshield is heated type but supplier shipped them regular one.

For the next 5 days I was enjoying driving 2015 XJR curtesy of my Jag dealer.

 

Well, well, well... I think this post will explain that part number and application confusion
https://www.jaguarforums.com/forum/x...6/#post1204085
specifically last line of that post

 

It happens, yes. That's what I was referring to earlier.

I don't see any discussion pertaining to the part number confusion in that thread

How about I'll give you a clue
"Jaguar XJ (X350) Diesel"
"Jaguar XJ (X350) NA"
You have 3 guesses

There is some answer in the next post
https://www.jaguarforums.com/forum/x...6/#post1204094

 

I thought you were looking for answers regarding the knock sensor part number mystery and confusion. I don't see it in the thread/postings you are refer to. Maybe I'm missing something.

I'll excuse myself here. Your posting style is rather vague and I'm not interesting in being given clues and 3 guesses.

Carry on.

I have no idea why someone has their knockers in a twist, especially as they know all about it.

Are they complaining about Amazon, or eBay, false advertising? Do they expect Amazon, or eBay, to vet the accuracy of every tom dick and harry who advertises a part?

Is he French? (my mistake, just a random thought )

 

Maybe that would help
"Jaguar XJ (X350) Diesel" uses part #4R8Q-12A699-AB
"Jaguar XJ (X350) NA" uses part #AJ85676 and these 2 ain't interchangeable

@dalo in his post talking about his Jaguar XJ (X350)

My car is Jaguar XJ (X350) too.
Looks the same? Right?
The difference, 2 the same XJ (X350) Jags except @dalo owns Diesel car and my is NA
which means the same model but different engines, different parts numbers.

 

No they don't or I would learn that there is 2 XJ X350 Jags models whereas 1 of them is NA
and another Diesel and that 4R8Q-12A699-AB is part used in Diesel Jags and not in NA in
a very second post of this thread.

 

Your first question actually asked what a knock sensor is. AND on which cars either a knock sensor or this particular part should be used.
It turns out you know everything already, so what was the point you were trying to make?
I suspect there's a problem by way of English not being your first language. (or even useable in this case)(because you criticise people for trying to understand your gobbledegook)

 

Would you mind to point me where I'm asking what knock sensor is?

As to languages, I can speak 4 of them. How many of them you can speak?

 

Sure,
"So, is anyone can make sense, what is it"

I speak:
"Jaguar Owners Handbook"
"Jaguar Workshop Manual"
"Jaguar Parts List"
what else?
"Amazon Terms and Conditions" (if that was your problem)

If it was a Citroen, I wouldn't even go there

 

And you're the one who's talking about sentence structure? Really?

How come you don't mention very first paragraph where I'm talking about part numbers?

Or second paragraph where I'm pointing to part number

What about third paragraph? Maybe that one help you to grasp that this is about "part number"

And then in my last paragraph, even monkeys could see clearly, I'm continue talking about
part number and it application:

If I were you, I wouldn't sell myself as some linguistics stable genius.

 

No. I forgave the sentence structure. I was referring to "what is it", which was your first question.
The second part of the first question was "on which car it should be used?" I believe people attempted to answer that.
Part number was extensively discussed by others, you either didn't like the answer(s) or already know better, which begs the question of what exactly you were asking.

Since most of your other replies appear to be replying to yourself, enough said.

BTW I speak English. My wife speaks Hindi and Telugu, just in case I have to ask Tata Motors lol.
