Don't fret Ken....

And just for further amusement, this is one of the few times I had to throw on a uniform so I could wake up a bad guy early one morning and thoroughly ruin his day 😀😀

If you happen to see this mechanically competent, heavily armed girl knocking on your door in the wee small hours, don't run...

(Picture from Australia... it's the right way up for us)

 

. . . and I thought I was the one with a weird sense of humour!!! Hey Donna, great photo and I bet your upside down approach has all the bad guys fooled, eh? Congrats on your important role . . . and especially on your brilliantly inspired choice of Jaguar saloon (don't your love that word, saloon).

Anyway, I now find I made an "oops" . . . one that will not change resolution of your issue, but could expose all the rest of us to same weird problem. Jaguar did not move the GECM in later cars, as I incorrectly said . . . they renamed it . . . much cheaper and, except for the cost of reprinting labels, allowed them to continue using same part in same location. Thus, the General Electronic Control Module (GECM) became (tadah) the Front Electronic Control Module (FECM).

And guess what? The FECM retains all the functionality, including the Oil Pressure Switch previously noted for the GECM. Finally, I have attached 2 pages from JTIS for your MY2002.5 S-Type, which you can print, but suggest you download the full deal from the Sticky "How To . . ." at the top of the threads here.

Gosh Donna, I hope that reprieves me from a 3am tap on the door . . ? (LOL)
Cheers and best wishes,

Ken

 

Thanks Ken.

Mine is actually an MY2003 X202, I'm guessing that might make a difference?

 

So your avatar picture is upside down?

Nothing much gets past me.........

 

From here my avatar pic is upside down, deliberatly done so as not to confuse the northern hemisphere mob. We're used to seeing things that way ;-)


(OK, so I posted an upside down pic and tried to make an excuse rather than fix it... You got me...)

 

Nope . . . all's good by using the MY2002.5 for which we must remember to read "midyear 2002" and that does not mean June/July . . . it means mid production year. Both the UK based manufacturer and external markets like USA & AUS interpret model years differently. Yours is quite correctly listed as MY2003, but note its build date of Sept '02.

Generally viewed as critical is the VIN ending M45255 . . . below, are the basket of S-Types with the U-shaped centre to the dash console area . . . and beyond, like yours some 28,000 vehicles later, are those upgraded in so many body, trim, instrumentation, powertrain and mechanical areas.

Best wishes,

Ken

 

Just add more trivia and making it all confusing, I believe that MY universally means Model Year and not Mid Year.

The 2002.5 term was used only in the UK to denote the redesigned vehicles they got about 6 months earlier than the ROW.

 

Yes.

And also I've found GECM = FECM = FEM used in various places. I think some of the jag tech writers just picked one term or the other but failed to agree with others on which!

Definitely a weird fault BTW.

Puzzling pic that appears neither right nor wrong way up...

 

Quite correct Mikey and I agree, I conveyed the wrong impression . . . in speaking of "mid year", I was referring not to the "MY" but to the ".5" attached to "2002". By that usage, "2002.5" implies mid year . . . and to make it even more confusing, other models and years of Jaguars, as you know refer to ".25" and ".75". My personal favourites are the 2008 S-Types and STRs (albeit most are correctly known as MY07) . . . all I have seen have build dates of 2007 and we know that the former S-Type assembly line at Castle Bromwich was pouring out XFs throughout February to meet March 1 launch.

Countering any confusion, VINs are unambiguous.

Cheers,

Ken

 

I've been unsuccessful in recreating the problem while instrumented: https://www.jaguarforums.com/forum/s...1/#post1677271

 

Guys,



So far no success in locating (or recreating) the problem. I have a new pressure sender / switch which I might just swap over when next I drain her ofher vital fluids and replace them with new.

In the interim I could just limit my choice of passengers so I’m not restricted to heavy vehicle routes...


Donna :-)

 

May be a chafed wire/harness and it's currently not causing trouble. If it is that... it'll do it again at some point

 

Hey Donna, please update us when next you and friend go driving. The cause has kept nagging and I, for one, am uneasy at any fault that "fixes itself".

Cheers,

Ken
