and I posted this under my brakes- but again- not one problem in 50k miles and this below is all happening? Its got to be all related-
-------------------------------------------------------

again stated i love (loved) this car- 2009 XF loaded- non s/c
50k trouble free miles (squeak in sun roof - that it fixed)
never had 50k trouble free miles from any vehicle

Now Im at 56k and it seems like its the jags we read about years ago.

here we go….

1)This AM?? Start car "GEAR BOX FAULT"- i wait a minute drive away its gone - never saw it before.

2) Car is RUNNING 3x i got the EBS "turn on car in next 5 minutes or audio will be shut down"- the car IS RUNING when I see this -audio is off- 8 month old jag installed battery -had it load tested etc - its supposedly perfect.

3) TPMS still goes round and round with new tires. Had each sensor cked all read fine. Then I read this and went to local non jag shop

it was loose! we snapped back into place and then we found this

2009 JAGUAR XF Parts - Direct JPLV Porsche Parts.com

part 7 was just swigging not attatched- we taped it up
problem still exists….

Brakes- being in a non mechanical guy- I'm going back to a dealer-
i have found they will indeed negotiate

But seriously this is totally out of hand-
As god is my witness i would pay up the big $$ if I thought one of these dealers were competent.
for TPMS? they will change the Module- I'm sure of it - when i was there I said "i pay the 400 and the sensors still not fixed are u going to give me my 400 back??

Really at my wits end
im not bashing Jag- I'm venting the aggravation of non qualified guys who have the truly only correct diagnostic tools but dont know how to use them or just want to rip me off.

I believe its like my laptop- its got be wiped clean and reinstalled.
===
I saw "GEAR BOX" i went into BMW dealership 640 w M appearance package.
sales guy is bragging - i say - "the dash- sides- wheel- they are vinyl right?
I then say - come here - sit in my car
he goes nuts over how the vents open B&W sounds - etc etc etc all leather...

I sat in the jag in 09 and said "done" like immediate
I sat in a 82k BMW and thought - PLASTIC ?? ALL PLASTIC????

I NEED HELP
ONE EXCELLENT MECHANIC

THIS IS NOT ENGINE MODULE
THIS IS SOMETHING MUCH SIMPLER THAT THEY WILL MISS.
BUT NOW THEY GET THE "SHOT"
WORST CASE IS $130 FOR "DIAGNOSTIC TESTS"

feel like asking to borrow one of their older batteries for a week see if it makes a difference

tks for letting me let off steam

 

i also neglected 2-3 months ago
kept getting error code
secondary fuel pump failure that just magically went away…..

 

I've seen the gear box error but for a split second and only on occasion.

All those glitches might point to a battery issue.

 

Sounds like battery issue to me!

 

i had the new battery checked out -
load tested or whatever they do by a guy who specializes in jags and he said it was working perfectly…


i still feel its the battery…

so jag will get the car charge me $130 for diagnostics
they win
and I dont trust anything they say

 

All those random error messages are more than likely related to the same issue.

Swap batteries and see if the problem goes away. That'd be the first step I'd take.

 

Battery or el connection somewhere central. Maybe intermittent charging issues. Batteries can be bad even from new and still pass the battery test, intermittent internal fault is the cause. So swapping could be a reasonable place to start. However that needs a diagnostic tool to "recalibrate" the battery monitoring sysstem (BMS) unless they have changed the software to include a learning function. However, the only error message you should see then would be the battery. Everything else should be fine.

When they run the diagnostic tools get all of the DTCs stored and post them here. I would guess some would be either voltage related and/or CANbus related (internal communication between modules). But primarily you should get BMS related DTCs.

The Jaguar diagnostic system is basically the Ford IDS with add-ons. So any Ford dealer should be able to read DTCs and in fact program most modules. An alternative is any reputable specialist (also non-Jag) who uses the AutoLogic diagnostic system.

Happy hunting.

 

the battery is - 6 months old- i have given up and tomorrow I go to jag.
BUT before I go today I went to a Pep Boys where they do Battery /starter /alternator checks.

ON THE WAY OVER THERE I GET MESSAGE WARNING- SHUT DOWN ALL AUDIO ETY- AND AGAIN CAR WAS RUNNING….

SO PEP BOYS RUNS 1/2 HR TEST…

Results
Jag battery is rates at 820/My battery is LOW 750 voltage 12.2
computer spits out "battery is good but state of charge is low. Check for proper charging output and excessive key off draw.
(which means when i lock car go to sleep something electrical is still running drawing power) and my key is literally 15 floors away form car


Starter Test - "cranking normal voltage 11.020

Alternator Test - "no problems"
no load 14.3
loaded 14.230

so jag wins- I go tomorrow to be ripped
I hope no one minds - I'm going to start new thread about battery drawing in sleep shut down mode

tks

 

went to new dealership…
sall tpms antennas were lying on side
fixed
all checked on but one code
took seat out checked module zero corrosion

he cleared codes - said if it happens again bring it back i want to see code -
then we decide if I not them order the module and receiver

he has never seen a receiver fail ever

i was actually allowed to watch him work 2 hours testing 65.00
and i wake up =
all tpms are still lit up circling

i just really hope Merriam or Guadin are truly OEM parts

 

just replace the module....

 

you probably would have been right in replacinng module
but the new dealership SHOWED ME the wires where the antennas fell-
said do not order for a few days
if it keeps going on - oder it

it finally stopped
or learned.

my problem is not w car i love/loved it
just mechanics who truly know nada

 

mine was doing the same thing for 3 days and then has just stopped....weird...last time, I replaced the module and all was good. just so you know, virtually every European car has crappy TPMS.
