Jaguar XK8 Trip computer - fuel usage, mpg, average mph etc - can't toggle through this info using end of indicator stalk switch. Could it just simply be the stalk switch is faulty or is this a more commonly known fault elsewhere in the jag's electronics? Thanks.

Friend, your situation could be taking place on ANY vehicle, not just the Jag. Anytime this type of thing happens, no matter what it happens to be, ALWAYS go directly to the ground. Check ALL your ground connections on every ground wire you can find, and the ones you can't find, under the dash that are held to the firewall and any metal braces by a simple little screw that could be loose. I find this stuff is a LOT like connecting a trailer to a vehicle for the lights. Sure it's wired properly, you know what your doing!!! Then you check and tighten the ground wires between the vehicle and trailer and it now works. ALWAYS go directly to the ground connections. That's normal procedure. If it still doesn't work, get out the test light and start checking for power. But then your not doing trailer lighting. Get yourself a wiring diagram and check it closely.

SOURCE: Adding coolant to a 1998 Jaguar XK8

if the coolant light is on or comes on when driving you MUST let the car cool down at lest 1 hour before doing anything, after this cool down time lift the hood [u.s.a.] or bonnet [uk] looking from the front of the car on the right hand side towards the back of the engine compartment is the coolant header tank,about 5inch square black in color [u.s.a.] colour [uk] with a large screw top and some rubber pipes coming from it,this should be topped up with coolant right to the neck of the screw cap when you remove the cap to top up the coolant unscrew it slowly as it may be under pressure you don't want hot 212F[u.s.a.] 100C [uk] coolant in your face do you.good luck.

SOURCE: Had the EGR changed on

Changeing the egr valve will not affect the engine management .you do not have to resett it. but the more miles in the trip the less acurate as it only a estimate    D

How to reset trip meter to zero for every journey on jaguar s type and also where the button to reset is please?

The two buttons that control the trip options are on the dash adjacent to the hazard warning button. Press the TRIP button untill it shows a small A or B in the top left (say average mpg) then press the upper part of the toggle switch marked RESET/CLEAR and hold it for about four seconds, this will display A or " B resetting" depending on which trip you are currently in, then everything on that trip is reset to zero (mileage/mpg/ave.speed etc). I use A for the full tank recording and B for individual journeys that I wish to record.

1999 Passat V6

The previous post is untrue! MFA means MultiFunktions Ansiege (pronounced AAN-zeeguh).
This is a German- Americanism for Multi-Function Indicator.

The MFA displays the time, time driven since the ignition was started, miles driven since the ignition was started (trip miles are displayed under the odometer), miles per gallon, average miles per gallon, and outside temperature. I think that's it. If you click the little button on the underside the wiper switch, you can toggle between 2 different trackings. If you HOLD that button, you can re-set the avg. mpg's (but not the current mpg's, they are calculated every 30 yards), time driven, miles driven. Contrary to the previous poster's solution, it does not actually indicate anything is wrong with your car! (but they were right about scrolling through the indications with the side rocker switch) the malfunction indicator is on the cluster, it is a little engine block with a lightning bolt through it. It usually means you need an oil change. If it blinks, you have a catalytic converter problem. Hope this helps.

There is no indicators working on the car the message trip computer system is stuck on the same message and and cannot toggle between average speed etc. the message and dashboard lights are very dull. the...

The hazards most likely still work, but when they key is out, it won't flash on the dash, but will outside.

As for the indicators and trip...could be either a steering wheel module to a turn signal stalk issue.

Were you having problems with the turn idicators acting weird before?
