  • My light is on and my dealer told me that he "think" it could be gunk in the engine causing it.

    I can't understand that because I change the oil every 3K.

    The car only has 45K on it.

    Any thoughts? I heard that Lexus is having problems because the oil is turning to a gel.

    Well sludge should be readily diagnosable by just popping a valve cover off. The dealer should get on this right away.

  • My 2000 S-Type just had an engine light at 76,000 and it was leaky gaskets for the (plastic) intake manifold. Replaced the gaskets and it's fine.

    There is a vacumm elbow under intake that will colasp and have to be changed by taking off intake. Not as bad as it seems. but first listen to engine at idle for a hiss

    My 2000 just went into "Fail Safe Mode". Luckly my wife was not far from the house. She limped it home. Does anyone know what the cause of this could be? The nearest dealer is 84 miles away.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,967
    This could be triggered by any number of problems. There's no one cause for "limp mode" Did the MIL (Malfunction Indicator Light) light go on, on the dash? You may need to flatbed it to the dealer.

    I don't know, I'm stationed overseas and she said there was a engine symbol that was yellow and then turned red. When that happened she said it said "Fail Safe Mode". Sorry I can't be more specific.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,967
    Yeah that's probably it. I sure wouldn't drive it that way. The engine can shut down for any number of reasons....might be serious or it just might something like low on oil in engine or transmission....or a bad sensor giving a false alarm. It's hard to say...but, obviously, the system has shut down to protect itself....that's why they install such a thing rather than just a warning light....they want you do stop driving it...

    Hi!
    I have a 96 XJS convertible which I am sorry to say I have to sell. The car as approx. 100,000 miles and runs/drives very good. However the "check engine" light stays on and has stayed on for quite sometime. Now I have had the car checked and without spending mega bucks the local shops and the dealer have told me they cannot find an engine problem, must be an electrical problem.

    Can anyone help me on how to get this stupid light to stay off?
    Thanks
  • My 2001 s-type has a hissing sound still coming from around the intake manifold area. I replace the vacumm hose connectors that were cracked, replaced the top 6 ruber caskets but still the hissing persist and at ideling it dies. Is there one who may have an idea what could be the cause of this? or a site to display the diagram of the intake system?
  • I have the exact same problem with the hissing and idiling eratic then dying if you found an answer or anyone knows I would appreciate some help. I have the plenum off I guess I'm going to take the fuel intake off and see whats under there.
  • your vehicle must be a 3.0 litre and the hissing is not coming from your intake gaskets but coming from a hose that is underneath your fuel rail.

    the rubber hose is connected to your oil seperator. it not that easy of a job to do so i would take it to your nearest jaguar dealership.

    good day to you :mad:
  • Thanks for the info but i took it all apart and the hose was collapsed, so I replace it and now it runs great. I actually thought it was easy and would not recommend takin it to the dealership so they can charge you 400 in labor for a dollar hose. I am used to working on the xjs and xke
  • My engine went into Failsafe Engine Mode with an amber light and after 2 miles the red light came on and the car would barely move. I was able to pull it over to the shoulder, screamed, then waited about 3 minutes and the car drove normally as I took it into the shop. They said it was the accelerator pedal sensor ($400.00). this is one month after I've gotten a new engine, and two weeks after that had my transmission rebuilt...that's why I screamed!!!

    My light has always been on and they say it's from the gas tank not being shut right, or it's dirt in the cap...It's been fixed over 11 times and it's now been on for over 3 weeks...gong strong!!! LEMON!!!!!!!!!!!!!!!!!!
  • fflowersfflowers Posts: 3
    I purchased 2005 s type..From DAY ONE it's been nothing short of a nightmare..You name it..from the gas tank not shutting, the glove box broken, the fuel tank leaks, the automatic brake locks up and shuts off the engine while driving on the hwy in traffic!!! The engine light has been on over 15 times or more and it's now been on over 3 weeks!!! LEMON LEMON LEMON!!!!! Jaguar has been my biggest nightmare ever..GAUDIN JAGUAR IN LAS VEGAS NV sells LEMONS!!! Oh let's not forget the BRAKES that has to be changed every 6-10 months!!!!!!!!!!!!
  • where exactly is that hose located, someone said it was under the fuel rail and it was connected the oil seperator . i have the same issue with the hissing noise. and im trying to change it myself if i can find the hose
  • dryden57dryden57 Posts: 8
    take the plenum off then the fuel rail, there will be the black rubber connector hose that has collapsed. if you look by the mass air flow sensor there are 3 hose inlets the one facing back towards the engine is connected to ur problem, so either clog that hole to see if the hissing stops or run your hand back that plastic hose until it connects tl a metal u shaped hose in the back the rubber hose that failed is connected to the metal u shaped one
  • is the plenum and the fuel rail under the hood or under the car . what is the plenum ? would i have to change the hose from under the car when i find it ?
  • On a Jaguar 2000 S type 4.0, the Fail Safe Engine light has started to come on whenever I turn on the air conditioning. If I do not have on the air, the light does not come on at all. When the light is on it drives very slowly, but then picks back up after about 3 hrs after I have turned off the air.

    Can anyone give me give me an idea what to do....

    So you aren't getting a high temperature signal or an overheat warning on your message board?

    I think you need to have the car scanned for trouble codes first off and let us know what codes are stored. Autozone can do this for free in most cases.

    my check engine (yellow) light came on after my car sat in a torrential downpour saturday night. The car ran ok to about 40 mph and then it started hesitating/lightly bucking on my 55 mile trip home.

    Any help would be appreciated.

    I have three questions...LOL 1)Where in the world is the fuel filter? 2) Where is the transmission dipstick? 3)Have a problem starting the car after 20-30 minutes. Like it isn't getting fuel, then when it does start smells like it is nearly flooded.

    Thanks,
    Angie
  • Question number 1, The fuel filter is in the gas tank. 2) The transmission is sealed, there is no dipstick if you have to have this looked at the Jaguar dealer will have to do it. 3) You car is fuel injected, have the dealer check your ignition coils. Hope this helps. :)

    To All:

    Ignition coils were the problem. I replaced all six of the for $526. :shades:
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,967
    Did a trouble code tip you off on that?

  • rgroskirgroski Posts: 6
    When I brought the car to Autozone the code was a bad piston which tipped the dealer's repair service to mention to me that it may be a bad coil. It turned out that 3 coils were bad so I replaces all 6.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,967
    Yes people often think that the code tells you which part is defective but that is not true. It only shows you the circuit/system in distress. A mechanic's experience tells the rest of the story. Glad you solved it, hope it wasn't TOO painful. :sick:
