    x type diesel turbocharger electronic wastegate actuator

    Hi, can anybody help with the following problem.
    I have a 2005 x type 2.0 diesel with the euro 4 engine fitted.
    The turbocharger electronic wastegate actuator is faulty.
    I have spoken to my local Jaguar dealer & they can only supply a brand new complete turbocharger for an obscene amount of money. They know its a common fault & have replaced more turbochargers than they care to mention.
    I have spoken to several Jaguar specialists & Turbocharger repair centers all around the country & keep getting the same answer - Its not available - but everyone seems to know its a problem.
    I just cannot believe no where does a replacement - the unit can be removed from the turbocharger within a couple of minutes.
    The main turbocharger itself is all ok, the vanes on the turbo move freely & all the voltages appear ok. The fault has progressivly got worse & the actuator just stops working when it gets warm.
    If anybody can help with where i can get it fixed or buy a replacement i will be really grateful.

    If it progressivly gets worse as it warms up, it may be ok and you just need to clean the mechanism?

    Hi,
    thanks for the responses so far.
    Well I've been talking to various people this afternoon & it seems im in a no win situation.
    Garrett who build the turbos apparantly are the only people who get supplied the electronic wastegate acruator assemblies. They are not made available to anyone else.
    These electronic actuators are basically a mini ecu that is assemblied to the turbocharger & then plugged in & coded into that specific turbo. The eccentric vanes are operated & the ecu burns into its memory the stop start values etc.
    Therefore even if i did get hold of another ecu actuator of another identical turbo, the chances are it wouldn't work correctly.
    Therefore it seems im left with only one option, i've got to buy a complete new turbo.
    A couple of places i've spoken to know all about this problem & are currently researching a solution but they are unable to tell me when this might be.

    Im just totally amazed that with all the current technology about there is no one out there that has ever come up with a solution to this.
    Im sure there must be many Ford owners experiencing the same problem as this engine is fitted in both vehicles.

    Oh well i'll just have to start pricing up new turbo's !

    Hi,
    came home from work one evening, left car for about 30 minutes before going out again. Started car, went to pull away & noticed glow plug light was flashing on instrument cluster. At same time vehicle lacked power & would not rev above 3000 rpm. Tried switching vehcle on/off several times but fault still occurred. Following morning vehicle drove ok. Couple days later went out in vechicle, parked up for 10 minutes, came back started car & fault occurred. Since then the fault occurrs all the time, When started from cold vehicle ok for couple of miles then as soon as warms up the light starts to flash & goes into limp home mode.
    Went to my local independant Jag specialist who plugged it onto diagnostic laptop - fault code P0238 found in engine control - Turbocharger boost pressure sensor fault. They had seen this fault before & it was basically a known fault to them. If you watch the turbocharger actuator linkage rod when you start the vehicle you should see it move & settle down, also when revving the engine it should move dependant upon engine load etc.
    On my vehicle it didn't move when the fault occurrs. The vanes on the turbocharger were checked to make sure they moved freely.
    As already mentioned it does seem to be a known problem if you speak to any Jag specialist or main dealer as they all report many replacement units being supplied & fitted.
    Hope this info helps..................................

    Plenty of remanufactured mondeo/X type turbos on ebay so their supply mustn't be an issue. Prices are also about what I paid for my laguna turbo about 3 years ago although I dare say you won't want to fit it yourself.

    Did the garage give you a price for the repair?

    The price quoted in the Ford Ecat system for this turbo is £902 which I agree is a lot!! The high cost is partly due to the fact that the complete turbo assembly includes the exhaust manifold.
    I note that your car is a 2005 model so it can't be that far out of warranty.
    Not many people know that Ford's warranty system includes an after-warranty stage called "policy" where under some circumstances they will make a contribution to the repair costs if, for example, it can be shown that there was a manufacturing defect. The contribution decreases with age. I don't know if Jaguar operates a similar Warranty & Policy system but it might be worth asking, especially as the offending part is a Ford part. I know that Ford do replace complete engines for Jags under this policy. Apart from that, have you tried cleaning out the waste-gate mechanism as suggested in another post? The actuator is not a heavy-duty device so it would have difficulty in operating correctly if there is any obstruction of the linkages etc.
    Good luck.

    I hope I'm not off-topic. I had the exact same simptoms on another diesel engine and it was the EGR valve. Cleaned it and worked ok.
