Valvetronic internal fault and servomotor power limited

the limp mode operates for both the engine and transmission major faults
run the fault codes to find the problem

Your vehicle seem to have gone into limp home mode. You need to have the fault codes pulled to know what is wrong. Limp mode lets you get home but limits engine output function.

You need to have someone very experienced with these cars look at it and give you a price on the repair.I am sure there is a european repair facility that has been in business for several years close to you.Whoever told you you needed a "valvetronic" would have given you a price on the parts and labor to install if they knew what they were talking about.Do not let someone guess at what is wrong , parts for this car are expensive and a good diagnostic will well worth the money.Sometimes mechanics will say you need a part that they dont install to get you to leave so they dont have to admit they have not got a clue what is wrong.Any professional will supply the diagnostic , the labor , the parts and a warranty on all .If someone sugests any other way I would be suspitious.Good luck! Let me know if I can help you find a shop.

jaguar x-type 2ltr diesel 2004 the glow plug warning light flashing, was told dirty fuel on fault code all fuel changed and filters. No problems for 20 miles untill engine was put under power on high revs went into limp mode, warning light glow plug falshing again? any ideas thanks.

indicates a broken wire that controls the valve servo .solenoid operation
the battery could be a faulty voltage regulator

Check the ABS brake sensors in your wheels, if they are not functioning properly. It will trigger the computer to engage the ASC auto stability control light as the asc uses the brakes to assist in control. I will also engage the EML engine management light to slow the rev point to limp mode

Hi
Air flow sensor could be a problem.
Every time EML comes on the car computer will put the system into limp mode. To avoid any further damage to the engine.

once switch off, isolated and re-start will re-run the program and clear it temporary.
Ideally you need to get the car plugged in to a Diagnostic computer and see what fault code are stored.

Thanks

What is limp mode, and it is MiL light( mal function indicator light)it is not EML. Please specify so i can help

the engine control unit has detected a fault light illuminated which in turn reduces ability to gain high revs as a damage limitation exercise , known as limp home , car requires diagnostic computer to check fault codes to indicate faulty component causing ecu to go into limp home mode

Code 24 is a vehicle speed signal sensor fault, the sensor most likely does not provide a useable signal until about 25 MPH, when the computer doesn't see any signal after that speed it turns on the light. Make sense?
