    1. The engine coils on the V6 petrol engines are prone to failing early. Symptoms include rough running . This is quite expensive the rectify as the coils all need to be replaced.
    Water get into the coils between the scuttle panel and the windscreen so the joint needs to be well sealed. If it is not you will continue to have problems.\

    2. Rough running can also be caused by a leak in the vacuum hose above the inlet manifold.

    3. The boots also leak in this model (another well known problem) and when water gets into the electrics you will have other problems.

    These cars do not have a good reputation for reliability and repairs are usually expensive. So be aware of this if you keep the car.

    These are well known problems with this model.

You have an exposed electrical source and/or a fan belt that is slipping when it get wets. When the belt slips, voltage drops and ignition is very voltage sensitive. Check you fan belt if it seems loose and or glazed (smooth)

This would appear to be a immobiliser fault? Try a manual start - do not use fob, open door with key and immediately put the key in ignition and start the car. Using this method - when you open the door you will hear a chime this is counting down to starting the alarm. This method can sometimes get around a fob/immobiliser fault. If this makes no difference then you need to get the car checked at a Jaguar dealers for the security system. - good luck.

Hard to diagnose your problem from my laptop but if it shakes in the morning I would asume a cylinder or two are misfiring. I would pull the plugs out and see what the engine is doing. Not an easy task as the manifolds have to come off to get three of the plugs out. Also do you have the check engine light on? If so the codes will tell you what, if any, cylinders are misfiring. Possible lazy coil packs ( one for each plug ), worn out plugs, etc.

Flashing Check Engine Light


Hi, flashing check engine light in car means a lot of things which can be related to any part of the car. So for you to detect what the exact problem is, you have to take the car to Auto zone for the car to be scanned after which a code will be retrieved and interpreted to detect what the problem is.
When my 2002 Jaguar x type had the engine light flasing. I took it to Autozone and had the error codes read it said cylinder 5 misfire and something that had to do with the airflow.
With that the problem was easy to fix...
Take care

O.K. from what you just described- Miss fire on #6 and loss of coolant(it does not just disaper) I'am afraid that these two items are most likely related, along with the fact that it took along time to cool down. It sounds like the coolant is being lost thru#6 cyl thus causing the misfire and the overheating- which turns the light on. Sorry but i am afraid that you may just be spending a lot of $$ Take it to a mechanic and get a second oppinion first.
