Some weeks back my XK8 experienced uneven running for a short time and then resumed back to normal running. When the misfire occurred, the dashboard displayed – ‘restricted mode’. I have since changed all the spark plugs and initially the car ran well but since then the misfire has returned. With my MK2 and the older Jaguars, it was a question of working backwards from the plug - to the plug cap - to the plug lead and then to the distributor cap (points and rotor arm).
With an XK8 with 8 ignition coils it is not that easy. Therefore, at a loss, I took the car to my local independent Jaguar specialist who then ran their diagnostics on the car and the result was that one of the 8 ignition coils had failed. With my car’s mileage at 90000 miles I decided to replace all 8 of the coils. The ignition coils are readily available (see below) and the job is quite straightforward for the DIY mechanic. My XK8 is now running great. The diagnostic check using the Autologic system really helped save a lot of time, head scratching and potentially costs. These modern Jaguar XK8 / Jaguar XKR cars are generally reliable but with their advanced electronics it makes sense to go to the experts to get the car back running smoothly on all 8 cylinders again.

Jaguar XK8 / XKR Window Memory Loss
I wanted to quickly add this post as I have just managed to start my Jaguar XK8 after several weeks layup in my garage. However the driver and passenger electric windows have lost their memory due to the battery having lost a lot of charge. In my case due to lack of use of the car but this could also be indicative of a failing battery. If this happens, the windows will retract slightly when a door is opened but won’t shut completely when the door is shut !. This is really frustrating when you come to lock up the car and there is a 1.5 inch gap !! – not great when it’s raining which is often the case here in Scotland therefore I thought I would post up the reset procedure.
Jaguar XK8 / XKR Electric Window Switches
Sitting in the car with the ignition on, press the drivers side window button to the down position and hold until you hear a soft ‘click’. Then press the window button to the up position and hold until the glass has fully sealed at the top of it’s travel and again wait until you hear the soft ‘click’. Repeat the operation with the passenger window.
If you use the car infrequently as I do and as there is a constant drain on the battery of the Jaguar XK8 / XKR, I suggest the use of a battery saver device. If the battery is allowed to fully discharge then there is the risk that the battery will fail completely and not hold power on a recharge. This will even apply to a new battery. This can be frustrating and costly in having to replace the battery.
A quality battery saving device simply attaches to the battery terminals and connects to a mains socket. They will trickle charge your battery and will significantly prolonge the life of it. Also following limied use, your XK8 / XKR will then be ready to burst into life when starting up.

Just in case your battery has failed completely then you will need the size 017 to replace it. Also consider a quality battery saving device. Click Here for our Battery Charger / Conditioner Review.
