This car has a high output lamp system. Start by checking all your fuses. This system works like a florescent light and has a ballast that fails,troubleshooting these systems requires knowledge of high voltage systems. You may be better served taking it to a Jag. knowledgeable professional. In this case it may save you money and injury.

Check the Wheel Bearing and the hubs as those models having common problem on the Wheel bearings as well as the Bearing carrier. Try to investigate ASAP as the Carrier might get broken and will give you big damage.

Yes batterys can come apart inside. The plate breakdown and drop into bottom not allowing charge anymore. Low charge can do alot of weird things to you jag. Replace the battery and when you do have them check alternator charging ability while your there. Almost all auto store will do this for free.

I'm sure you mean Volts not amps. That ALT. has an internal voltage regulator when they get hot they are known to fail to be sure have the carging system at a garage it runs about $50.00 but better than buying an alternator that may not be broken.

There is a manual way to close the roof top latch.
Have a look near by the latch over the mirror and you'll find a little plastic plug to remove so to have an access to the locking key

Having a restoration shop and running several newer Jaguars I have seen similar situations. Intermittent multiple errors such as these can be caused by a low battery (or corroded connections) that "fool the computers". Also had a '99 XJ8 VDP have exactly the same issues over several months. Issue was a manufacturing fault in the sensors on the throttle body that caused the "limp home" mode - usually in stop and go traffic. Jaguar had an inspection and recall on the throttle bodies but that vehicle had gone through 3 different Jaguar dealers for service and none looked at TSB/Recall or performed the necessary checks on the throttle body. Tried cleaning the throttle several times (per Jaguar TSBs) but no change. Had to replace throttle body & problem solved (over 30,000 miles since then). Recommend making sure all air connections to throttle are clean and open and cleaning the throttle area to see if that helps.

On newer Jaguars (and other Al bodied cars) similar problems occur when the "ground" connections to the body become poor (usually through corrosion but sometimes through collisions). Connections may look perfectly normal but have high resistance. Careful when working with the connections - the posts are usually very loosely fastened to the bodies. Good luck.

you may try adding a engine oil flush follow the instructions on the container if the lifter is blocked that may help but that engine at that model/year suffered with worn nicosyl coated liners which made the engine poor starting/noisy unless it has been reworked with cast liners

Is it the PSI specs good {30PSI?} If not u have to start w checking 4 vacuum leaks, oxygen sensors, get emissions test to get all other emissions read (HC, NOX, CO) All the readings will give the tech a path. U have to have the right amt of fuel going into the pump & regulator to get the right PSI too. Clogged exhaust? The possibilities go on. Good Luck

Could at either plug(corrosion) Most wires break close to the plug, Check voltage a couple inches back. Unplug it(if you haven't already) check it. If you have voltage at the brake switch and a couple inches back(probe the wire) nothing at the Shifter solenoid. I would run a new wire to it. Way easier than removing the console and dash to find the short. If you have other problem, I would be looking at the fuse panel .

Possible bad wire in motor so it opens up and stops motor after heating.
