Common Problems with the Jaguar XJR and the Reasons behind Them
Sold under the British Jaguar marque, the Jaguar XJ designation that was launched in 1968 was used for a series of luxury saloon cars. After going through a lot of style and performance enhancements through the years, the automaker came up with the supercharged Jaguar XJR in 1994 along with the production of the X300. Being the first supercharged road car that was manufactured by Jaguar, the XJR has instantly earned compliments for its hard-hitting performance. However, there are still some things car buyers should take into consideration when choosing the Jaguar XJR. Here are a few things to take note of before buying one.
According to consumer reports, the Jaguar XJR's transmission oil is synthetic. Although Jaguar claims that the transmission oil does for the XJR does not need to be replaced, expert technicians highly recommend replacing the automatic transmission oil with a new Jaguar-approved fluid for every 60,000 miles.

Car owners have also noticed chain problems on the Jaguar XJR's V8 engine. The chain tensioners that are made of plastic have a tendency to fail prematurely and cause serious damage to the vehicle's V8 engine. This is a common problem that can be easily detected by the noticeable noise that the engine makes during a cold start or while idling. This noise is usually accompanied by a rough or uneven engine idle. Replacing the old components with new and improved ones fixes this problem with the XJR's engine.
Fuel system and gasoline
Consumers also reported problems with some replacement fuel filters for the Jaguar XJR. Because the connectors on these fuel filters were not made to the manufacturer's specification, the o-ring in the fuel line may not seat correctly and cause an inadequate seal at the connection. This inadequate seal may lead to a fuel leak and even fire if an ignition source is present.
Another problem that consumers have encountered with the Jaguar XJR is its loss of power during acceleration due to a problem in the electrical system. According to consumer complaints, the vehicle goes into "fail safe engine mode", loses power on a down grade, and will start again. Car owners have experienced these fuse, circuit breaker, and ignition issues with the 1998 to 2000 models of the Jaguar XJR.
I was about to exit the neighborhood parameters when my Jaguar XJR suddenly stopped. I turned the key and held it for at least ten seconds, but my car won't start. It would not even crank. A few of my neighbors helped me bring the car to the side so it won't become an obstruction. What must be wrong?
There are relatively four major requirements for an engine to start up—sufficient cranking speed, adequate compression, enough ignition voltage, and designated fuel mixture. You are likely to encounter problems if any of these start acting up. For you to be able to pinpoint the source of the issue, you should be able to analyze the situation you are in. If you have been noticing unusual noises and slow cranking prior to what you have experienced just now, then it could be due to a defective starter, battery, or cable. A charging battery problem could also be the reason behind. If at some point your engine cranks but does not actually start, then it could be due to lack of ignition, fuel, or compression. But if everything has been going on smoothly and in a wink of an eye stopped running, then you might have to look into the fuel pump, overhead cam timing belt, or ignition module. You'd better bring your Jaguar to the nearest service center for an appropriate diagnosis. That way you would get the best assessment.
For a week, I've been experiencing the passenger door indicator coming on and staying on during the entire drive even when all the doors are shut. What must be the problem?
It could be due to loose connectors at the passenger junction box. The switches for these are built into the boot latch and door strikers, and the connectors could get displaced due to the car's movement and other factors. If you are knowledgeable with how vehicle wirings work, then you can check them out yourself and simply tighten how they are attached to one another. You can plug in loose connections and test if the indicator would not stay on when the doors are shut. But if you know nothing about it, better consult a service technician, who could properly assess the problem, and apply an immediate solution.
I own a 1998 Jaguar XJR and I've been noticing this loud noise that seems to be coming from the supercharger pulley. Could there be a problem with the supercharger? If yes, should I have it rebuilt?
That rattling noise you're hearing could be an indication of a worn-out supercharger coupler inside the nosedrive. To be able to confirm it, release the belt tensioner and remove the supercharger. Then, rapidly turn the supercharger coupler back and forth using your hands. A worn coupler would give you that sloppy feel, meaning there is no resistance caused by the weight of the spinning rotors. Hence, that should be immediately replaced. Also, another thing to look into is the bearing. Bearing issues can be confirmed if there is no more roughness or grinding as the pulley is being gently turned. It is relative that you think about getting a replacement right away.
