hi get the codes read, it could be 1 of a 1000 things, otherwise its just pure guess work a good code reader or ideally jaguar ids/sdd to get accurate codes, faults and remedies cheers Joe

For a long life and easier way to protect the battery is to invest in a CTEK charger/conditioner. They are so very convenient to just keep the battery charged and in good condition. Best Wishes , John

To be honest I only managed about 45 mins at 73, got fed up of everything passing me

hi if its a 2000 car its the ford gearbox so would benefit from a oil change, which is cheap as it uses standard atf oil change can cure most faults and atf is cheap so a good place to start cheers Joe

Hi Mark, So can i ask were you driving when the warning came on or had you just started the car? had it been used regularly or left standing? and when you restarted it disappeared is that correct? Some times restarting the car will clear the warning. If that was the case probably just caused by electrical problem as happened on my XF. Had no further problems. Kind regards, Julie. I have this article if this helps at all WHAT DOES “RESTRICTED PERFORMANCE” MEAN? Primarily seen on S-type and XJ-Series Jaguars, when the restricted performance error message lights up, it means the engine management system has determined a problem. Often this happens either at a cold start or while accelerating, and when it happens, the engine management system then throttles the engine, cutting back on performance in order to protect the vehicle. You’ll most likely cap out at 1800-2000 RPM when trying to accelerate. COMMON CAUSES OF RESTRICTED PERFORMANCE So, now that you know your car is sensing a problem, you need to get to the bottom of what’s causing the restricted performance signal on your Jaguar. The best way to really know for sure is to take it to a mechanic who specializes in imports, namely Jaguars, and have them hook it up to a diagnostic scanner. Once they know the exact source of the problem, they can get to the bottom of fixing it so you can be back at max performance sooner rather than later. There are a few likely causes to why this error message came on, including: - An issue with the catalytic converter that turns controls exhaust emission and minimizes toxic fumes; - Fuel system problem, including a clog in the fuel line or an issue with the pump. - Air intake issues, such as leaks in the air flow, mass airflow problems, intercooler hoses, or throttle body housing; Some of these are very simple fixes, such as the breather hose disconnecting from the throttle body, or a leaking hose that needs to be replaced. In some cases, such as a problem with the turbo turbine inlet valve, you’re looking at a more complicated repair. DIAGNOSING YOUR JAGUAR Before you take it in to a mechanic, there are some DIY solutions that may fix the issue.Take care to check: - Air intake box or air filter housing, and check for cracks and make sure the clasps are fastened properly. - Breather hose from the engine that crosses the intake pipe to be sure it’s secure and attached; - Mass airflow sensor after the air intake box. Carefully clean it and verify the wiring harness is fastened; - O-ring seals around the oil dipstick and breather hoses between the engine and firewall; If the car doesn’t start at all, the problem may be an issue with the fuel line or pump. CLEARING THE RESTRICTED PERFORMANCE ERROR MESSAGE In some cases, the simple “turning it off and on again” method may do the trick. If you can, pull the car into a parking lot or other safe location and turn it off. Give it two or three minutes, then switch on the ignition, but don’t turn the key all the way. Wait until the lights have gone off (except for the four that stay on all times). Then start the car. If this doesn’t take care of the problem, it’s important to drive the car as little as possible until you can get to the root of the problem and take care of it.

Hi Benjamin, Welcome to the club. Its a difficult choice, I am sure some if the members will be able to help with ideas. I have owned s type, x type and XF. I personally love the look of older cars. Best Wishes, Julie.

HI The gearboxes are rebuild able and repairable first step would be get codes read with Jaguar ids/sdd software to see what fault is and go from there could be a sticky solenoid in the gearbox to something as simple as a abs sensor, or even a air leak on the engine cheers Joe
