Sounds like overfill oil pressure too high. Oil level is critical. Engine can be damaged.
See my Solution for oil change.

Look in the glove box on the passenger side. Feel to the left top side of the opening and you should feel the valet button/ switch. To verify you tripped it, push cat head on the boot. If it does not open you found the switch and engaged it. You should only be able to open boot with the key from now on.

Hello. It seems either a headlamp relay is at fault and/or your headlamp switch is set to 'manual'. Good luck and keep me informed; if you want to.

Check the igniter module.
I assume you have a ecu code telling you #3 coil is missfiring ?
If so also check the crankshaft angle sensor .
If it is not an error code do a compression test and check the injector.
Hope this helps

on this website you find fuse box diagram and description for Jaguar S-Type (2001) https://www.carknowledge.info/jaguar-s-type-1999-2008-fuse-box-diagram/ https://www.autogenius.info/jaguar-s-type-1999-2008-fuse-box-diagram/

the problem you have is caused by the pats anti theft system is not recognising your key it may be the transponder or you may need a new key and get it programmed by a jag dealer or someone with the needed gear to do it with best advise take it to a jag dealer

My guess would be bad socket.

First change the belt driving the compressor. Belt slippage is the number one cause of low cooing at idle or slow speeds (if the charge is OK)

Your car has a module for the FOB , that could need to be replaced and programmed , or just to reprogram keys again

the fuel pump has got a 12volt constant supply the ground is pulse width modulated to control fuel pressure as its a single line supply thats why the readings you are getting

that sounds like the door latch assembly is faulty it does not use the same micro switch for door open signal has the interior light

Is it still not starting if not then you might have triggered theft detterant system which can be turned off with reprogramming of ignition module. Did you recently have any work done to ignition ignition switch or key switch there is usually a way you can bypass it

may be a camshaft chain problem your aj26 or aj27 engine is prone to broken chain tensioner/guide problems they are plastic you need to go to a speciaist jag/engine person . good luck

Hello Check the wiring in the place you have used the hammer , as there are wiring harness going through the fender

Hello Check the Air Mass

the throttle body angle is the throttle butterfly opening angle, the signal is sent to the ecm from a potentiometer on the throttle body and is compared to the throttle pedal sensor if both signals are not in unison then you get that fault code you dont say what model you have! if its got a cable operated throttle pedal the pedal sensor is also on the throttle body. so you should clean the butterfly and housing using a solvent and check the wiring and connectors but at that year 99 to 2001 they had problems with throttle bodies lots had to be replaced. so recon throttle body may be best option
