the most likely cause is the dual control valve in the cooling system and/or the wiring to it. you can change the settings back to the origional settings using the touch screen or the dash switches . @ your model/year there was a factory fix which was about changing the servo motors on the climate control unit for that problem.you may need to take to a jag dealer. but first make sure the outside temp is reading ok on the dispay that can also cause that prob if its gone faulty

sounds like you have a auto gearbox fluid leak and is running low on fluid needs topping up and the leak fixed try and locate the leak area if its under the box and its a mercedes unit the wiring connector seals are favorite if its a zf box the prob with fluid leaks are not norm a problem unless the oil cooler has been damaged by a stone chip its behind the front bumper liner but which either way the fluid is more than likely low if you keep driving it you may damage the gearbox

put on high beam and check where the power is not getting to it could be high beam relay/s or light switch problem

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

if u havent had it serviced for a while then its likely that a filter is cloged, time for a service.

I had a very similar issue, it wound up being a wire that had burned almost in 1/2. It was shorting out. You will need to get a diagram of your vehicles wiring and check the wires, most of the time it is somewhere close to the exhaust. .

your car have a soon roof ? check if safe close

the stype does not have ignition amplifirers the on plug coils are controlled by the power controle module [pcm] loated under the climate intake box and is prone to water ingress.but there are a coil suppressor capacitor on the back of the cylinder heads which can go short to ground. what is the problem you have?

Sounds like traction lock in the differential is engaged. Try having the oil changed with the friction modifier additive. A bad speed sensor will affect locking and unlocking function. damage to friction plates will occur if not corrected.

Sounds like the rag joint in the steering shaft has come apart. A loss of control hazard exist, do not drive until you check steering shaft joint connections at firewall and rack and pinion unit as well as tie rod ends.

you have got a faulty spark plug or a on plug coil change the plugs or get the fault codes out of odb11 system that will tell you which coil has failed you will need a code reader to help or someone who has access to one

its 2 differant systems they dont match

Chilton or haines manuals are very helpful.Also, local parts stores will show you how if you ask them.You need the filler hose any ways.and some refrigerant.

You have plastic gears in the roof mech that tend to chip and break over time. Take plenty of photos as you go and take your time. Im sure you will be able to find a solution .

In order to help you I would need the contro system read for fault codes and go from there.

it is to be investigated by experienced mechanic: a way too many causes such things

Rule of thumb with ignition bits is, change one you change them all. This means Plugs and Leads mostly. Saves headaches like the one you have now. If 1 fails you can bet the rest are not far behind it.

Have your CDI unit checked, sounds electrical or your PLUG wires, now days the plug leads are cabon filled and they break down causing this type of problem not expensive to replace
