66k miles Just bought this pretty cat and I am not sure what is the best thing to do first. I was thinking change all the fluids and filters. What are the best fluids to use?

 

Check the (4) lines to/from the front mounted oil cooler. The rubber/Aluminum interfaces are known to separate unexpectedly and deprive the engine of its most needed oil in a matter of seconds. There is usually some seepage around these crimped sections when they are about to fail. FWIW, the general understanding is that these hydraulic lines are good for 10 years. Easy job but somewhat pricey parts ($400?).

Next is to check the (2) rubber heater hoses that go from the thermostat area to the back of the engine in the valley between the heads, aka valley hoses. They are somewhat hard to get to and therefore get neglected. Check them for firmness if they feel original.

Also, read up on the green shower if you have a convertible. The later parts have a reputation to be of lesser quality than earlier models.

Last, you cannot go wrong starting with a cheap ELM327 scan tool and a mobile app to read/clear OBDII codes and runtime data.

Best of luck, keep us posted.

 

Is a cheap scanner OK There are many choices, what is the better choice.

 

Those ELM327 are so cheap, you just have to have one. They are generic OBDII, but still very useful.

Then, over time, you will likely need a Jaguar/Land-Rover handheld reader. Foxwell and iCarSoft are often mentioned.

 

First things to do all good suggests. On my 2000, I had zero luck trying to read codes w/ an Innova 3100. Works fine on my other cars. It's a brand/model approved by several other forum members. Powered up ok, display said "reading" and then nothing. Tried to read w/ a second good quality reader. Nothing. However my mechanic had no problem when using Jag diagnostics. Didn't mentioned repairing anything, broken wires, replacing fuses, etc. When I checked, there were many forum reports of not being able to read codes. Why can some owners pull codes w/ no problems?

 

The car has multiple active data networks (CAN, SCP, and ISO-9141). OBDII data is only available over ISO-9141. Maybe your scanner detects CAN (the better, faster protocol) and locks on it, and fails to obtain OBDII information. Check if you can "force" your scanner to read over ISO-9141.

 

Thanks for the feedback. I don't know how to "force" my scanner ( a basic Innova 3100). I have on/off, connect, read and erase options. iCarSoft a good idea? I plan to buy something more expensive to get Jag specific codes, real time data, etc.
