You need to do a good vacuum ( about 500 micron) problably this car work with R12 refrigerant. This gaz is not legal now you have to find a remplacement. With the new gaz , a chart tell you how percent gaz of the new one you have to insert in system. If it's work with R134 , you have to put exactly the amont of gaz write on the plate on the hood. You need lot of speciality tool, may be it much better ask to somebody know her job. Mario

Actually i does not have the solution for your problem but i wanna say about leaks caused by AC water. Do you guys know how to repair them? Liquid Roof Coatings Application and Uses BuyLiquidRoof

when you pressure was a car meaning engine or under you have to wait till is fully dry you may have short circuit your ecm or ignition depending where is located or is the alternator due to the water .

Apparently you have a leak, but failed to disclose where. An internal leak would come out of the exhaust pipe and would be white smoke.

What year model?? Here is a link to JaguarForums.com--- LINK: http://www.jaguarforums.com/forum/new-member-area-intro-must-5/

idk

use the vin number and go to a jaguar dealer it will cost you about 65.00 I had the same problem. The vin number is on your title and your registration

I just purchased a FSM (Field Service Manual/downloaded online from eBay) and this is all I can find out about the timing on an S-Type. If you would like a copy of the manual, I would be more than happy to send it to you as an attachment if allowed. Email me.. [email protected]. My name is Jan, retired, and tired of the problems my 2001 Jag S-Type 4.0 is giving me, but still love it.Variable Valve Timing (VVT)The variable valve timing system improves both low speed and high speed engine performance, engine idle quality andexhaust emissions. It is an infinitely variable system operating on the intake camshafts only. There is the equivalent of 48? ofcrankshaft movement between the retarded and advanced positions. Engine oil pressure operates the system under thecontrol of the ECM.For each intake camshaft there is a valve timing unit, a bush carrier assembly and a VVT solenoid.The valve timing unit turns the intake camshaft in relation to the primary chain to advance and retard the timing.The unit consists of a body and sprocket assembly separated from an inner sleeve by a ring piston and two ring gears; theinner sleeve is bolted to the camshaft.The ring gears engage in opposing helical splines on both the body and sprocket assembly and the inner sleeve, to transmitdrive from the assembly to the inner sleeve.Engine oil pressure moves the ring gears and piston to turn the inner sleeve in the advanced timing direction and a returnspring reverses the direction for retard.Additional springs absorb rotational and axial backlash to reduce noise and wear.Variable Valve Timing (VVT) SolenoidThe valve timing solenoid controls the position of the shuttlevalve in the bush carrier. A plunger on the solenoid extends when the solenoid is energized and retracts when the solenoid is de-energized.With the vehicle stationary and the engine compartment open, operation of the valve timing solenoids may be audible when the lubrication pulse occurs at engine idle speed.

A fuse is designed to fail if a short or high amp draw condition occurs, a fuse can not cause a secondary safety(breaker) to trip.The unit has developed a short and must be replaced.

Check for a clogged condensate drain line (a/c heat exchanger) which would cause it to overflow onto the floor. It could also be a windshield or sunroof leak. I've had this very same problem from the top of the windshield leaking. There was a very small gap between the windshield and the edge of the roof, Where it's mounted. I had to use a pressurized garden hose to find the leak.

run a fault code check as it appears that the cpu has gone into limp home mode (restricted performance). The cpu runs checks of all sensors and when one gores out of parameters it restricts the engine to protect the unit and accessories.

starter solenoid or starter itself bad or starter relay under hood could be bad
