fuel pump relay?

doesnt have one ,on the XJ40 model its a computer type thingy located behind the radio right hand side ,and the relays burn out ,i have managed to solder some old ones in out of a relay but ? this a newer model which i havent repaired as YET ,,, but it could be in same place ? just be carefull of the ski jump when removing it ,two screws under ashtray on mine

Not being a smart Alec but the same place every car has them. Yours should have a plastic engine cover that you have to remove first. The plugs will then be visible in the standard locations on the cylinder heads.

a common problem on these cars is a wire breaking off the combination indicator/dip switch. remove the steering column cowlings and check that first, it can be repaired by resoldering if thats ok check the dip beam relay and wiring etc.hope that helps.

It's possible one of your ignition coils went out if you have a check engine light have it scanned it will pinpoint that issue.

call the dealer and have them get it towed that way if something happens they are responsible.

Wow, by that many miles you may be looking at new coil packs. You can replace one that you know misfires and see if that helps. They are usually not cheap - try rockauto RockAuto Parts Catalog RockAuto Parts Catalog RockAuto Parts Catalog

A/C sounds like an issue with the a/c module which is unusual. There used to be a test sequence on the earlier a/c units not sure if it is on the 4.2. Check all fuses there are four fuse boxes. one at the end of the dash by the door and two under the bonnet. the radio/cd player etc is all one unit (medIa unit), that would explain why they all are not working. I think the a/c fault is connected to the media unit but not sure how. Need to study the wiring diagram for this, I take that it is a 4.2. Jaguar diagnostics will show the fault or give a lot more guidance. Generic scanners wont pick up the fault codes for things like this they are manufacturer specific. That's how manufacturers lighten your wallet. website jagrepair has all the electrical diagrams free.

Hi Antonio , What is the real problem ? are you getting RPM needle fluctuation while driving or the the engine light that came up after that minor engine service ? As I understand you are having fluctuating RPM after that minor engine tune up. If there is no sound than it could be a problem of throttle body.

all back seats are either screwed down or hooked in. you need to use a little muscle and lift up your back seat to see which is which. there is no other way to gain entry to your trunk.Trust me Ive locked my keys in my trunk too. Now i have a hidden spare to my door and trunk. GOOD LUCK

if the park brake warning is on and the park brake is inop. there are several common problems with this system, the most likely causes are 1 the rear brake caliper sliders are part siezed or the pads siezed in the caliper frame 2 the wiring to the park brake motor open circuit or rubbed through on the rear subframe.3 the park brake motor has failed, you really needto get the fault codes out of the park brake module if the above checks out ok the above faults i have found to be the cause 9 out of 10 times. hope this helps.

You can use the key on the trunk the key aperture is at the right side of the trunk. Hopefully it is not seized from lack of use. As you turn the key try thumping the boot above the top of the back edge with your hand not too hard and also rocking the car by the boot

unusual for only one corner to be out, the common problems are, air leaks, between valve block and suspension unit, ride level sensors, normally the clamp on the suspension corrodes and allows the sensor to float,it sounds like a air leak on that corner to me. you can buy a leak detection spray to help find the leak. the pump is also troublesome. located front bumper liner lh, but that would affect the whole system, I would check the plastic pipe is ok from the valve block to the suspension unit first, then get the fault codes out of the air suspension module, the valve block is in the boot spare wheel well. hope this helps.

Check the u-joints in the drive shaft for looseness or rust streaks. The speed makes it well above harmonic vibrations normally occur. Check rear engine mount for condition and if the rubber is soft it may pay to replace it. The jaguar car rear end uses the two axles as upper control arms and so it may be necessary to check the u- joints here as they carry a lot of load holding the wheels upright while driving the car. It may pay to find a jaguar. specialist workshop because the drive train and rear end are not the same as most other cars and general mechanics will have little specific knowledge to diagnose the problem correctly

Folding mirrors normally have a setting to fold automatically or to fold only manually. https://www.google.com/search?q=jaguar+xe+folding+mirrors The passenger door not locking is likely a broken wire or a door module issue. For that, you need an auto electrician who has access to data sheets and also has a pro grade scan tool computer. The scan tool is bi-directional and can instruct things to happen electronically and verify that they did and if they didn't why? https://www.google.com/search?q=auto+electrician+near+me ..
