Jaguar Owners Club

Hi Fraser I know this S-Type as I have worked on it and it's generally a very tidy car all round. The owner has rectified a few of the known issues and fitted many parts recently (Thermostat Housing, Brake Servo, Service, etc) https://www.gumtree.com/p/jaguar/jaguar-s-type-2.7-diesel-sport-2005-manual-gearbox-75k-miles/1349410603 It's based in Dorset and I think he'll shift a little on the price

I would say that you possibly have a bad earth or a short circuit to ground Either one or more of the injectors are defective (one I could understand, even maybe two but anymore than that there has to be a common fault)...or... there is a short to earth on the loom feeding the injectors. If this is the case then you would have the injectors running constantly. If they are not running constantly then it must be a relay or ECU fault which is feeding power through the earth feed (probably a poor connection or corrosion). Easiest place to start is the System/Main Relay

Can you please let us know if this has this resolved the issue(s), thanks

Hi Andrew....welcome to the Forum That is correct for the injectors to have a 12v permanent feed as the they are triggered by an earth feed from the ECU (more stable way of firing an injector). I would check the system and fuel pump relays first Good to have you onboard Cheers, Trevor

Hi Neil.....welcome to the Forum Fine looking Jag Good to have you onboard Cheers, Trevor

Maybe worth having the level checked and if it needs a slight top up then this may be sufficient to extinguish the warning light.

Hi....welcome to the Forums. Good luck with your next Jag purchase Cheers, Trevor

Hi Max....welcome to the Forum From my (poor) memory I seem to recall a post with similar symptoms in the dim and distance past....maybe worth searching the site with a few combinations of words, phrases to see what you come up with. Good to have you onboard Cheers . Trevor

Hi Gordon You can get one from Auto Reserve Jaguar (.com) and see if they have one for the XF in stock as this is an improvement and later version than the S Type servo. Should cost in the region of £160 (used one) part number: XR856588 (supercedes: part number: XR852441) Fitted one the other day and vastly improved the braking effort, and no noises and losing pressure either. The original had corrosion build up internally and this was leading to air leaking out through the pedal side of the servo.

Hi Jim good luck for the future and you know where we are if you return to a Jaguar Cheers, Trevor

Hi Patrick....welcome to the Club Which part of Germany did you tour ?

Hi Dave.....welcome to the Club

Hi Keith....welcome to the Forums

All I could find is the location and component diagram but it should be relatively accessible

Hi John....Welcome to the Club

It looks like the old Traffic Master system used on SatNavs of the past....would give live traffic data if subscribed to the system

Hi Tom. The best method is to back-flush the cooling system, so insert a hosepipe into a coolant hose in the reverse direction of the normal coolant flow, turn the heater on hot and disconnect the other main hose. In theory any deposits that could be blocking the system are dislodged and come out in the reverse flush. You shouldn't run the engine for this task. You can use an additive to clean it out at the same time but I have never used anything. Be careful to capture any antifreeze to reuse and not allow it to enter the drainage system, etc. Reconnect the hoses and fill with coolant, run the engine and test for leaks. It may also be worth replacing the coolant pressure cap as well as this can lead to coolant loss (loss of system pressure)

Here's my opinion on the issue! (sorry if I come across as bumptious but I have very strong feelings about this subject). First and foremost, the people, bodies, associations, etc that are debating the move to electric and demonising diesel engines are not automotive experts and very rarely are the motoring societies truly represented in meetings to discuss the future of motoring. Secondly, automotive technology is probably at the peak of innovation and cannot go much further with technological advances in the internal combustion engine....this also applies to trucks, diggers, ferries, generators...in fact anything with an ICE. The way forward is not via the electric route, albeit the Hybrid combination is by far the best option. Full plug-in electric cars will not save the planet and in fact, will have a huge impact on the planet and our daily lives (see recent press articles about EVs having to produce noise to avoid running over pedestrians that may step out unknowingly). Looking back in motoring history, steam cars and electric cars were used back in the 1910's in France (examples are in the Le Mans museum) and also 'Wet Scrubbers' were used on diesel engines which totally captured all particulates.....why have we gone to huge extremes to reinvent the wheel? Glad thats off my chest now but unless we have the infrastructure in place to successfully provide the power to run electric cars at no cost to the environment then it is not a viable way forward. Don't even get me started on autonomous cars 😞

Hi Paul . Perhaps the cabin filter is partially blocked ?

The deadline has approached and unfortunately, there are not enough members cars to make up the required 10 cars needed for club registration 😞 However, if you book in advance I believe entry is still the same price as the club stand price Enjoy the day!

I wonder if it is low on fluid or just needs changing? Would definitely take it to a transmission specialist to check it over

Hi Kevin Glad you are sorted and happy with the S-Type...minor glitches and then once sorted it should be plain sailing....Enjoy 🙂 Cheers, Trevor

Have not heard any problems resulting from anyone who has used them, except for the fact that it is plagiarised from the manufacturers 😞

Sorry Paul...not familiar with the system Wonder if JOE-DOT-COM can help out?

Hi Keith You could try a reset but otherwise it sounds like it could be a vacuum hose (or similar) could be dislodged or split as it would take a reading from the engine load to carry out calculations.
