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.

Keep us informed of how it all goes....hopefully in your favour as well

Hi Alan....welcome to the Forum

It could possibly be the Air Con fans not working (e.g. seized) and the system kicking out because of it.

Alternatively, it could be the a/c system relay.
Had that happen on my Honda CR-V with the a/c relay which then tripped out and also put on the Engine Management lamp.
Managed to get a new replacement relay from eBay for about £3 and reset the system which cured it.

Let us know what you find 

Hi Phil

Sorry to hear of your unfortunate dilemma with the dealership and the tainted XF.
It tends to leave you with a bad taste that can take forever to lose, if at all.

I would definitely return the car to them for a full refund as if they have to remove the dashboard to replace the leaking heater matrix then this can sometimes change the whole feeling of the car by introducing new squeaks and rattles of which constantly remind you of the initial problems.

Sorry to add fuel to the fire but it does anger me to hear of some (not all) dealers deliberately palming off problem vehicles to the unsuspecting public.
Keep up updated on the outcome

sounds like the sensors need reprogramming to read the current pressures.
you would need specialist equipment to carry out this procedure, but shouldn't cost much at a reputable Jaguar specialist repairer.

Sounds like a glitch in the SDD programming...would mention it to the supplier and see if there is an update available
