    The brakes lights stopped working ever since the message of park brake fault, the garage guy said that the battery is giving off too much power but the car is working fine. I will take it to an independence garage. I am just annoyed that i spent 1300 and it has created me another issue to fix. It would be much simpler if i knew someone trustworthy as i had bad experiences with garages.

    If the brake lights are not working at the moment then this is a big indicator that the brake light switch is faulty.
    I'd tackle this job yourself if you don't trust anyone. I believe it's simple and you'll find good help here too.
    The brake pedal switch is a cheap part.
    Also, make sure that new battery is fully charged first, if you haven't been using the car and the battery came from dealer stock, then it's worth giving it a good charge. If you don't have a charger then a good 35 mile run should be ok. But I wouldn't without brake lights.
    If you have a multimeter then put it across the battery terminals and see what it says with the car off and with it running. Post back results.

    Will the break pedal switch solve all the messages? I do not have a multimeter but i will take it for a run but what will this do? Yes diy its much cheaper. Another thing is i been getting water in fuel message for a year and have figured i need a water fuel sensor. Anyone know how much will it be to install it or can i install myself? And if i install a new parking brake module will it eliminate the other signs (gearbox fault and dsg not available)

    As far as I'm aware, the brake pedal switch can cause all the brake related errors you describe if it is faulty. Can someone confirm this please?
    A poorly charged battery can also cause the issues you describe, even though it is good enough to start the car. Driving it will charge the battery, actually in your case just letting it idle on the drive would be better. You'd need to leave it for, I guess, half an hour or so, to be sure that it is decently charged.
    To keep things simple, I would start a new thread for advice on the water fuel sensor as this is a separate issue.

    The OP said battery and alternator were new so unless faulty should be OK. The reason I asked about brake lights was that this would point to the brake pedal switch not functioning which could also be causing the other errors. Pity the Jag dealer didn't spot this when they had the car. Seems a cheap option and can be a DIY job. You probably don't need the parking brake module and is worth changing the switch first as these are known to be faulty.

    Water in fuel could be the sensor or could be water in the fuel. I had this message a couple of times and just swapped the filter as this is a serviceable item and easy to change. If it isn't this it could be the sensor which is screwed under the filter - you will remove it when/if you change the filter. You could change both at the same time but the sensor is very expensive and so easy to change later if the filter doesn't fix it.

    To be fair to the garage, you did say the handbrake issue was there before they changed the battery and alternator, so I think they fixed some of the issues but not all. They should have looked into these a bit more or at least advised the handbrake was faulty.

    I found a switch for £10 does that sound right and can you explain how to do it and also i found a water sensor for £60 does that also sound good or not. Would you suggest to do this before i take it to a independence garage or tell them to replace it or can a local dealer do it.

    The water in fuel message may mean there is water in your fuel - this is what the sensor is there to detect and doesn't mean it needs to be replaced. But, it could be a faulty sensor causing this, but my approach was to replace the filter first as this will need changing at some point anyway. If the message continues it could be the sensor. Your call on which you replace first.

    Brake light switch: Personally, I would buy a new switch, I think they are around £30 to be confident that if the issue persists it isn't a faulty switch you have just fitted. If you get a garage to do this it may be an advantage to let them source the parts as they will offer a guarantee.
    How confident are you with doing this yourself? I think it can be done but is a bit awkward to get to, so may be worth getting a garage to help. I haven't done this but others may be able to offer advice on what exactly is involved.

    There are no guarantees this will fix the issue, but the combination of problems you have points to towards this as a fix and could save a lot of money if it works. Good luck sorting this, please keep us posted nohow you are getting on.

    I'm not sure of the issue but clearly neither is the dealer. You've fallen into a very common trap.

    You have an odd problem - off the main dealer as they're the experts - right?
    WRONG! Very Wrong.
    The guy working on your car has probably been at that dealership less than 5 years. That means he's not that up on X250s at all and has probably done nothing more than a couple of oil changes on pre facelift ones in his entire career. Your car is simply too old. Dealers rarely see them. Sure he can give you chapter and verse on issues that affect the brand new ones, but issues that only appear after 8-10 years? Nah. He's less qualified to work on your car than your local backstreet garage.
    What he does have is the full Jaguar diagnostic system, what he lacks is the skills or experience to interpret them. And you're paying him twice what you'd pay anyone else. Worse, he will simply charge you stock dealer new prices (£1200 for a battery and alternator - you're having a laugh - or at least he is). He'll never attempt to get anything repaired, never look at used parts and never perfectly good OEM parts for half the price.

    Your local mechanic is probably vastly more experienced but being a generalist doesn't have the diagnostic kit specific to Jaguar. Fine for most issues but tricky diagnostics can be a challenge.
    What to do?
    Find a Jaguar specialist. They spend their days working on car like yours. Could well have seen this before but even if not, will almost certainly have spent time chasing down similar issues. Will have used parts on the shelf he can swap in to test and will charge you a fraction of the labour charges.

    My car is 2 years younger than yours. It hasn't been near a dealer for several years and to be truthful, never will again.

    Story:
    Back 2005, I sat in the Mercedes dealer waiting to collect my nearly new E class from it's first service. At the next desk sat an elderly gentleman. They were telling him the head would need to come off for more diagnostics and were throwing prices around I found terrifying. I looked through the workshop window and saw his car. A clearly cherished late 80's S class. All I could think was that they lad who was working on that car is unlikely ever to have seen that engine before. Odds are, he was in nappies when it was built. In contrast, the local specialist had a car park full of them and identical cars, with no doubt identical issues, lined up in front of the workshop waiting to be fixed by someone who does this for a living, knows all the tricks and shortcuts and charges less than half the hourly rate.
    He'd taken it to the most expensive, least experienced place possible.
    I once took my car to them with a nasty whistle coming from the heater fan. Dealer had already discussed dismantling the fan unit and quoted between £400-£1000 to investigate and fix.
    Guy came out, listened for 2 seconds and said, 'your fan is fine, believe it or not its the regulator, easy to swap but I'll warn you they're pricey". He even told me how to access it. A week later I handed £200 to the dealer parts guy and had them swapped over inside 15 minutes.
    Ignore the fancy waiting area and logos, you need an expert and you won't find one where you're going.

How trustworthy is an independent dealer and how much do they charge for an assessment (is it a diagnostic procedure).
    Apologies for the delayed reply. If it was me I would contact Chris Isle at the Jag Specialist, Armthorpe (Doncaster) He may advise you over the phone Even if he’s not yet open. He has a very good reputation.

    I had an X356 (XJ6) that had similar messages. My rear brake disc's needed changing as there was a large ridge around the outside of the disc. Once I replaced the discs and pads all messages reset and never came back.
    What condition are your rear disc's in?
    I'm no mechanic BTW, just a keen DIYer
    Sadly Jag-less at the moment, but started looking for an XE
