My name is Robt100, and I have an addiction to Autoshite purchases....

Right then, a small update.....
After the rear light debacle, Ron was just getting the MOT sorted. Went out yesterday to drive it out of the yard and... its turned itself into a low-rider

Tried running the car - No pump running

Turned out with a bit of investigation to be a dodgy plug on the pump solenoid valve. So pump back to working again, good news? No, sadly not....

Even with the pump running the car would not rise up. Did the usual 2 min run then stopped. So onto the system in the boot.....

Taking the feed pipe off let a little bit of pressure escape, so something was happening. Ron connected up a pressure gauge to the line-in and it was struggling to even get the gauge to show anything. Suggesting the pump. He then plugged his workshop compressor into the valve body, and 6 bar raised the car 1 inch, so seems the valve body/struts are still operational.

But it makes me wonder what has happened, as a failed pump shouldn't cause the car to drop surely? As that should be stopped by the valve in the distribution block/manifold isn't it??? Which makes me wonder if there is something else playing up. Worryingly, amongst the bag of bits that came with the car, I have found one of BagpipingAndy's rebuild kits! So will be dropping that off later next week to see if that helps build the pressure.

But my main concern is why it dropped, could there be something else wrong, or just some weird quirk of a failed pump?
I vaguely remember the OSR going down by maybe 1inch after sitting for 4 weeks, could all the fiddling round with the fusebox etc in that area have disturbed something?

Bit of an update on the above. @Jikovron has been earning his keep troubleshooting things. Put a pump rebuild kit on it and cleaned up the drier side (it was a mess) then refitted the pump and.............. 

Sod all inflating.

Vid after turning off, so definitely a leak somewhere between the pump and distro block

New pump time? Or a hidden feed pipe from the pump to the tank that may have a leak, no idea where it runs to/from?

[robt100]

Right, another small update.
Changed the pump out, main dealer jag want £1,345 for theirs....so got a chinese special (probably from the same factory as jag!) for £92 instead 😅

All fitted and....

IT WORKS!!!


Now just to hide the slightly worse for wear brake hardlines under a slab of grease to protect them and its MOT time.....unless it decides to throw another wobbly!

Long live the XJR!

Managed to get over to @Jikovron today to pick it up. In typical JLR fashion it has a few electrical niggles, "restricted performance" has popped up again pointing at a knock sensor, and the OS headlight likes to flicker every now and again, but got a feeling some of that is probably down to sitting for 2 years!
So apart from not being able to go past 3k (not that its a problem for normal driving) its lovely, very comfy and quiet, and even got 26mpg on the way home, for a 4.2V8 with a supercharger I dont think thats too bad!

[robt100]

Well, this weekend was dedicated to getting the Jag sorted if I could. Started by giving it a clean on Friday before the sun faded away, looked much better!

Next job, try and find this P0333 error and fix it. P0333 knock sensor - high voltage, after a bit of digging around it seems that this can come up also due to a connection fault as well as a failed Knock sensor. Not one to reject the option of getting something fixed for pennies rather than pounds I had a bit of a dig around the wiring loom to check on the connection......




Yep, that'd do it!! Brown wire completely detached and the black wire chafed and not far behind! After a little bit of youtubing to see how to get the pins out of the plug. Grabbed some wire from an old sierra EFi loom I had on the Capri 10 years ago (and mentioned it to the wife to prove that keeping tat for decades IS a good thing🤣) and got out the soldering iron. All wired up and the error has gone!

Took it out for a little drive, booted it and, oh dear, lurching with my foot down...

Hold on...

Ahh all ok, just the TC clinging on for dear life to 400+ BHP on a wet road😁

With a slightly more graceful right foot, it shifts, like, REALLY shifts. If I have a licence left by the end of 2026 I think I'll be lucky🙈

This is truly great news. Youve shown great persistence with this, something i definitely wouldnt of had with it.

But yes, they really are ballistic. Theyre not heavy and they are big power. The supercharger whine, the back of the seat g force pin. All in sublime comfort. Well done that man

Not sure its "my" persistence. More that of @Jikovron who has spent about a year working on it😬 so a big thanks to him really!

Next job....fit the detachable towball and really confuse the locals 🤣

I noticed the towing capacity for an X308 when I was reading the brochure the other day is 1900KG. I bet it would look impressive towing a twin axle caravan but I shudder to think of how bad the fuel economy would be.

[robt100]

I would think you'd be lucky to see double digits @Heidel_Kakao🙈

Tiny update for today, bonnet wasn't closing easily, so adjusted the brackets/hooks on the bonnet, passenger side shuts fine, drivers side...nope, nothing. Tried activating the latch with a trusty screwdriver and yeah, drivers side just pings back to open, no latching mechanism on it for some reason. So £20 to Autoreserve Jag for a spare one, hopefully I can get that done and save the bonnet flapping about!

[robt100]

Well, so much for it all being sorted....
Restricted performance popped back and dissappeared again the other day, EML on but no codes on a basic reader.

Oh, and got a new latch for the bonnet as advised, and nope, not that. The cable is knackered, seized up so it wouldnt return to lock the latch after opening. Middle section has rusted out of the sheath and is all bent, have done an AS special and filled it with half a bottle of 3in1 for the time being, but looks like its going to be a new cable job, why Jag couldnt have made the cable between the two latches a seperate piece is baffling, instead you need to redo the whole thing.
Oh and the wiper mech is now screaching, so got to get the scuttle panels apart to lube everything up 🙄

[robt100]

I've put the bonnet cable issue to one side for the moment (probably to my detrement later on no doubt!) to try and focus on getting the restricted performance warning to stop coming up intermittently. Both the code reader and SDD seem to not be able to find any fault codes But as the car is an early XJR, and has been through around 4 different drivers over the last 800 miles over the span of 3 years, I decided its probably best to reset the TCM adaptations and if possible, update the firmware. So Thursday in the pouring rain was coding day (thank goodness for the carport to keep me dry!)

 

Thankfully there is an outside socket right next to the car, so could hook up a battery charger and keep the laptop on mains supply too. Got a chance to go out for a gentle test drive today to try and do the calibration run (a little hard to find a quiet flat road when you live in a dip between 2 schools 500m from the A1) as best as I could. All seems to be ok, its definitely different, the clutch flare seems to be from 1-2-3 now, but I think its just finding its feet, at least there is no harsh changes. Will give it a bit more running and see how it behaves.

I did struggle to find out how to just do a normal code scan in SDD,if anyone can point to a step by step that'd be helpful. It really is a clunky bit of software! Oddly the flight recorder part that stores codes had no mileage or date for anything it had logged, so trying to track anything down was....interesting. On the plus side, it did (Sadly) confirm that the head unit hasn't been swapped and there is no modules for heated seats or a heated screen...even though it has one fitted.

 

[robt100]

Was buying up parts for sevicing the BMW last night, and decided to get some for the Jag too, as going through the service book and recipts I couldn't see anything for an oil change since 2018, over 50k miles ago😬......
Then today I thought I'd message @DirtyDaily just to check if he knew as he bought it from the fella, but first I checked the original for sale thread and what do I find....it had a service and new sump gaskets etc just before buying it.....800 miles ago! @DirtyDaily you never updated the service book ya git 🤣 ahh well, given its spent 2 years sitting and spent most of that running crazy rich and idling due to all the new appearing faults and fixing, its probably worth changing anyway! Also got a replacement PCV valve as its looking pretty caked up. Hoping it'll be a nice simple job. 

And yes, I know the best way to spend my time off in December😅

On another note, the wiper mechanism is having a good screech as it wipes. When the BMW did that the arm and mech came off at 70mph on the motorway, hoping this one doesn't do the same because it looks a horrible job!
