Jaguar XJ8 - 4 months in, STILL BROKEN?

Показать описание

Time for an update on the 2002 Jaguar XJ8 Sport (X308 type), and what better place to do it than at a mid-week testing session at the Oulton Park racing circuit?
In this video I talk about work done to date, including jobs undertaken since the last Jaguar update, and whether any of this has helped eradicate the regular error codes and breakdowns that I'd been experiencing.
If you're new to the Old Classic Car channel, this old 3.2 litre V8 XJ8 had seen sat outside a garage looking more than a little forlorn for several years. I decided that it'd make a good candidate as a wafter, especially for longer trips to shows, museums etc. But this plan would only work out if I could persuade it to stop throwing up multiple error messages and dropping into "failsafe" mode, ie limp mode. A lot of time has been spent on Jaguar XJ8/X308 forums, reading about how other people have dealt with these commonly-encountered ailments.
As there were a number of interesting old cars at Oulton Park on the day of recording this, I grabbed a few clips and have included them here.
Comments, likes and subs welcomed as always, thanks!

Very brave of you to let the car hear you saying things are working.

One of your comments is particularly pertinent to the X300 range and that is use your car regularly. I speak from experience, XJR6, XJR8, and currently X308 Sov LWB 4L. Gets 2 local journeys a week and around 120 miles each weekend. Also, these cars demand constant maintenance.

I suspect that a lot of Jag owners don't keep on top of maintenance and issues as they develop. When the "tardy" performance, and Xmas Lights take over the dashboard, they sell them on...cheap!

Hello Richard, I recently sold my 2000 XKR, basically because it wasn't getting used. The problems you have encountered with your XJ8 are very similar to what I experienced with mine. If not used regularly and the battery slightly down on voltage it would light up like Blackpool illuminations.
I still have my XJ40, which still has lots of electronics but is not so temperamental. Were once rust was the bane of classic car owners, I now think aging electronics and deteriorating plastics are more of a worry.
And on that cheerful note, love your channel. Thanks for posting.

So pleased that the Jag is performing better. Well done.

I sincerely hope that all your efforts are not in vain. Such a good-looking car deserves to stay well north of Beachy Head. Thanks for the update and good luck!

I have a 2003 Jaguar XJ8 4.0 V8 (X308), registered in Japan Feb 2003 so one of the last made. The car has been back in UK 5 years, I have owned 2 years. I was having the ABS warning coming up and assumed it was the 2 dry solder joints you mentioned. The ABS module is extreme front left of engine bay. The plastic control box is bolted to an aluminium block manifold with lots of brake pipes coming out the top, bending across and down the other side of the plastic box. I disconnected the car battery. Undid the 4 long bolts connecting the plastic box to the aluminium block and disconnected the 2 electrical connectors. The box does not slide away because it slips over location spigots. The only way to pull the box away clear of these is to slide it out first before you can slide sideways, so you have to carefully pull and bend the brake pipes towards the engine, until you get clearance and a gap to pull it out clear of the spigots and then slide clear. Some people drill a hole with a holesaw above where the 2 joints are. I decided to run a hacksaw blade around the facory joint and split the casing. I was so happy to see two quite obvious dry joints where the 2 main wires come in. My mate heated up each joint to melting point and added a wee bit of solder for good luck. I used a black sealant to make the joint good on the control box and then replaced in the car. Re-connected and re-bolted. Re-connected the battery, started the car up more ABS warning light. I then pushed the brake pipes back as they were and you would never know I had been in there. Now I only have an issue with Restricted Performance and codes 0171 and 0174....lean fuel banks 1 & 2. Currently trying to get to the bottom of that. Ron, Glasgow.

Not surprised this has 461 likes so far - I just added the 461st one. I will say this guy needs a medal for his patience not losing his rag and resisting throwing the wretched car off a cliff! His perseverance paid off in the end.

Got a 308 4.0. Daily driver - not had your issues - but find posts like yours super useful as I like to intervene before I have a problem. Thanks

Thanks for the update, I was wondering if you’d sorted it, let’s hope you’ve nailed it. By the way, that very late Yellow RS2000 in the background was a thing of beauty !

Now that is very useful information to everyone with cars from the last 25 years . Persistence has paid off . I suspect cars have been put in to auctions in desperation . In the back of my mind the words 'hard reset' ring a bell.

Good to hear all is well again Rick.. car looks fab an awesome side profile with those alloys!! Fingers crossed for trouble free motoring going forward!

Well done for persevering. My 16year old Clio Sport had a 'wobble' earlier this year and took some time to get to the bottom of what kept making various dash lights appear. I like your 'Beachy Head' comment to describe how fed up it makes you feel. All sorted now but parts were a nightmare to source. Fingers crossed for both of us!

Great summary review. I did get the diagnostic tool and have been tracking down the mostly electronic bits on my 2004 XJR. I'm down to tracking down the heated seats front and back, front blower motor and a fidgety center console screen that works perfectly above 50 degrees and doesn't turn on below that until the car is running for about 20 minutes. I love watching your videos and learning from your adventures with your X308. I have absolutely found that the more the car is driven the better it gets and the bugs become fewer.

Glad to hear you had success so far. Hopefully it will behave from now on. It amazes me that the manufacturer couldn't provide any diagnostics that were specific enough to narrow the issue down. Of course I also underestimate the corrosive effects of living in the North Sea on electronic equipment and connections!
