A brave owner, but I love seeing cars like this getting used.

Interesting to see that there's very little common design language between the two cars. The Z8 felt much bigger and beefier in person.

Well, the drive to Islay is this coming Thursday, and what perfect timing for the Discovery's aircon to stop blowing cold, again. The system was gassed last summer, and still working into the winter. Since fitting the new condenser a few weeks ago, all of the gas appears to have buggered off sharpish. That's quite annoyed me, given that the specialist said there was only "a tiny leak" from the condenser.

Hopefully it's something as simple as a seal that's failed while being disturbed to fit the condenser. Either way, it's back to the Norfolk specialist tomorrow AM, with the goal of getting it back Thursday lunchtime at the latest. Not having aircon for the trip is not the end of the world, but I'm quite keen just to get the bloody thing sorted, and don't mind chucking a few quid at it with summer around the corner.

The Z4 is booked in for a few bits (two topmounts, two engine mounts, front RTABs) next month ahead of its Eurotrip. Looks like we're probably going to spend July in France (although unfortunately not Provence, as originally planned), which will mean taking the Z4 and starting/ending the Eurotrip there. Should be interesting to see MrsC pack a month's worth of clobber into the Z4 boot... hehe

ETA - also need to sort out the condensation in the driver's headlight, which has annoyed me since I bought it and is responsible for an intermittent indicator bulb warning (probably corroded terminals). Going to whip off the cover and chuck a sock full of dehumidifier crystals in there, and then see if I can't do a better job of sealing it back up.

Good news, and my idiot's diagnosis was half right. A nice change.

The condenser that was fitted three weeks ago had a manufacturing defect that prevented one of its O-rings from sealing, and didn't/doesn't show up on a vacuum test. So the garage are just chucking on a replacement this afternoon, and we should be good to go.

Free repairs are my favourite type of repair.

What an incredible machine the Discovery is. Just immense.



1500 miles in a week is quite a lot for an old, complicated car, and I can't think of another car at this sort of budget that could have completed it so effortlessly. From slogging 300 miles without breaks on the motorway, laden with 4 people and a week's luggage; to dragging 7 people and supplies up steep, rocky pathways to get to remote beaches - the Discovery just takes it all in its stride. Although the trip was not without frustrations, which I'll come onto in a moment.



Islay was, as ever, absolutely stunning. The weather was completely ridiculous, with barely a cloud in the sky for an entire week, meaning that plenty of beach visits and sea swimming were the order of the day. The whisky festival was, as ever, absolutely wonderful. Great people with a real passion for whisky, united through events, tastings and live music. Oddly enough, it's also a bit of a Mecca for Land Rover owners, which means you can often park alone and come back to find scenes like this. There were lots of far more serious LRs on the island, many of whom were Defender owners in various 'overland' configurations, and the Discovery tended to look like a glass of water in a cocktail bar next to such tough machinery.



We visit Islay with the same group each year, and stay in the same house - located up a brutal track, with stunning panoramic views of the island. This year, the group chose to bring their Defender up, and as you can see it very much looked the part. Aside from a dead battery, meaning that it needed to be pushed off the ferry, it gave excellent service throughout the trip. That said, in spite of it being both newer and more expensive than the Discovery, it's not a car I'd choose to spend 1500 miles in. Noisy, uncomfortable and unrefined service are, I guess, the payoff for something that looks so iconic.



On the subject of 'service', and coming back to my earlier comment, the Discovery performed dutifully throughout the week aside from two moments. The first was self-inflicted, and the second inflicted by a moron. I knew the (original, 18yo) front airbags were leaking slightly when I started the journey. It had been my plan to replace them before we left, but I simply ran out of time. The minor issue resulting from this was that we were met by a lowrider most mornings, where the airbags had depressurised overnight and the car had tried to level itself but ran out of adjustment. Annoying, but not the end of the world. The more annoying part was that three times over the course of the week I had the orange suspension warning flash up (only one bong, suggesting an annoyance rather than a catastrophe), signalling low pressure in the front airbags. A quick ignition cycle, and it disappeared. The second moment was more frustrating, as I came out of our Glasgow hotel on the return leg to find that some utter pillock had swiped the front arch in a car park and broken the fixings. Speed tape to the rescue, and we made it home without incident.



Time for a little TLC, I feel. The Disco is booked to go back to the local specialist for new front air-springs and shocks, and I may do the rears while I'm at it for peace of mind. I've also ordered a few bits of plastic trim to tidy up some little niggles - the front arch trim, the front towing eye cover (that Bambi broke last year), and the lock blank on the driver's door (which is a hideous piece of design). I've also been in touch with a company in East London about getting the largely useless upper nav/4x4 screen replaced with an Android Auto screen ( https://www.carsoundsecurity.com/Wireless-Apple-Ca...), which will enable me to get a reversing camera fitted at the same time. The last piece of the puzzle is to try and work out which CANBUS adaptor is required to enable the steering wheel buttons to control the unit. It's going to be a pricey addition, but should bring the car's tech right up to date and make it much more usable as a result.

I think this one is a keeper, so it's time to get the chequebook out...

Great to read the Discovery has acquitted itself so well on your tip OP. Amazing to get such good weather.

It's equal parts impressive and relieving, although I never worried unduly about it 'failing to proceed'. I guess that's a measure of a car you trust.

I notice you have a prefacelift L322, with the BMW petrol engine. I had given very serious thought to one of these, but decided I was looking for a later car for the interior updates. How is it to live with?

Yes January 2004 L322 with the BMW M62 4.4 V8 at this end. Lovely to live with - bought for £4,500 in Sept 2017 instead of spending £3k on winter wheels and tyres for the E350 daily driver I had at the time. Expected to do no more than 2,000 miles a year. In practice, I liked it so much and my wife and children liked it so much, we ended up doing 10,000 miles per year in it. Fantastic for holidays and towing a horse trailer. Just brilliant.

But in my experience over 44,000 miles (from 167,000 to 211,000) you do have to turn a blind eye to:
16mpg; and £3,000 to £5,000 pa in repairs and maintenance.

My running costs are probably a bit high, because I’m useless so almost all repairs have to be done by a garage. Then finding the right garage is crucial - I could have saved hassle and cost if I had cracked that earlier.

But overall, I love it. And with each new blacked out, parpy exhaust, low profile tyre’ed SUV I see, I like the L322 more.

That £3-5k annual maintenance budget is starting to resonate. I think there are two approaches to running complicated, older Land Rovers.
1. Budget. Wait until something breaks and the car leaves you stranded, then fix with the cheapest parts available.
2. Proactive. Identify weak points and fix before total failure with good quality or OEM parts.

I know having a car that failed on me regularly would annoy the heck out of me, so I fully endorse anyone going down the second route. The budget route is the reason I believe these cars have such a bad reputation for reliability. Watching people do coil spring conversions because they can't be bothered to diagnose and fix the air suspension is heartbreaking. The ride is sublime and a real part of the character.

For £3k a year, I can't think of anything I'd rather own.

So, a call from the Land Rover specialist. I was preparing myself to hear that I need 4x new air springs and dampers - not that I would have begrudged this, but it's a fair old chunk of cash. They've been checking the car on and off for 3 whole days, including leaving it overnight on uneven surfaces, spraying everything with leak detection fluid, and have concluded that there's nothing wrong with the air springs. They plugged in the specialist Land Rover suspension diagnostic machine, which apparently runs through a full series of checks on all components (cycling compressor/valves, checking pressure at all points), and found zero discrepancies from the factory figures.

It's a bit of a head-scratcher for them, and the guy who owns the garage called them an "absolute bugger". The only thing the diagnostic test did throw up was that the ride heights had been last set (before my ownership) at different values from the factory. He reset them, the rear dropped a touch (not that I'd noticed it being higher), and apparently it passed the diagnostic check with zero issues. He can't be sure that this caused the orange light and the bong, but "anything's possible with these bloody things".

They also spotted a couple of rusted studs on the centre exhaust join, which are beyond salvation, and undoubtedly the source of the 'tick' I've noticed on acceleration. They are planning to grind/drill out the studs and fit a bolt and nut instead.

Overall, less painful than expected. Hopefully the car rides (smoothly) again.

I had convinced myself to go down a path of tidying up the bodywork over the winter, alongside getting the tiny amount of rust sorted. But thinking more critically about it, it's never going to be mint and I really don't want to get to a position where I'm worrying about it getting scratched etc. Some of the plastic trims are starting to peel a little, suggesting that someone might have been in there with plastidip or similar in the past. No idea how to resolve that, but it's annoying me enough that I might decide to do it.



Came across this photo I took of MrsC driving it through Inverary on the way to Islay. She's finally decided that it's more comfortable and practical than the Volvo or the Z4, but it's a bit big and it doesn't quite meet her expectations on CO2 emissions. I'll take that as an overall win...

As for me, I'm still very much in the supporters' camp.

You're doing well with 18 yo airbags. I'd say they must be marginal by now?

This is what I'd prepared myself for, to be honest. I think the low mileage (116k) combined with it leading a charmed life with its only owner before me (he never took it off-road once, according to his widow), has been their saviour. There's money in the maintenance kitty for them to be replaced, but there's no sense chucking parts away if they are passing the diagnostics with flying colours and showing no visible leaks.

I'm still not 100% convinced the problem is solved, but that's half the fun with owning a LR of this vintage. It's almost certainly not going to let me down and leave me stranded (said in pure optimism), so I'll wait until I see further symptoms before worrying any more.

When mine was dropping at one end - occasionally overnight at first, and then eventually whenever it was parked for more than half an hour - it turned out to be rust pinholes in the reservoir. That was also a protracted diagnostic journey, but it might be worth checking.

I saw one of these with the V8 badge near Balham on the weekend. It always raises a smile when I see one.

The early Disco 3 is going to be a design icon but by God there's no way I could stomach owning one! Good luck hehe

So this was a question I asked too. There's very little surface rust on the underside, and apparently the tank pressure is checked as part of the suspension diagnostics they ran.

That said, if I'm reading the various technical documents properly, when the ignition is off the three valve blocks should 'lock' closed. This would mean that dropping overnight can technically only be one of a handful of things.
1. A leak in an air spring
2. A leak in the pipework between valve blocks and air springs
3. A failed valve block
4. Something odd going on with the sensors and self-leveling system (the system checks the level every 30min with the ignition off and lowers until the car is horizontal)

These are funny old things. I guess this complexity is the cost of having a car with both magic carpet ride and ridiculous off-road ability. I love this promo photo showing how hilarious the standard articulation is.

The V8 is (quite literally) vanishingly rare. They only sold a few hundred, and the engine option was dropped altogether after a couple of years, because the 00s was the period when diesel SUVs were in vogue, and many buyers couldn't stomach the cost of fuelling the V8.

Howmanyleft suggests there are less than 300 V8s left on the road (c.200 in my HSE spec), which seems like a reasonable level of attrition for an 18yo car. Unless you really needed the extra space, then I'd imagine the vast majority of petrol buyers would have simply bought an L322 at the time.

Fortunately, I probably need less luck running a petrol version (fuel costs aside) than a diesel. Some of the packaging on the diesel version was very marginal, and a number of the bigger maintenance jobs (typical for cars of this age) require a 'body off' service. The pictures are petrifying.

Clarkson, a staunch Land Rover advocate was, perhaps unsurprisingly, quite complimentary of them when new. He rightly calls out some of the compromises (the weight, the performance, the rear seat access etc.), but his conclusion about it being the sweet spot between the "luxury" of a Range Rover and the utilitarianism of something more agricultural hits the mark for me.

https://youtu.be/QznF1tiG6vc

I do wonder sometimes whether I'd have enjoyed a different ownership experience with a supercharged L322. But then the moments when I'm loading a huge piece of furniture or a pile of recycling, or carrying 7 people along, make me think I probably made the right call on balance.

I've enjoyed reading your Discovery endeavours - shame the 4 didn't get a V8 in this country! I'd say you got quite lucky with the rear A/C pipes being fine, as apparently it is body off to replace them!

They are such a deeply impressive vehicle in so many ways

Likewise, I'm envious of your attitude to maintaining your D4 yourself. I don't really have the time or facilities (not keen on jacking up 2.5T on a gravel driveway) to do any major work myself, so I'm at the mercy of the specialists. Luckily I've found one that seems decent enough a short drive away from home.

Thank you smile I've always liked to tinker, although sometimes it is bourne out of necessity. The thing that truly scares me on these is anything body off, as I don't have a 2 post lift, just a driveway haha. I saw someone on the Disco 3/4 facebook group did it using tall axle stands and some planks of wood, but he must have bigger stones than me to do that

Fun fact. The Discovery can wade to a depth that would have water pouring over the top of the Z4's door. They are very different cars. laugh



Dropping the BMW off for its pre-Euro titivation on Friday, and heading straight over to collect the Discovery. I'm away with work next week, so the Z4 is booked in for an aircon top-up (it's definitely cold, but not freezing) and re-alignment the following week before I set off on the Saturday morning.

Officially starting to get a bit excited now. Plans can be found here: https://www.pistonheads.com/gassing/topic.asp?h=0&...

After Stuttgart I'm heading over to the Ring, where I'm hoping to squeeze in two evening sessions as the track is closed for testing during the day. I definitely want to take the Z4 out for a couple of laps to see how different it feels to my old Mini there, but I'm contemplating renting something from one of the local companies on the other evening. Either that or I'll book a passenger lap in something ballistic.
