I'd concur with @sierrafery. The fuel filter often gets forgotten, largely because of its location. I change mine at the annual service, along with all the other filters and engine oil change.

You're probably going to have to consult an "In-Car Entertainment" specialist about that. The Disco system is analogue, switching different values of resistance, whereas more modern systems are possibly digital.

It can depend on what vehicle you're intending to fit a steering lock to, some devices will suit some vehicle types better than others. It could also depend on whether you particularly want to deploy "covert" or "overt" systems, that's hidden or highly visible devices. Take a look at @ratty's...

If I told you that on an open forum, I'd have to kill you!

Be aware that while M+S tyres are quite usual for UK weather, true cold climate or winter tyres will not only carry the M+S marking but will also have the "Three peaks and a Snow Flake" logo on the sidewalls:-

You say that you're in the market for three tyres. You might get a better deal if you look for a "special" offering a package on a set of four. Regarding delivery, the first time I used an online supplier I had them delivered to me at home which left me with the slight problem of getting them to...

When winter or cold climate tyres started to be introduced and used in the UK, some insurance companies didn't quite understand what was going on, with the result that they classed fitting them as a modification and consequently loaded the premium. These days at least they understand that winter...

A web search for winter tyres will most likely turn up loads of adverts from tyre manufacturers and suppliers, so I've tried to pull together a couple of sites which essentially have no tyre related product to push, the RAC, the AA and Which. All state that the temperature at which winter tyres...

@gstuart One for you Gary?

The only way to definitively diagnose what's causing the 3 amigos is to get the codes read using a compatible code reader. Just because you've "sorted" one problem, there's no reason why it couldn't be a new, different fault causing the lights. "Poke and hope" will just cause you frustration and...

Sipes are generally very small "cuts" on the contact surfaces of the tyre, often in a zig-zag shape. Because they are so small, it's unlikely that you'll see them on a photograph of a tyre unless the fact that they are present is highlighted. In most cases you're going to have to physically look...

I change over to cold climate tyres usually in November, just watch the weather forecast and temperature predictions, and change back to "normal" tyres in late April/May. There's no need to tell your insurance company. You can try, maybe to attempt to get a discount but that's most unlikely. As...

As a Disco 2 owner, I can't comment on the D4, but Gary (@gstuart) has done a buyer's guide for the Disco 3, some of which could well apply to the D4 too. https://www.landyzone.co.uk/land-rover/buyers-guide.312800/

I don't wish to start an argument, that's furthest from my mind. In the case of air suspension, I've based my advice on the fact that the air springs are the items which are under the most mechanical stress and therefore most likely to fail. They are also liable to failure due to age, hardening...

There are a number of faults which can afflict vehicle loudspeakers, usually the effects of damp air causing rust particles in the magnet air gap, or causing damage to and distortion of the paper cone. Age can also cause the outer edge of the cone to become detatched from the main frame, either...

It's not the oldest thread we've seen today. :confused: Regarding changing the amplifiers and the resultant frequency responses, I wouldn't know, but do bear in mind that it's a Land Rover Discovery, an aluminium and steel box on wheels not some finely tuned audio theatre.

Dunno if it's a record, but it's certainly a contender for the thread revival of the year award.

When were the bags last replaced? Bags can be expected to last about five to seven years and can throw up some weird behaviour when they're beginning to fail. As the rubber hardens small cracks can develop especially where there are folds in the bags. These can seal themselves up for days or...

Before you can even start diagnosing problems on the Disco 2, you're going to need a good battery. you'll need at least 10.5 volts while you're cranking the engine. Anything less than that is going to give you all sorts of erroneous results. If you suspect your alternator is at fault then...

I wish I hadn't read that. The picture in my mind's eye of @neilly in a wet bikini is something that's going to take a stiff drink to forget! :eek:
