    Many of the electrical problems on the Td5 Disco 2 are the result of moisture ingress, either because of condensation, bodywork leaks such as the sunroofs or driver error; thinking that the Discovery is amphibious and not just a 4x4 "go almost anywhere" vehicle.
    Condensation and leaks can be sorted out with care and regular maintenance, I'm not sure about the third problem.

    I got very "anoraky" about electrics and moisture a while ago.
    Mainly because of a work project involving us installing battery powered systems that had to be water tight at 2m depth for two years!
    Did a lot of research, the US military has loads of good info all free to download.
    Ive also found that some protective sprays are better than others, WD40 is not always the best, it can attack some plastics/seals and actually cause connectors to leak!
    The trick is to first clean the connector and contacts, IPA spray is best, but I also use "Kontakt 60". from RS #823-5329
    You can buy IPA from Amazon, get a big bottle of it, much cheaper than the little tin of "MAF Cleaner"

    Then you need to protect and lubricate the connector.
    Ive found "CRC 2-26" works well, I get it from RS #780-5329 costs around £12
    Ive sprayed all my underbonnet connects with these and so far not had any issues.

    Hi when looking at D2 TD5s obviously the first thing to check is the rear chassis... Don't be shy have a good poke about... Also under the bonnet peal back the sound deadening at the bulkhead and check there... Also check it starts well from cold, make sure you ask the seller not to start it that day... Don't wait for heat, ignition on wait 2 seconds then swing it...if it starts easy and spring into life This gives a good indication of engine condition

    By IPA I assume your talking about Isopropyl alcohol. Would paint pre wipe be as good? 5L tin is as cheap as chips.

    Some really great advice here thanks all. Any comments on the 'milage points' issue, or is it just a case of look hard and hope for the best!?

    Any Disco 2 is now going to be at least 13 years old, so using the usual "standard" mileage for a second hand vehicle, I'd say that if you find one with fewer than 130,000 miles on the clock you're doing OK, just as long as everything works as expected.
    TBH at these sorts of ages, actual condition is of more value in deciding than service histories or mileage.

    Finding one that hasn't been welded will be hard to come by nowadays... But look hard enough there about!

    An MOT history check will tell you if its ever failed for rust, hence been welded.
    Some are still ok, mine is, and its for sale!

    Yes its alcohol, get the highest % though, some on Amazon is only 50%.
    Not sure about paint prewipes, not used them.

    This looks to be a really handy the address for when I start looking for a Disco 2 in a few months.

    Hi..no, it was about a pint of what looked to be Everards Old Original...although I can't say it tasted the same when I got a face full...there was a lot of Waxoil that I had to dig through (once I got the plastic grommet out) with a length of wire.
