    Just had a few days holiday in Northumberland. Just before setting off there was a warning of low coolant level which I've never seen before. No sign of a leak that I could see.Put in a couple of litres of water. Drove 200 plus miles, and a little local driving, got the warning again. Filled it up again, and a few days later drove back home.
    Must be going somewhere but can't see where. Hope it's not the head gasket.
    Whilst up there, got another warning. Can't remember the exact wording but something like "Drivetrain problem, full performance not available, drive moderately, and get it checked out".
    This appeared and disappeared 3 or 4 times over about 10 mins, and then disappeared for good, not seen it since.
    It pulled the glider trailer there and back with no problems, everything seems quite normal.
    Any ideas?

    Water pump weeping/leaking? There's a small hole on the underside of the pump [at least on those models I'm familiar with] which drips water if the pump gland is on the way out. Difficult to see, but run your hand across the underside and it's often wet.

    Drivetrain warning, could it be down to tyre pressure(s) or uneven tyre wear? o_O

    I had the low coolant warning once, topped up with half a litre and been fine ever since. Can't speak about the other warnings as mine doesn't tow anything other than my lardy ass about ;-)

    The Drivetrain warning is a generic message, can cover a host of different issues. I've had it previously, in my case it turned out to be a faulty turbo wastegate actuator, replaced under warranty, was told it would have cost £750 otherwise.
    It will be stored in the fault memory so best to get the codes read.

    I've no idea about the Drivetrain warning, but as far as the coolant goes, did you check the expansion tank when you got the low level warning? If it needed a couple of litres, I assume that it was empty. As it needed topping up shortly after, it points to a substantial leak - possibly water pump as @slim_boy_fat suggests. I would be straight off to a dealer or repair garage and ask them to do a pressure test. That should hopefully pinpoint where the problem lies. Also keep a close eye on the temperature gauge - if the engine overheats it could be very expensive.

    In my ignorance, I should have RTM, I put too much water in. Never had to do it before. After getting home yesterday, just checked the level and it is still above max, no drips on the garage floor, can't feel any wetness under the pump.
    BTW, when the drivetrain message appeared I hadn't got the trailer on the back, and was only driving very gently at about 40mph, heading for Lindisfarne.
    Anyway will get it checked out by my indy.

    I am one of those strange and rare people who does usually read manuals, but in this case the levels need you peer inside a dark container with a torch, which I didn't do. In most cars I have owned the expansion tank is translucent, so you can actually see inside, not opaque black plastic. BMW please note!!
    And the missing letter was deliberate, also being a very polite bloke, usually.

    Mine just has a yellow piece of plastic inside the expansion tank with 'Min' and 'Max' levels marked

    My E90 was black with a float but AFAIK they are all translucent these days.

    If not I could always raise it at the next shareholders' meeting. ;)

    Mine just has the bit of yellow plastic with max and min. There must be something to show if it is too low.

    Weekend was checking over son's Land Rover , water, ensure its cold , twist radiator cap off ,if required refill until it goes down the overflow pipe, cap back on.
    Oil simple dipstick.
    If only life was still that easy , but they didn't have a computer installed when they made that in 1952.

    Whenever I buy a new piece of technical equipment, I look forward to digesting the user manual. It's one of the pleasures in owning a new car etc. Plus it helps in knowing what all the knobs and switches are for. I accept that I may be a sad, old git, but "Hey, Ho" I just don't care! :D

    I admit the modern car is an extremely complex bit of gear , but I do find the size of the current manual a bit daunting for a read through ---- just use full as a reference when specific info is required.
    Recently tried to reset clock on the DMax,after 5 minutes found I had to refer to the radio handbook.
    It does annoy me when no manual is supplied , just reference to a web site.

    I still haven't got all my 'favourite' radio stations, seat settings etc stored in the spare key memory, and I've only had the car 31/2 years.......:oops:

    You'd think it'd be straighforward, no? :cautious:

    Don't you just lock the car with the spare and all the current setting are then stored on the key?

    I also thought this. I then opened the car with the spare key and used it for the next trip. Looks like both keys and the settings in the car are now the same.

    Don't have one of those now, but the spare is still set to the last owner's missus.

    Thanks, lads - I'll try the locking thing later. (y)
