    Long story but can anyone tell me where the positive terminal is under the hood please? Can't get in boot (mechanical key doing nothing) and nothing coming up on dash.

    Is there a safe place under the bonnet I can connect doner car?

    (This is my mums petrol 211, 52 plate. Doesn't have an easily identify + point under the hood like my S211 has).

    Thanks for any help.
    Shr.

    there is none open bonnet der the fuse box its on the drivers side(drivers side sam) you find big red lead and a 13 nut on a lead put 1 the postive lead on there and put the negative on any earth and just use your key to open the boot and then you can jump start the car

    Yes did see that and thought that would work but didn't have the nerve to try it in case it was not the right place to do it and ended up frying control modules etc.

    So it's ok to use that then?
    Anyone else care to confirm?

    Does it not tell you how to do this under " battery" in the owners manual?
    here's an excerpt from the USA manual.

    3. Lift cover (1) and clamp one end of the first jumper
    cable to the positive (+) under hood terminal (2) of
    the discharged battery and the other end to the
    positive (+) terminal of the charged battery. Make
    sure the cable clamps do not touch any other metal
    parts.
    4. Clamp one end of the second jumper cable to the
    grounded negative (–) terminal of the charged
    battery and the final connection to the negative (–)
    under hood terminal (3) of the disabled vehicle.

    Important!
    5. Start engine of the vehicle with the charged battery
    and run at high idle. Make sure the cables are not
    on or near pulleys, fans, or other parts that move
    when the engine is started. Allow the discharged
    battery to charge for a few minutes. Start engine of
    the disabled vehicle in the usual manner.
    6. After the engine has started, remove jumper cables
    by exactly reversing the above installation
    sequence, starting with the last connection made
    first. When removing each clamp, make sure that it
    does not touch any other metal while the other end
    is still attached.
    Note:
    If engine does not run after several unsuccessful
    starting attempts, have it checked at the nearest
    authorized Mercedes-Benz Center.
    Excessive unburned fuel may damage the catalytic converter.

    NOTE CAREFULLY 1.the connection order of the jump leads e.g. +ve lead.different sequence to negative lead. and 2. charging the flat battery for a few minutes via the "donor car" before attempting an engine start on the flat battery car.

    Thanks for the procedure, I'll follow this.
    Didn't think to look in the book.:doh:

    Trouble is, there isn't a clearly identifyable (+) point under the hood (or not that I can see, anyway). I'm hoping people here will tell me which point I can safely use.

    This is my Mum's car. I'm not there anymore, will have to go back next weekend, hopefully armed with an action plan from you guys, to see if I can get it going.

    Has she/the car got Mobilo? Is so they will come and sort it (I think?)

    Should be a pic in the OWNERS MANUAL which might be slightly different in a RHD car from this USA pic.

    Will have to check the manual but there definitely isn't a flip-up lid marked with a + as the above image suggests.

    OK well this is a little embarrassing.
    In my opening post, when I said the mechanical key was doing nothing in the boot lock, I didn't realise you had to pull the handle too. :doh:

    With the key turned, as soon as I operated the handle, the boot popped right open.

    As you guys suggested above, I should RTFM.

    (Head well and truly hung in shame.)
