    Not sure if I'm posting this is the right section??

    But I just picked up a new Merc W220 (S430L) today and it has quite a few issues to sort. But for now I've just got some bulbs to replace, tyres ordered and also ordered some rear brake pads... will have a busy weekend I think!

    But one thing I am curious about, the tailgate opens from the remote fob, but although the handbook (I've downloaded one online as it came with none...) appears to suggest it should automatically raise, it just opens and sits on the lock?

    Do all W220 tailgates raise automatically? Or is this just an option?

    Do check that both springs are OK, is it heavy to lift up

    Yes it is quite heavy to lift, also a bit heavy to close.

    The springs either side are very funny looking, I'm used to a 2003 Jaguar XJ which was actually rather basic compared to this, despite being much newer. The jag XJ just had two thin gas struts where as this also has some covered springs.

    Should the springs be lifting the boot?

    If it has the option of auto boot it may need normalising which is why it feels stiff to open and close as it is being forced against the motor

    Right, think I am on to the bottom of it now...

    Serves me right for only looking at in the dark, after work. When I finally looked properly it was obvious that it was spring loaded (and not powered closed).

    After lots of WD40 and then a wipe and some grease - I finally have an auto opening boot again!

    Thanks for the help guys.
