Jam the handle of an ordinary workshop hammer between the exhaust and
the rear right differential.  You'll see where one of the Allen screws
shows signs of wear on one edge.  Loosen and retighten the exhaust clamp
between the centre and rear sections.  Remove hammer and charge customer
$80.

The MB is volatile - stored codes are lost when the ignition is turned
off.  Spin it for five seconds and leave the ignition on.  Ten gets
you one it's a flywheel sensor problem - nearly always is after a
rebuild.

No, there isn't on an MB.  Stick a fuse in the fuseholder on top of
the fuel pump relay and switch the ignition on.  The pump runs after
four seconds.

It might on a WR.  Not on an MB.  Your learning curve is only starting.
