Subject: E28 M5 Starter Replacement
Here's how to change an E28 M5 starter -- I did mine yesterday.
The starter itself is the same part as a regular E28 535i, but
different things are in the way on the M5 engine.
- Disconnect battery.
- Remove air flow meter boot from driver side of intake plenum
- Disconnect small hose between the bottom of plenum and the
crankcase near the oil dipstick (hose clamp).
- Disconnect two hoses on passenger side of intake plenum
- Remove twelve cap nuts and washers from intake throats
(10 mm wrench).
- Unclip plastic holders at ends of throttle cables.
- Pull intake plenum out without disturbing the six rubber boots
on the passenger side of plenum.
- Starter is now in plain view. Cut the two cable ties which
hold the starter solenoid rubber cover.
- Remove cables from starter (13 mm wrench).
- Hardest part -- it takes a while and needs a special wrench
because there is no room for a normal straight wrench or socket.
Remove two starter motor bolts with a special u-shaped
17 mm obstruction wrench (also called starter or half-moon wrench).
It's tough to find these wrenches in metric sizes. Try Snap-on,
Mac Tools, or Griot's Garage. Sears only has them in inch sizes.
- Assembly is the reverse ... two new cable ties needed for the
starter solenoid rubber cover.
Part Number Description Price

07-11-9-924-324 Cap Nut M6 $ 2.82

The cap nut and flat washer are from the intake throats.
I seem to lose one each time the intake plenum comes off.
