- Turn climate control to highest temp & switch fan on to lowest speed setting
- Start engine
- Remove expansion tank cap
- Slowly open bleed screw until it stops bubbling
...and this is a tried and tested method that you've used?

Yep. Done on about 5 e46's including mine 3 weeks ago.
*edit* Just read that yours is a diesel so should be the same? Only ever bled the systems on petrol e46's

I think it's the same...the only thing that gets me is switching on the engine with expansion cap off!
just done it, no bubbles came out when i loosened the bleed screw..
I replaced both 'stats on my 330d a few weeks ago.
There are three bleed screws on mine. One on the expansion tank, one on the pipe leading to the EGR stat, and one on the EGR stat. My procedure for bleeding was as below.
Note: Car must be cold to avoid scolding.
1. Open up all three bleed screws and remove expansion cap
2. Start car (don't be scared, but keep hands away from moving parts
)
3. Fill the expansion tank right up past max until fluid starts to come out of the expansion tank bleed screw, close the bleed screw.
4. Keep filling until fluid comes out of the bleed screw leading to the EGR stat. Once you see fluid, close the bleed screw.
5. Repeat until fluid comes out of the EGR stat. You might need to put the expansion cap back on and compress the coolant pipes to get it moving.
6. Take the car for a long drive at motorway speeds, varying revs and get the car up to full temperature.
7. Leave the car to cool down fully, check and level the coolant.

Great thanks! It's a E46 facelift touring auto. 2004 with the 204bhp engine.

The EGR thermostat is far easier to actually get to and replace, it also appears to be the more likely culprit.

Mine goes off centre in my 330 when going up or down hills weirdly enough.
The temp guage in all but the M3 are damped anyway, I don't believe they're hugely accurage other than too cold, and more worryingly, too hot

The thermostat in my newly acquired 330ci was shot, pretty much open all the time, replaced it and it gets up to temp fine.
A good way of properly monitoring the temperature is to hold the trip reset button down for 10 seconds with ignition on or engine running, then keep tapping it till it reaches 19, then let go, it'll say off then tap it again until you see 7, release and the temp will be on the right, 0093 = 93 degrees c.
Other things can be done, just google hidden menu E46.
