M54B30, yes

As always with the E46, coolant system can fail in various places, usually around the 100k mark, potentially leading to the engine overheating and warping the head

Water pump, expansion tank, radiator, thermostat are all prone to problems. Most important thing is engine off immediately if the temp goes past halfway. Some suggest replacing water pump / thermostat.

Apart from the door surrounds looping off, I didn't have any issues with mine between 37k and 107k, when I sold it.

It drank oil though.

Nothing to be greatly scared of though (apart from warping the head) - replaced my radiator, water pump and drive belts for just under £100 all in. Pretty easy DIY job, the car is well designed for servicing and comes to bits easily. 4hr job and 50% of the time was reading the haynes manual.

Do a bit of a search about rear subframe mounts. I'm not sure when this was rectified, but there was a batch of models which had issues with the mounts tearing out the boot floor.
