BMW E46 Expansion Tank Cracking. One of the primary areas of issue for the BMW E46 cooling system is the expansion tank. This is actually a very common issue on most BMW’s up until the late 2010s due to the material used for the tank itself. Both the BMW M52TU and M54 used a plastic expansion tank that had thin walls and was prone to damage.
Symptoms of a Cracked M50 Expansion Tank. Coolant leaking around the expansion tank. Low coolant levels, or having to replace coolant frequently. Engine overheating due to lack of coolant. Replacement options: the OEM tank is made of plastic, which is one of the biggest faults and reasons for cracking.

Potential coil problems, post here. Some of us have probably heard of a possible problem with some of the coils in the 3 series. Audi had a bad rash of poorly made coils which required extensive coil pack changes in Audi's and Volkswagons. The 3 series is starting to show some of the same problems, or so this thread would like to see if that is so.
If the exhaust sprocket driver teeth are broken then that is the fault. If the teeth are still present then the solenoid pack is the fault. Although the BMW ETK (parts catalog) shows the vanos solenoid pack is discontinued, it is available under a new part number, 11-36-7-839-180, $600-$700. The BMW M3 is one of the most thrilling and one of the finest sports cars you can buy used. Terrific speed. Immense cornering capabilities. Well equipped. Road noise. Engine note a little rough
