Did you replace the spark plugs with the same brand recommended by ? Might also what to go over all the wiring harnesses, you disconnected when replacing the exhaust. Might of pinched a wire.

Get an owner's manual to be absolutely sure. 318i e46 too nice a machine to screw up...

Hi dear40,

The m43 engine should be similar to both the m42 and m44. The cylinder head torque settings are 22ft/lb and 90degree torque angle, and another 90 degree torque angle. Make sure to wait approximately 10minutes before performing the 2nd torque angle.

probably a bad air/flow sensor, try to clean it with sensor cleaner, its by the air intake filter box. if not clean the throttle body really good.

pls vote.

Either the fan switch on the engine or the fan relay is at fault. Replace both for they are inexpensive to replace

sounds like a blown head gasket

The engine coolant temp sensor is in the cyl head that tells the computer the engine temp.

Engine tempature probe on block is bad and grounded inside, or the wire leading to the engine block heat sensor is shorted to ground.
