Hey man, i had the same problem with my 325i (clankins sound on cold start-up) i took it to the dealership to have a look they diagnosed it wrong telling me a pulley is cracked and quoted me a ridiculous amount to fix it so, i decided to have a look 4 myself and i found that a pulley was loose the pulley looks similar to that of a cog of a bike it has 1 bolt in the center, that bolt was loose so all i did was tighten it and it solved the clanking sound , give it a shot it might work for you.

Its very likely your water pump. But I would recommend you start by flushing the coolant in your engine, add some coolant flush to the coolant before you flush it. Make sure the coolant flush is compliant with your engine type. I would advise changing your thermostat as well. This has in many cases resolved your type of problem.

If your car is shaking while it's on but not actually moving, then it's likely not the tires. This usually means there is something broken in the engine, such as the radiator fan or engine mounts. Fuel system issues can also cause the car to shake even while standing still.

BMW 323i 1999 takes a long time to start in mornings and after short layoff. Engines seems not to want to crank. Battery OK. Changed sensors, fuel pump & relay. Dealer cant find fault. Starts after...

Friend, you've changed everything but the right thing. The temperature sending unit. It tells the computer to go into cold start mode to start the engine by putting more fuel into the engine. If this sensor is erratic, sometimes don't work, it will cause a hard start situation if not in cold start mode. Dealer cant find this because it's a manual thing and may not be showing up on his tester.
