Hey Dave Thanks for the welcome and quick reply! While the car is running it is smoking, idling and while on throttle. About the coolant, it's some black residue mixed with the coolant on the expansion tank. I checked it and it wasn't oil, looked a lot like melted rubber/plastic, but I did not notice any major leaks nor massive loss of coolant. I will take a look at the site that you recommended. Once again, thanks!

Hello Guys, I'm new to the BMW world, and I'm facing some issues that some say might be quite expensive to fix, but the symptoms don't seem to match. I would love to get some feedback from some more experienced guys like you! So, I currently own a BMW E46 320d 136hp, bought less than a month ago, and the car is driving ok, with no issues starting or idling. The previous owner did lengthy maintenance and replaced common wear and faulty parts, but I'm currently noticing some white smoke from the exhaust. I've noticed some coolant disappearing and some gunk building up but it isn't oil mixing, I don't notice any power loss or extra consumptions. Some say it might be a mixture of coolant in the engine, maybe a cracked head or a bad gasket, others say it could be the turbo bushing or seals and I've also heard it could be the injectors. Do you guys have any recommendations or advice for a newbie like me? Thanks in advance!
