ck 4 corrosion or bad blub.

Either the speaker is blown (most likely) or there is a loose connection to the speaker, or the amp is bad. The connections to the speaker are pretty tight and it's unlikely it came loose unless you recently had some work done near the head unit or the radio, and if the amp works well for all other speakers it's probably OK. Unfortunately you can't fix a blown speaker but you can replace it and you can find a new one online for less than $100

P1351 just means there is a misfire. Was there a note next to the code stating which cylinder(s)? I would start by replacing the spark plugs, there could just be a fouled plug. If that doesn't help, pull the ignition coils and boots and see if there is oil in any of the spark plug tubes/boots. If there is, you need to replace the valve cover gasket.

Hello everyone, please forgive me for the question but i honestly can't seem to find the answer to it. I want to change my fuel pump relay in my 2003 745Li. If I'm not mistaking, the fuel pump relay is located in the trunk next to the battery. I did notice the green cube looking thing (fuel pump relay) in the trunk but there were two of them. Do i need to purchase two fuel pump relays? Any insight would be greatly appreciated. ??

Might be a loose fuse or connector. Try wiggling the fuse and/or wires leading to the fuse box.

This is usually caused by the crankcase vent valves leaking air. These valves are round and sit on top of the front of each valve cover at the front. The diaphragm leaks and causes a vacuum leak and the car runs rough.
