2005 BMW 745Li Automatic - Answered Questions & Fixed issues

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. ??

You will need to use an appropriate scan tool

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.

So your off to a dealer or trans shop Went into fail safe for a reason

Drive it a few miles

probable clutches slipping

If you have a multimeter remove and test the fuses for continuity (OHMS) as fuses can look OK but they have blown. If your replacing fuses ONLY replace the with one of the Same colour and Amp rating.

Yes, Bimmerfest Forums are a great resource. https://www.google.com/search?q=BMW+325ci+vacuum+hose+diagram ..

Question edited for clarity. changed your Poly Vinyl Chloride (PVC) into Positive Crankcase Ventilation (PCV), and added some punctuation to make real sentences. Your car is run by computers, the computers have diagnostics and will tell you what's wrong. You can't guess faults like you have. A Professional Grade Scan Tool computer can diagnose all the computers, modules, sensors and systems in about 40 minutes. It can even record what happens and what goes wrong as you are driving! https://www.google.com/search?q=mobile+auto+electrician+near+me ..

To turn off HDC on a BMW, all you have to do is press the HDC button located on the center console. The button will have an image of a vehicle going downhill with a speedometer above it, and you'll know it's off if there are no lights illuminated above it. If you ever want to turn the system on again, just press the button again.

Since you fixed the fault by scan advice and was ok and on testdrive another limp mode came up, just check again with your scan to see what is the possible cause for it. Probably the crank sensor.

6 years different and a different series? If only life was that easy! Some BMW have a mechanical pump driven by the serpentine belt, and some have an totally electric powered pump. Just buy one for the model you have. https://www.google.com/search?q=2012+BMW+535i+water+pump or https://www.google.com/search?q=2006+BMW+330i+water+pump Rock Auto are a good suppliers, have images and different makers and 'qualities'. https://www.rockauto.com/en/catalog/bmw,2006,330i,3.0l+l6,1431850,cooling+system,water+pump,2208 ..

Check the basics first. Is battery fully charged? This is the most common reason for a no crank, no start. What exactly does it do when you turn the key? Nothing at all, no lights, no 'click' as you turn the key. A slow lazy crank?
