Updates from today: 1) Power Supply (B+) reaching X60003/1 from fuse F4 - yes. 2) Power Supply (B+) from DME Relay, getting to DME at X60003/2 via fuse F37; -- yes, but that the DME Relay is not being activated to make it work. 3) Ground connection of 4 Brown wires to Chassis Ground Point X6454; -- yes.
Electric issues. Last but not least, the BMW F30 also experiences electrical issues. This can include the car’s lights, electric windows, or even radio. Always ensure the wiring is okay and the fuse is not blown. Also, you should inspect the check engine light and ensure that it does not give a wrong signal.
On more modern vehicles like the BMW E90 (Visit our BMW E9X Owner's Hub), one ground cable connects the driver's side engine mount bracket to the body. These engine ground cables are secured with 13mm nuts. Replacement is as easy as removing the nuts and installing a new cable. We hope this quick guide was helping in diagnosing your start-up woes.

Of course you only need half that in coolant as you will be mixing it 50 / 50 with distilled water. Do not under any circumstances use ordinary tap water or mineral water. On average, the annual maintenance cost for BMW cars is roughly $1,000. The figures can easily balloon up for the high-performance models of the brand. On the side of BMW though, it promises up to 200,000 to 250,000 miles for its xDrive-equipped vehicles. The numbers come with the consideration that the vehicle is properly maintained and driven
The N47 engine started to be used around Feb/March 2007 but the M47 engine continued to be fitted in some cars until Feb 2008. The problem with timing chain failure was solved on N47 engines fitted to cars with a build date after April/May 2010. From April/May 2010 up until April 2011 slight noise issues with timing chain persisted on the N47
Quite literally.. sometimes when i start it it will crank right up and start no problem. Then I can literally shut the car off.. go into a store, and come back out and it seems to have a real hard time cranking over. Sometimes in the morning it has a hard time starting, and then other times it cranks over perfectly fine. It has a bizarre problem that my mechanic has yet to resolve. When the outside temperature drops below ~36F, the car will not start. The car cranks and cranks and cranks but fails to start. After repeating the process for 5-6 times the car will intermittently try to start but idle rough and die. If I continue repeating the process 5-10 minutes Wrong oil: Using the wrong engine oil in your BMW can cause various problems. However, the timing chain is one of the major parts that will be affected. It will likely wear out faster if you use the wrong oil. Chain tensioner or guide problems: The chain relies on guides and tensioners to stay in place and work properly. If there is a problem Check rear trailing arm bushes. Check handbrake shoes. Check front wishbone joints and bushes. Check the turbo actuator vacuum pipe that runs from turbo to valve to accumulator then up over the

I drove home from dealership (5 miles) and when I went to start it the next day the coolant light came on. Checked and couldn't even see the float and proceeded to add 3+ cups of coolant/water mix.
