1. Vibration. You need to check fuel injectors and clean them in case of necessity.
2. Rough idling. This problem is caused by idling valve and throttle flap. You only need to clean them in order to avoid such problem.
3. High fuel consumption. You need to check air flow meter as it can be the main cause of the problem.
At the same time N13 doesn’t like often change of motor liquids. At the same time you need to change them regularly. High quality gasoline is recommended as well as motor oil prescribed by BMW brand. If you proceed with regular checks and maintenance you will hardly face any problems.
Affected Vehicles:
Common failing part numbers:
F20 , N13 Engine, Cut Out, Non Start
To no surprise we had another BMW 1 Series recovered in, EML come on, had cut out and now won’t start – here’s what we found, how we went about it and what the fix turned out to be.
毫不奇怪，我们又找到了另一辆BMW 1系，EML来了，已经淘汰了，现在就无法启动-这就是我们所发现的东西，我们的处理方式以及最终的解决方案。
113026 Injection relay and injectors, supply voltage, fuel injection: circuit short to ground.
113026喷油嘴继电器和喷油嘴，电源电压，燃油喷射：电路对地短路。
1F0514 Valvetronic supply voltage: circuit short to ground.
1F0514 Valvetronic电源电压：电路对地短路。
1F0515 valvetronic supply voltage: open circuit.
1F0515 Valvetronic电源电压：开路。
The faults were permanent, as soon as cleared they all come back.
这些故障是永久性的，一经清除，它们就会全部恢复。
A quick look at the wiring diagrams
(Check out my previous post for free diagrams) showed us that the ignition coils, injectors and valvetronic system is all wired directly to the DME. A check of the wiring revealed no obvious issues. Possibly the DME could be faulty, but no one wants to jump straight to an engine #DME!
快速浏览接线图
（查看我以前的帖子以获取免费图表）显示了点火线圈，喷油器和Valvetronic系统都直接连接到DME。 检查接线没有发现明显问题。 DME可能有故障，但是没有人想直接跳到#DME引擎！
