How to install joomla in wampserver step by step pdf pdf. If you are one of them who drives BMW with N43 and/or N53 series petrol engines, the most likely you have experienced rough run, misfires and never-ending stories with injectors, spark plugs and ignition coils replacements. In our blog, we reveal most popular and well-hidden cause of these problems. We also provide cost-effective and long lasting solution. Search for: We recommend to start with article who describes sentence: The most woe of N43/N53 series engines: uneven operation – is well known to all interested, enthusiasts and repairers. Yes, sometimes spark plugs, ignition coils and injectors are ones to blame.
But one tricky cause is hiding, and nobody mentions of it. What it could be? To each BMW enthusiast, we offer Online diagnostics for N43/N53 engines. What does it mean? When all major problems (including NOx system) are solved.
CAN Bus Description. The Controller Area Network (CAN) specification defines the Data Link Layer, ISO 11898 defines the Physical Layer. The CAN bus [CANbus] is a Balanced (differential) 2-wire interface running over either a Shielded Twisted Pair (STP), Un-shielded Twisted Pair (UTP), or Ribbon cable.
Most popular reasons of uneven run. 3104 Summary. How to handle the situation, when N43/N53 has started to shiver.
In this entry: step-by-step diagnostics of, possibly, one of the most complicated engine management system of all times. Each of stages is kept as short as possible, references to previous posts for much more detailed information will regarding each knot/ theme be inserted. NOXEM 129 130 Installation. NOXEM 402 Installation. Unfortunately, quite often the diagnostics, performed by “specialists”, is limited by reading the error messages and replacing all components, indicated in the error messages. Entries relating NOx system – NOx catalytic converter and NOx sensor: Unfortunately none from available diagnostic programs don’t gives a clear view, in which mode does N43 and N53 performs on current moment AND which modes are allowed. For this reason we have to use several indirect evidences and parameters. First impression – information, in which mode the engine (N43/N53) operates you can find using INPA. More about basic operating principles of NOx catalytic converter you can read in N53 series engine after-sales training material or in any description of non-BMW engine, which performs in Stratified charge mode.
Here I will pay attention to observations from “real life”, which quite essentially differs from official newsletters. I get more and more questions regarding the topic of NOx catalytic converter. Some askers wont to change the exhaust, removing this catalytic converter; some are interested in the normal performance of the engine is possible without NOx catalytic converter. MSD80 records this message, if the mathematically counted parameter of sulfur “poisoning” is significantly higher than the norm, and the regeneration or catalytic converter is not performed/not possible. Causes for such situation could be. Error message 30E9 is specific, and it could be registered only in error message memory of MSD80 control unit for N43/N53 engines.
Only these engines have NOx system with NOx catalytic converter included in it. Why the error message 30E9 is registered? Engine: N43B20 Problems: increased fuel consumption, uneven running, increased CO/HC (the car is not able to pass TI). Few times per second MSD80 sends command or data request to NOx sensor. One hundred times per second NOx sensor “answers” to MSD80: execute required commands or sends measured data.
When fuel consumption grows, most probably, the rough run of engine has also started The NOx sensor is comparatively quite expensive spare part, it’s price is around 450. 500 EUR, but work-life: very limited. How to evaluate the performance of NOx sensor? Read more Also, F10/11 till LCI version is equipped with N53B30 series engines. Depending on power class, they are installed on 523i, 528i, and 530i.
