Fault diagnosis: the BMW 760Li cold get started, jitter, and is particularly accompaniedX431 Diagun
by an engine fault gentle flashes, CID prompt transmission failure, if the re-start after a flameout every little thing is standard, ordinary hot motor vehicle.
The connection the ISID done diagnostic and found that there the multicylinder flame cylinder 2 injection gadget is closed, and the cylinder 6 injection product is closed fault code. Evaluation screening software to auto diagnostic software
check the high-pressure cold start out, when there'll be some fluctuations, although not terrific; examining the injector harness connection is typical; high-pressure element of the non-leakage, ignition coil and spark plug standard. This vehicle to interchange the cylinder 2 cylinder the 6 injector too as high-pressure pump, and cleansing the inlet throttle, spark plug following the ingestion valve, take away the tuning values ??to match the injector, set up retest automobile, ordinary check out The information were also usual. Being parked for just a night, the following morning located the vehicle while in the chilly when there exists jitter and accompanied from the lights of engine failure, just a little bit superior jitter, fault codes Periods cylinder 1, cylinder 4 cylinder 5 flameout.
Carefully imagined for a moment then, this BMW V12 engine, a single-cylinder column 1 fault, 2 standard directions cylinder column. A careful assessment of column two cylinder frequent low-pressure fuel system, the cylinder column 2 ordinary for the low-pressure gasoline procedure along with other devices are thoroughly shared; noted multicylinder Misfiring point you will find a different cylinder to cylinder column 1 and didn't discover any regulation, every cylinder ignition must be no challenge, cylinder pressure, fuel injection and ignition coil wire, plug, and VANOS procedure is standard. Envision if a cylinder ignition coil or weakened spark plug, the cylinder would certainly are noted fault code that auto diagnostic tool
also remaining the gas supply technique. Before assessment in the low-pressure gasoline system is regular, then only the high-pressure gas method.
High pressure gasoline pumps as well as quantity of integration inside the high-pressure pump handle valve replaced ahead of the car,auto code reader
visible inspection from the high-pressure line and fuel rail connection at no traces of fuel leaks, check the higher tension sensor, examine the high pressure value credible. Merged with all the chilly get started challenges, along with the fault gentle blinking phenomenon, we conclude that there is a leak high-pressure method. The motor employs open outwards piezoelectric injectors, the gas while in the soil for long-term, this injector a lot easier flameout just after injector Mifengbuyan led out to open up the nozzle needle and valve Block exudation phenomenon, that is definitely, we often state that the oil spill. For a a lot more extensive, precise diagnosis, we have adopted essentially the most primitive auto scanner
method to check. All injectors and higher pressure oil rail taken off, put in in accordance using the get of your injectors and higher force gas rail, injector head and then carefully wipe the convert at an angle, which is hooked up to each injector mat paper.
