View The Full Version : problem error 4293 bmw x3
good day guys, I would like to list a problem of this machine on behalf of a friend practically the car when it has the outside temperature is below 7? degrees the car starts and then turns off and does this continuously bringing in diagnosing the error 4293 and 4222 of the spark plugs, clear the ecu, glow plugs replaced and also the spark plugs in a bmw then they also did the alignment ews but nothing now they say that it only takes the engine control unit, the defect depends on you, I repeat, if the temperature ? the top 10?degrees the car starts and goes well the only thing the error in diagnosis, and only the spark 4222
Hello 4293, error of colour' internal control.
Checking the condition of the injectors, the return and flow.
Maybe, keep in monitored parameters, especially when the defect and see if you have one or more injector that is leaking.
then ? a problem with the injectors, and the car has 220000km then the error of the glow plugs not ? veritevole I could understand why? the problem is the injectors or the return thanks
Hello I've a problem with the 4293, my problem was an injector that was leaking in the event you have indicated.
Attention! I'm not saying that the problem is the injectors, but only make a check before replacing parts unnecessarily.
Regarding the spark plugs, I recommend you to do a check with your multimeter in ohms.
I hope that help
I understand costa thank you so far? check the injectors even why? the f? only a cold
It is very likely the injector that does not hold in the "return" smontali, and have them check you'll see that you find one that loses... gi? happened to me...? also check that when you defect in the priming feed pump functions..me ? a case successfully with the same problem and it was the rel?...
I wanted to update to the help given then I did redo the injectors to the friend even why? the km cerano the problem and less pronounced say that it takes less points to stay in motion, error, and always 4293 and 4222 now I wanted to check the pump in the tank, the filter, and if you give me a hand ? the rel? the pump then the returns have all been changed and controlled so they are not ustruiti
Hello duke, the tests that you want to do are right, also the control that you have specified the links silven is correct, but before changing parts, perhaps unnecessarily! you should do the audit, the correct check that you have specified the links silven you should have the confirmation and connect a pressure gauge in the low-pressure and keep monitored the power, then see if indeed the problem is the low pressure. Now I do not have the precise data of the car, but if I remember correctly, the relay of the pump you should find in the passenger compartment behind the glove compartment. For the fuel filter if you have the smallest doubt, change it! it is always welcome.
Of course, control of contamination diesel should do it.
I'm at the point, you should also check with a diagnosis attached to it when it the problem on the parameters what happens... check if when you turn off there is no voltage to the injectors, why? in that case it's not ? a problem of diesel also checks that there is a problem with the bulb for the oil pressure, those cars if the ecu gets that not c'? oil pressure (for various reasons... whether mechanical or electronic) in addition to the priming feed pump.
I instead of starting from the injectors control the temperature of diesel fuel and temperature sensor diesel I would if everything is ok then procederei to the injectors would be attributed also the anomaly to the glow plugs and then as we all know the density of the diesel fuel changes depending on the temperature and, therefore, impact on the injection.
colleagues, I wanted a little update when yesterday evening, I put myself, with the diagnosis then resets the error 4293 and the car in the cold part is a for about ten seconds and then goes off and then returns to the same error always with the glow plugs, then the error 4222 glow plugs ? always present then the permanent, then, is not reset while the other and then stops,then for the little that is in motion, the values that bust are the temperature of the probe to the depimetro the temperature of the water temperature, fuel type, temperature diesel 256? or water temperature 167? then I start to think of pi? to an electrical problem right.
Hello, no, no! I think that you are entered in diagnosis with a different protocol. the dtc you described have nothing to do with the anomalies that you have posted. ( tries to change the protocol or even make a diagnosis with other diagnostic ).
If you would have all these problems, the dtc would be other and and as a consequence also other problems on the engine.
I think it's a problem on the second cylinder. ( 4222 problem communication of 2? cylinder )
As I said the problem could be or the injector ( also checks if it is encoded ) or glow plugs ( have you checked the resistance of the glow plugs ohms with a multimeter ? ) or the command glow plug.
To the maximum if you do not have the possibility of instrumentation to perform these controls, invert before the glow plugs and see if the dtc moves.
Ps: a piece of advice that I would give you if you allow me, and do not continue to change anything until you have had confirmation of the replacement indicted otherwise have lost money.
The beautiful thing it is to find parts failure and then replace, but to do this you should carry out the checks indicated by me and colleagues.
Waiting for the opinion of other colleagues, maybe when you make these checks in the mail verdict that we rate them together.
I'm sorry, but I forgot to ask you if when you put in motion the car is smoking and if it does, have you noticed the color of the smoke?
of course I wanted to update and close the split at the end after the time the problem solved, and thanks to the help given to me here thank you also to the coast to finish in spite of the injectors had been replaced and the injector of the second cylinder I got it again at my own expense and it was just him, then the problem of the glow plugs was due to the command of the glow plugs so perfect machine, and cold start adjust thanks!

Great! I'm glad that you have solved. A dear greeting :)

You mean the ecu plugs?
