Electronic engine control unit - what is it?

The electronic engine control unit is an integral part of every modern car. This element is a kind of system that is responsible for the operation of the engine, transmission and other machine components, including electronic ones. In simple words, the control unit is the brain of the car, on the coordinated work of which the he alth of all constituent elements depends.

There is an opinion among motorists that this part is not subject to any repair and restoration, even in a service center. But it is still possible to repair the automatic transmission control unit, but only if the scale of the trouble is not critical. Of course, you will have to pay a lot of money for the repair of this part, but this is much less than the cost of a new unit.

Who should I contact for help?

Remarkably, many auto mechanics, when contacting them at service stations for such repairs, simply refuse to perform this work: they say, onlyreplacing a part with a new one. But here one should take into account one point that only non-professional workers say so. In a branded technical center, where many car owners are afraid to go in search of more economical options, such a service exists. However, if the severity of the breakdown does not allow the unit to be repaired even at a branded service station, of course, you need to change the part to a new one.

Should I rush to the store to buy?

Definitely not worth it. Now we'll tell you why. The fact is that it is not always the control unit that becomes the cause of the incorrect operation of the internal combustion engine and all electronic mechanisms. Therefore, before purchasing a new part, be sure to diagnose the car. So you can find out what is actually the source of the breakdowns. It is best to do diagnostics at the same branded service station. Please note that after completing this work, professional technicians can not only compile a list of faulty doers, but also explain to you what and where it came from.

I didn't send the car for diagnostics on time, I bought a new unit and only after installation I realized that the reason was not in it. What to do?

Yes, the situation is quite problematic. It took a lot of time and money to find and buy the block, but after replacing it, the motor and gearbox still work intermittently. In this case, the first step is to turn to the diagnosis. Yes, yes, to the one that was ignored when buying a new block. There, your car will be examined, a list of necessary forreplacement parts and will reveal the true source of breakdowns (but certainly not the pump control unit).

But what to do with the purchased electronic control unit? No matter how offensive it may seem, it can only be left as a souvenir (or until the moment when the old one breaks). The fact is that even under the law it is impossible to return this item back to the store. And the sellers themselves do not seek to accept the part purchased from them by the motorist, even through the court. Therefore, be careful and do not make hasty decisions.
