Adjustment of pump injectors - what does it look like and how much does it cost?

A common problem that occurs in older and popular car models is improper adjustment of the unit injectors. You will notice very quickly that something is wrong with them, because there are a lot of alarming symptoms. You should definitely visit the mechanic. So how much does an injector adjustment cost? We answer this question (and many others) in our article, from which you will learn why the adjustment of this element of the car is so important for comfortable driving.

Incorrectly adjusted pump injectors - symptoms. Recognize them quickly!

If you know your car well, you will quickly notice that something is wrong:

• your car will have trouble generating high revs;
• it will be difficult for you to start the car, both on a cold and on a hot engine. 
• there may also be smoke that should really bother you and make you go to the mechanic immediately. 

The car will jerk, accelerate and decelerate much more abruptly and less predictably. Therefore, if you see this type of problem, it may be caused by misadjusted unit injectors.

Symptoms of damaged pump injectors. Urgently to the mechanic!

If you notice a problem with the unit injectors, contact your mechanic immediately. Does the car stall at idle? Don't ignore these symptoms. Due to the quick response, it may turn out that only the adjustment of the unit injectors is required, and not the replacement of the entire system. Thus, you can save on repairs, which will also be much faster and more efficient. However, sometimes they may need to be regenerated. If the breakdown is really serious, then it makes no sense to take risks and it is better to replace it. If you do not, you may put yourself and others at risk.

How to check the injector pump? This is what professionals do

You should not drive with damage and independently check such complex elements as high-pressure fuel pumps. It is best to entrust this to a professional who, after connecting the car to the computer, should see all the possible errors that occur in your car. For example, in an Audi A4, you should check channels 13 and 18, as well as 24. However, if you do not have specialized equipment and relevant knowledge, you should not diagnose the car yourself. In this way, you can only worsen his condition and lead to dangerous situations. 

Proper service is important

Therefore, before adjusting the unit injectors, it is necessary to contact professionals. Remember to choose only trusted sites. Ideally, they should be authorized by your vehicle manufacturer and have state-of-the-art equipment to allow quick diagnosis.

Adjustment of pump injectors. How much could it cost?

How much you have to pay for adjusting the unit injectors depends on the workshop that will take on the task. However, usually an adjustment will cost around 200-30 euros. This is not a particularly large amount, so do not delay if something bad happens to your car. You will most likely pay up to 10 euros just for cleaning the unit injectors, but do not forget that replacement repairs can cost much more. A lot depends on what brand your car is. Some companies have very expensive spare parts, which adds to the overall cost.

Adjustment of pump injectors. What should be checked?

In the service, they must not only adjust the pump injectors themselves, but also check them with a suitable meter. All components that can be a source of failure must be tested on test benches. An appropriate protocol must be written for this test. If your mechanic does this kind of thing, find another dealer. Only such a check of the unit injectors will give you confidence that they are safe to use and that your car will not refuse you obedience on the road. 

It is also worth checking other important parts of the car in the workshop to avoid unpleasant surprises. Just adjusting the unit injectors should significantly improve driving comfort and eliminate existing problems with the car. Remember, don't underestimate the malfunction symptoms we indicate, because road safety and the assurance that everything is in order with your car is priceless.
