Signs Of Volvo ECU Problems

The ECU or your vehicle’s Engine Control Unit, is a key component of Volvo’s onboard computer. It regulates the numerous systems, as well as subsystems in the engine of your car. Moreover, it is responsible for keeping major components in check.

There are some signs of a faulty ECU to keep an eye out for, so you can prevent this issue from getting worse. Here they are:

1. Check engine light is illuminated

When your check engine light stays on constantly and does not go off, it is possible that your vehicle’s engine control unit or ECU has a problem. However, there are also some other reasons why your check engine light may be activated and turned on. Yet, with an ECU problem, it is more likely to occur. 

Hence, if you see this is a prevailing issue, it is best to get your vehicle checked to diagnose the problem correctly. You will need to get your car serviced to make sure the ECU is not the problem – and if it is, to get it fixed sooner rather than later.

2. Starting issues

It is also possible that your Volvo has problems with starting for no clear reason. If this is the case with your vehicle, then it may be a fault with the ECU. You can also inspect other components such as the starter and battery and other key electrical parts. But if your vehicle still fails to start, then you may need to have the ECU replaced or repaired to solve this starting problem.

In addition to the symptoms mentioned above, there are a few other reasons why your ECU may be malfunctioning. For instance, an unexplained issue with fuel efficiency, as well as poor performance can be linked with ECU problems.

When your ECU is damaged, you may also encounter issues when you shift gears. This is typical among automatic transmission vehicles with a faulty ECU. Sudden stopping or jerking can also arise, which is similar to a transmission issue. But if you have sufficient transmission fluid levels, and yet you still come across these problems, then you will need to have your ECU checked.

What Are Your Options

If you are certain that the ECU is indeed damaged, or it is likely to go bad at any point, then you need to make it a priority to have your vehicle checked at a repair shop. You should opt for a mechanic that has the latest technology for diagnosing the onboard computer of your vehicle to make sure proper diagnosis is done.

There are many repair shops out there, however these are not created equal. This is why it is always a great idea to go to one that is an expert in this particular problem. In fact, only authorized dealerships will have proper equipment that can thoroughly diagnose the issue and provide you with the most definitive readings and favorable results worth your time and money.

As for the cost of repairs, it can be quite pricey. To begin with, the part costs about $1000 to as much as $3000. This also depends on the model and make of your Volvo car. Thankfully, the ECU can be reprogrammed or repaired. This is why it may be possible for you to not have to replace the entire unit, which also saves you some money.

As for the inspection and testing at local repair shops, this type of service can set you back around $150 to as much as $300. If you only need to have the ECU reprogrammed or repaired, the running cost is about $300 or upwards $700, and it all depends on your vehicle’s model and make.

Labor costs if you need to have the part replaced can be about $500 to as much as $600, depending on your location.
