When To Replace the Coolant Temperature Sensor in Your VW

Volkswagen Service Center

What is the coolant temperature sensor?

The coolant temperature sensor is also referred to as the ECT. This sensor measures the temperature of your VW’s engine. The information that it gathers affects fuel delivery, ignition timing, and engine performance.

The ECT is usually attached to the engine block or cylinder head. It is near the hottest flow of coolant. In some instances, there may be more than one coolant temperature sensor installed. They are placed in different locations.

The sensor is partially submerged in the coolant. It sends the data that it collects to the engine’s computer. This allows your car to know if it is running too hot or too cold.

Symptoms of Coolant Temperature Sensor Failure

A bad engine coolant temperature sensor can produce a lot of symptoms. When the sensor fails, your engine will no longer be as efficient. Below is a list of the most common symptoms that you may experience:

Poor Gas Mileage

When you first start your car, the computer uses information that it receives from the coolant temperature sensor. This can lead to a rich-running engine. Once the engine heats up, the oxygen sensors gather the information.

Engine is Running Poorly

When the sensor is bad, your engine will no longer run efficiently. You may even experience backfires.

An Overheating Engine

The cooling fans will not be turned on if the computer does receive the correct reading. This will cause your engine to overheat. Never run your VW with an overheating engine. When it overheats, immediately pull off the road and turn off the engine. Continuing to drive an overheating vehicle will lead to engine damage and possible engine failure.

Engine Stalls

An engine takes a while to heat up and needs more fuel to idle smoothly. If the engine’s computer doesn’t know when to add extra gas, the engine can stall.

Increased Emissions

If your engine thinks that it is cold, it will add extra fuel. This causes the engine to run rich leading to higher emissions.

Black Smoke

If your engine is getting too much fuel, it will not be burned in the combustion chamber. Instead, it will be burned in the exhaust. This leads to black smoke coming out of the tailpipe.

Check Engine Light is On

Anytime your vehicle’s computer becomes aware of a problem, it will try to inform you. This usually happens by triggering the check engine light. Many issues can turn the light on. Once your light illuminates, take your VW to a trusted mechanic They will be able to run a diagnostic scan to determine the exact issue.

Can you still drive your vehicle?

If your coolant temperature sensor is failing or has failed, do not continue driving your vehicle. You should get it fixed right away. A faulty sensor can lead to overheating. This will cause damage to your engine as well as other components, which will be very expensive to fix.

How often does the sensor need replaced?

Coolant temperature sensor failure is common in Volkswagens. Properly maintaining the engine’s cooling system will help prolong the life of the component. It is recommended that the sensor is replaced at 100,000 miles. Not staying current with your maintenance schedule can cause it to fail sooner.

Our technicians will determine if the issue is due to coolant temperature sensor failure.

Volkswagen Ignition Coil Repair Service

Volkswagen is a classic brand known for producing cars with great fuel economy. The Volkswagen Jetta sedan offers smooth rides, with a sizeable trunk space. However, this car comes with its fair share of technical problems, one of which is the Volkswagen ignition coil failure.

The essence of an ignition coil is to ignite the fuel, and thus start up the vehicle via voltage transmission. It is essentially a transformer that converts the battery’s low power supply to a high voltage needed to jump-start the spark plug.

How To Detect Ignition Coil Failure

Potential signs that you have a defective ignition coil may include one or more of the following: startup problems: loud engine cranks, backfires, engine hesitation, stalling, decreased fuel economy and increased gas emissions. A more hazardous sign is an engine fire. Paying no heed to these indicators puts you in a vulnerable position and will put your car at risk for more damage.

Causes Of Volkswagen Ignition Coil Failure

The main reason why ignition coils fail prematurely is because of a worn-out spark plug ignition cable. An open coil wire, voltage overload, damaged or bad plug wires and spark plugs, heat and vibration are some other factors that could seriously damage your ignition coil.

How Do We Repair a Faulty Volkswagen Ignition

When you bring your vehicle to us suspecting a defunct ignition coil, we first carry out a preliminary investigation of the causative factor. Our diagnosis involves checking for misfires and checking to see if this indeed is caused by the spark plug, as misfires can be caused by a host of other things. Next, we remove the spark plug and inspect it, checking for dirt buildup and oil deposits. Our evaluation would not be complete without a voltage test on the ignition coil.

Usually, the results from this evaluation will warrant a replacement of the ignition coil. This problem is a relatively common technical issue and should not be allowed to persist so you don’t wear out your engine.

If your Volkswagen is having any mechanical or ignition coil issues, bring it to any of our Locations for an inspection. To Experience the Eurofed Difference, schedule an Appointment and a service manager will respond as soon as possible.

Top 5 Problems Affecting Volkswagen Jetta Models

Despite the Volkswagen emissions scandal in 2015, sales have begun to pick up in 2018. And by far the Volkswagen Jetta remains the most sought-after VW model. The company has completely shifted focus on a “customer-first” strategy. Furthermore, there new 6-year / 72,000-mile bumper-to-bumper warranty helped boost sales.

Even though Volkswagen is German made, it still comes with its issues that the buyer should be aware of. According to RepairPal, these are the top 5 problems that occur with the Volkswagen Jetta:

1. Automatic Transmission Shifting Issues

The number one problem affecting the Volkswagen Jetta is a shifting issue with the automatic transmission. Fortunately, this is only affecting vehicles with high mileage. However, this is an expensive fix and might need a transmission replacement.

This issue is affecting most models before 2013 with an average mileage of 123,000 miles. If you are experiencing shifting issues with VW Jetta, schedule a service appointment today.

2. Engine Misfire

When an engine misfire happens, the dreaded Check Engine light illuminates. Either a failed ignition coil or spark plug causes the misfire. If your VW has spark plug wires, a failure in them could also cause an engine misfire. To fix this issue, you will need to replace the ignition coil, spark plug or spark plug wires.

This issue is affecting 2012, 2013, and 2014 models with an average mileage of 112,000 miles and multiple engine types. If you have a Check Engine light because of engine misfires, make sure to schedule your appointment.

3. Power Window May Fail

Power windows are an amazing modern luxury in cars, but they tend to fail. In the VW Jetta’s case, this is simply due to a failed window regulator. The regulator will need to be replaced.

This issue is affecting 2010, 2014, and 2016 models with an average mileage of 90,000 miles. If you are having power window issues with your VW Jetta, schedule your service appointment today.

4. General Electrical Issues

There are general electrical issues reported with VW Jettas. However, they have been very difficult to diagnose. The problem has been reported to be a ground wiring issue, mostly found under the battery. Grounding is important to an electrical system and must be checked in order not to have intermittent problems

This issue is affecting many models, including 2012, 2013, and 2014 with an average mileage of 150,000 miles. If you are having electrical issues with your Volkswagen Jetta, schedule your appointment today.

5. Odor from HVAC Vents
