Volkswagen Jetta Engine

Volkswagen has produced the Jetta for seven generations, from 1980 to the present. The 2023 model is already up for grabs and is as perfect as ever.

Over the generations and years, Volkswagen has used several engine options on the Jetta. However, in this article, we will discuss the EA211 1.4 TSI.

VW Jetta 1.4 TSI Engine Overview

The 1.4 TSI is a 1.4-liter four-cylinder gas engine and a member of the EA211 series. The engine is designed to use on the Volkswagen MQB platform, on which the Jetta is based. At first glance, the new 1.4 TSI looks like a modified 1.4 TSI EA111. The two have a lot in common. They look the same, have similar displacement, and crank out the same amount of power. However, the 1.4 TSI EA211 is an entirely new powerhouse.

VW Jetta 1.4 TSI Features

Compared with its predecessor, the 1.4 TSI EA211 engine has more to offer in terms of performance and efficiency. The engine features a lightweight aluminum block with cast iron liners, a crankshaft and connecting rods made of die-forged steel, and a cylinder bore and stroke of 74.5mm and 80mm, respectively.

The 1.4 TSI engine features an aluminum alloy cylinder head with a dual overhead camshaft configuration with a water-cooled exhaust manifold. And with a timing belt driving the cams, the 1.4 TSI incorporates variable intake and exhaust timing. The hydraulic tappets and roller finger camshaft followers are designed to give the 1.4 TSI engine an automatic valve clearance adjustment and provide low friction.

The engine's turbocharger system features a water-cooled intercooler integrated into the intake manifold. The cooling system features two loops. A low-temperature loop flows via the turbocharger housing and the intercooler.

Additionally, the integrated exhaust manifold quickly attains its ideal operating temperature after igniting the engine. It also cools the hot gases from the exhaust in its full power mode, which as a result, increases the turbocharger's longevity. The engine also has a catalytic converter located beyond the turbocharger for a faster warming-up process.

Volkswagen uses direct fuel injection in the Jetta 1.4 TSI. The high-pressure fuel pump has a maximum injection pressure of 2900 psi. And with cylinders' five-hole injection nozzles with up to three distinct injections, the fuel injection system offers precise fuel delivery into the combustion chambers. The Volkswagen Jetta 1.4 TSI produces 147 horsepower at 5,000 rpm and 184 lb.-ft. of torque at 1,400 rpm.

Common Problems of the VW Jetta 1.4 TSI Engine

The Volkswagen Jetta 1.4 TSI engine comes in two versions, the EA111, introduced in 2005, and the more advanced EA211, launched in 2012. Both series are not excellent and haven't made the Volkswagen Jetta one of the most reliable sedans on the market. Though, the engine has bagged several awards, including the International Engine of the Year Award.

These stats may make you think that the 1.4 TSI is a perfect engine, but it is not entirely. Because, like any other mechanical machine, the 1.4 TSI has its fair share of problems. The EA211 does not have as many issues as the earlier EA111. It is a newer introduction with several upgrades that fixed problems experienced in the EA111 1.4 TSI engine series.

The following are some common problems of the Volkswagen Jetta 1.4 TSI engine.

• Oil Consumption Issues

While no problem is good, excessive oil consumption is an issue that you don't want to experience often with your vehicle. This is a problem most experienced with older 1.4 TSI engines, especially the versions introduced in 2005.

If you notice that your Jetta is drawing more oil than normal, this could be the problem. You should schedule an oil consumption diagnosis as soon as you can. If it goes on unattended for long, it could cause serious problems to the engine.

In older 1.4 TSI engines, Volkswagen didn't use the most reliable pistons and rings, resulting in the engine swallowing more oil than it needed. If you think you have an excessive oil consumption problem, one of the few precautions you should consider is taking an oil consumption test to ensure that your pistons are in perfect condition.

Other precautions include using the right oil as directed in the Volkswagen manual and feeding your 1.4 TSI with good-quality fuel. Some symptoms of excessive oil consumption include poor engine performance, increased oil deposits, poor fuel economy, and blue smoke from the exhaust.

• Tensioner Failure

The new 1.4 TSI, the EA211, does not use a timing chain. Instead, the engine uses a timing belt to drive several critical parts of the engine. This means that this series of the 1.4 TSI doesn't have the timing chain tensioner problems.

Unfortunately for the EA111 1.4 TSI, the engine suffers tensioner failure like many other Volkswagen engines. If the tensioner fails, it affects the engine's timing and could cause serious damage to the engine pistons.

If you are driving a VW Jetta powered by a 1.4 TSI from this series, the best cause of action is to replace it even before it fails. In most cases, once you replace the tensioner with a high-quality one, the problem may never occur.

Poor performance is one of the most common symptoms of a timing chain fault. Your engine may also produce rattling noises when at idle. Other signs include engine shuddering, loose timing chain, and metal shavings in the oil pan.

How do you deal with a faulty timing chain tensioner? There are two options to choose from. One is to replace the tensioner itself, and two is to replace the entire timing chain kit. We highly encourage drivers to choose option number two so that they don't have old components mixing up with new ones.

• Faulty Ignition Coil

Many engines with turbochargers are experiencing ignition coil failure nowadays, and the 1.4 TSI under your Jetta's hood is no exception. The ignition coil works with the spark plugs to aid in fuel combustion. When you turn the key, the ignition coil carries voltage from the battery and creates a spark with the plugs to ignite the fuel.

If one of these two isn't working correctly, your 1.4 TSI will experience a misfire. The ignition coil in your Volkswagen Jetta should last at least 100,000 miles.

If there's a problem with your ignition coil, the vehicle's computer system will throw in some engine misfire codes. The check engine light will also illuminate. Other symptoms of a faulty ignition coil are decreased acceleration, rough idling, or the engine won't start.

• Turbo Wastegate Rattling or Sticking

Turbo wastegate sticking is a common problem with the new 1.4 TSI engines. A wastegate in a turbo system is a valve that controls boost pressure. It regulates the turbine speed and ensures that it doesn't spin too fast to cause an indefinite rise in boost pressure.

There are two ways this valve can fail; it can remain stuck open or stuck closed. If it gets stuck open, the turbo will provide a lugging boost. On the other hand, if it remains stuck closed, it'll provide an excessive boost. None of these scenarios is good for the turbo. It can cause them to strain, resulting in more severe damage.

If the problem remains unattended, the turbos may blow and be expensive to fix. Fortunately, the wastegate is an easy problem to fix, but this only favors those who take action before the problem becomes critical.

Suppose your Volkswagen Jetta has a faulty turbo wastegate. In that case, you will experience a dramatic drop in fuel economy, poor performance, especially decreased acceleration, rattling noises from the turbo, and engine flutter. There are other symptoms, but these are the most common.

If you are certain that it's the turbo wastegate causing all the mayhem, you only have two options. You can either replace the valve or the entire turbo. This is not a simple DIY - you will need a professional VW mechanic to check and fix it.

VW Jetta 1.4 TSI Engine Reliability

If you are thinking about or already own a Volkswagen Jetta, don't question your decision because of these problems we just listed. Every engine has its good share of faults.

On the bright side, you only need to follow your mechanic's maintenance schedule religiously and use the right fuel and oil to drive your Jetta up to 160,000 miles and beyond. Of course, the new 2023 model doesn't offer the 1.4 TSI. It has the 1.5-liter turbochrged engine instead. But for a used sedan, the Jetta 1.4L TSI doesn't look too bad if it still has low mileage and no issues.
