8 Most Typical Jeep Wrangler EcoDiesel issues

  • Exhaust couplers leakage
  • EGR cooler malfunction
  • Oil cooler malfunction
  • The gear on the camshaft is slipping
  • Fuel with water in it
  • Turbo lag
  • Issues with the diesel particulate filter (DPF)
  • Issues with the oil separator

Each Jeep EcoDiesel issue will be examined in more detail in this post. I’ll also offer some advice on how to prevent or resolve them.

An additional frequent Jeep EcoDiesel issue is a leaky exhaust coupler. The couplers are in charge of joining the turbocharger and the manifold to the exhaust pipes. Exhaust gases may seep into the cabin if they leak. 

This can result in turbocharger failure, which is dangerous not just for the car’s occupants. The turbo may malfunction due to overheating from exhaust fumes.

On EcoDiesel, changing the turbo is neither simple nor inexpensive. It will cost you $2500 for the part and labor. Because of this, it’s critical to identify the issue quickly and change the couplers.

In most cases, the issue is caused by a buildup of carbon deposits. You can take them out in an emergency with a thorough cleaning, but replacing the couplers is normally preferable.

The EGR cooler must cool the exhaust gases before being recirculated into the engine. If it malfunctions, the engine may become overheated and sustain damage. Once an EGR cooler malfunctions, soot accumulation is typically the issue. This may occur if the car is rarely driven or only used for brief distances.

Therefore, going on long rides in your Jeeps might help you prevent this issue. This will aid in soot removal and maintain the EGR cooler’s proper operation.

Additionally, if the EGR cooler is already faulty, you can have it cleaned or replaced. Although this isn’t a cheap remedy, it’s significantly less expensive than replacing the engine or having a fire.

One of the most frequent Jeep EcoDiesel issues is oil cooler failure. The oil cooler is in charge of cooling the engine oil; if it malfunctions, the oil might overheat, harm the engine, or even catch fire. 

When oil isn’t replaced frequently enough or the wrong type of oil is used, the sludge builds up in the cooler, which is the major cause of oil cooler failure.

It’s crucial to closely monitor the engine oil level and replace it following the manufacturer’s instructions if you want to identify this issue early. Additionally, you have to utilize premium synthetic oil. Even though this project might cost several thousand dollars, replacing an engine is more expensive.

The camshaft gear operates the timing valve. The engine may run rough and might stall if it slides. The most common cause of this issue is oil buildup on the gearbox. This may occur if the lubricant is not changed often or if the wrong kind of lubricant is used.

It’s also important to note that EcoDiesel uses 9 gallons of 5W 40 lubricants. That equals $100 only for the oil. Additionally, you must utilize a high-quality cartridge-style filter, which costs $92. The price of a changing the oil now totals slightly over $200.

Therefore, while avoiding camshaft issues is not inexpensive, replacing them is significantly more costly. The cost of a replacement camshaft is around $2000 with labor costs.

The repairs will be paid for if you’re fortunate enough to keep your Jeep covered by warranty at the time of the incident. But the full cost will be your responsibility if it’s past the warranty period.

Not just the EcoDiesel, but all diesel engines have this issue frequently. This is so that water can enter the gas tank in a few different ways.

1. Moisture absorption

Condensation is the most typical method for water entering your fuel. If the gasoline tank isn’t maintained full, water condensation will occur. This is especially valid during the winter.

2. Improper fuel

At the refinery, the pump, or anywhere in between, water can contaminate the fuel. Although it doesn’t happen often, this issue does arise occasionally.

You should only get fuel from reliable dealers if you want to prevent this problem. Additionally, you have to maintain a full gasoline tank. As a result, condensation will be reduced and water intrusion into the tank will be less likely.

If you think the gasoline may include water, you should empty it out right away. Never attempt to operate the car. Water may corrode fuel injectors and result in other pricey issues.

Another typical Jeep EcoDiesel issue is this one. When additional power is required, the turbocharger is in charge of supplying it, but it might take a few seconds to spool up, which is annoying when attempting to pass a vehicle on the freeway or merging into traffic.

You may take a few actions to lessen turbo lag. You may first replace the turbocharger. Although it isn’t a cheap solution, this will solve the issue.

Adding an aftermarket exhaust is another option. The turbocharger will spin up more quickly as a result of this.

You can also take greater caution when driving. This calls for avoiding abrupt accelerations and pauses. These two things can potentially make the turbocharger lag and work more than necessary.

The EcoDiesel’s turbo is extremely efficient, which is its best quality. You won’t notice a substantial decrease in fuel economy when towing or transporting a big load because it doesn’t utilize much petrol.

Power is amazing once the turbo engages. Power for regular driving and even moderate hauling is more than plenty, thanks to the turbocharged engine.

Soot and other particles from the engine exhaust must be captured by the DPF. The DPF may clog due to the accumulation of these particles over time. The engine will lose power and enter “limp mode”.

The DPF must be cleaned or changed to solve the issue. Avoiding the problem from the beginning is crucial since fixing it might be expensive. The easiest method to achieve this is to replace the oil often and use high-quality gasoline.

Additionally, you want to steer clear of prolonged idling and sluggish driving. These may speed up the process of the DPF becoming clogged.

If your DPF becomes clogged, you have two options: utilize any DPF cleansing kit or have it professionally cleaned.

You may also give long stints of high-speed driving a try. This will assist in cleaning the DPF and “burning off” the particles. This approach isn’t always practicable and could even be harmful.

Oil and water must keep clear from the engine thanks to the oil separator. These fluids can potentially cause pricey issues if they enter the combustion chamber. In colder months, this issue is more prevalent since this oil is heavier and flows less smoothly when it’s cold, the separator clogs and breaks down.

You should frequently replace the oil and use high-quality synthetic oil to avoid this issue. This will lessen the possibility of blockages and keep the oil pouring down.

Additionally, you want to think about putting in an accessory oil separator. These are reasonably priced and will help you save significant money over time.

The main drawback is that not every brand is trustworthy. You could be fortunate and get one that functions well, or you may receive one that creates more issues than it resolves.

Is a Diesel Jeep Better Than Gas?

When it comes to choosing between a diesel Jeep and a gas Jeep, there are a few things you need to take into account. 

First of all, how will you be using your Jeep? If you’re planning on doing a lot of off-roading or heavy towing, then a diesel Jeep is the way to go.

Diesel engines have much more torque than gasoline engines, so they’ll be able to handle anything you throw at them. 

Plus, they’re more fuel efficient, so you’ll save money in the long run. However, if you don’t plan on doing any serious off-roading or towing, a gas Jeep will probably be fine.

It’s important to remember that diesel Jeeps are also much more expensive than their gasoline counterparts. So, if cost is an issue, then a gas Jeep is probably the better option.
