Specialists of the Consumer Reports really like its roomy carbon, great engine power, and proper handling.
Kelly Blue Book has complemented the automobile’s fuel economy and powerful acceleration.
Its interior space seems larger than other cars previously produced by Volkswagen.
The comment of Edmunds focuses on the turbo engine equipped with modern and tight handling.
Although the exterior style of bodywork seems out-of-date, the fuel economy is a plus compared to the former vehicle models.
What Are The Volkswagen Jetta 2007 Problems?
You could face various 2007 Volkswagen Jetta problems, like some popping noise from the trunk and show no signs of engine activation after refueling.
Besides, decreased power or oil leakage are also common problems.
No Start After Refueling And Popping Noise From Trunk
Under many circumstances, your car doesn’t start or stall after getting gas, which is mainly attributed to the stuck EVAP purge control valve.
Due to engine stalling, the fuel vapor cannot push out of an intake manifold, placing more pressure on your vehicle’s related engines.
Other culprits behind the issue include a clogged fuel filter, a bad battery, a broken fuel pump, or other mechanical and electrical issues.
The failure of an EVAP purge control valve is also conducive to strange sounds from the trunk.
A worn control valve is unable to close and remain open all the time, preventing the fuel tank’s pressurization.
Hence, you might hear popping sounds inside your car, which become louder when you decrease the speed.
Reduced Power And Fuel Efficiency
The Jetta series of Volkswagen from 2006 to 2016 models are equipped with a direct injection engine.
Although this motor part is created to improve gasoline usage, carbon accumulation within its space is one of the primary contributors to the diminished fuel efficiency.
Over time, the engine’s interior surfaces are easily clogged up with dirt and debris due to the constant exposure to water droplets in the air.
If this problem prolongs, the airflow and gasoline delivery cannot happen as normal. The serious consequence is a loss of power and other engine issues.
Besides, the engine cannot burn the fuel completely and properly, resulting in fuel loss and reducing fuel economy.
Coolant And Oil Leakage
In most situations, the coolant leak stems from a blown head gasket.
This part is responsible for managing a wide range of temperatures and moderating the pressures between different engines.
That’s why when it is prone to damage, the engine oil and coolant get separated, allowing coolant to leak outside the engine and reducing its stable level.
Apart from that, it also poses a serious threat to other motors and causes them to fail.
A malfunctioning head gasket also induces the oil leakage into the coolant system’s combustion chamber.
If there are holes in the oil pressure channels, external oil leaks might occur.
Illuminated Check Engine Light And Hesitation Due To Malfunctioning High Pressure Fuel Pump
The 2007 Volkswagen Jetta automobile either runs on 2.0L turbo charge engines or 2.5L 4-cyl engines.
Without proper and regular maintenance, they often develop hesitation on the acceleration because of a bad fuel pump.
The main reason behind this issue is normally boiled down to a worn-out camshaft.
And when your vehicle detects something abnormal, the powertrain control module will send signals to the check engine light and illuminate it as a way of notifying drivers.
To avert this issue, you should inspect the camshaft every 10,000 and 15,000 miles. Or else, call a professional mechanic if you hear some strange sounds.
Wrong Antifreeze And Heater Core Damage
After a period of usage, your Volkswagen Jetta 2007’s heater core will wear out, and it is easily susceptible to premature wear if you don’t examine and clean it regularly.
Yet, the improper maintenance of the coolant in your car or the wrong types of antifreeze are underlying factors behind the failure of a heater core.
In this case, you are advised to change it immediately with a suitable one.
Oil Leaks From The Camshaft Chain Tensioner And Valve Cover Gasket
Besides the head gasket, the camshaft chain tensioner and valve cover gasket are also susceptible to oil leaks.
This problem derives from a rusted O-ring that no longer tightens the tensioner and gasket.
Yet, this issue is not too worrying, as it can be addressed if you notice the problem soon and seal the leakage hole so no drips fall on the garage floor.
Odor From HVAC Vents
Sometimes, you must ensure bad smells emanating from HVAC vents. For the most part, the reason lies in your dirty lifestyle, as you don’t usually clean the air conditioner and its HVAC vents.
So mildew stands a good chance of thriving in this contaminated environment.
Other causes include stagnant water collected in the AC or the odor of rotting garbage near your car that flows into an air duct while you let your vehicle open.
The Failure Of Power Windows And Manually Operated Window Cranks
Power windows could be damaged after being put under constant stress.
This usually happens in winter when your windows must endure the great divergence between outside temperatures and inside your automobile.
Another cause is the wrong regulator that hinders the power window’s movement. No matter how many times you press the button, it doesn’t move.
And if you are unclear about this cause and continue to push the window, some cracks on its surface may pop up.
