Hi there. Check the engine for any fuel and oil leaks. There could be a split fuel line or the o-rings on the injectors could be split causing the fuel to slightly puddle up under the injector surface mounting area. Also look for and signs of oil leaking, which would be dripping onto the exhaust pipe and burning off. Most of the time, oil will drip out of the valve cover gasket and leak onto the exhaust system. Check the (PCV) positive crankcase ventilation valve and make sure that its functioning correctly. When operating the air conditioner or heater on your vehicle, the air coming in could be coming from the ambient air from outside sucking in all of the smells from outside. If there is no fuel or oil leaks, then check the cabin air filter as it could be clogged up with hair, dirt, and debris from outside. This can make a burning smell or a foul odor as the fan blows against it. Replace the cabin air filter if its dirty and plugged up. If you need further assistance with your vents blowing strong smells into the cabin area, then seek out a professional, such as one from Your Mechanic, to help you.

This may be caused by insufficient sealing at the drive belt auto tensioner damper when the auto tensioner fully operates under both high ambient temperature and high load conditions. To eliminate this concern, the shape of the drive belt auto tensioner damper has been changed.
One of the routine maintenance items that you should perform on your Jetta is the inspection and if needed, replacement of your serpentine belt. The serpentine belt is driven off of the crankshaft and drives accessories on the engine — power steering pump, alternator, and air conditioning compressor.
A serpentine belt is a relatively long, flat, multi-ribbed belt that is driven by the engine`s crankshaft pulley. The belt drives many, and often all, of the engine accessories such as the alternator, air conditioning compressor, power steering pump, water pump, and air pump.
The drive belt/s on your Volkswagen uses the engine revs to power the accessories in or on the engine of your vehicle. These may include your power steering, water pump air conditioning compressor and alternator. Most Volkswagen`s have 1 or 2 drive belts and in some instances, it may be called a serpentine belt.
As suggested in its name, a tensioner ensures the various belts—mainly the timing and serpentine belts—remain tight with the proper tension. The hydraulic oil that maintains this tension can seep out of the tensioner. When it does the associated engine belts become loose. A car that leaks oil is not an uncommon sight.
The timing chain cover gasket and timing chain tensioner may fail, causing an oil leak or excessive noise.
A serpentine is a wider, thicker, updated version of its predecessor, the V-belt. You`re more likely to find a V-belt in an older model, while newer cars have serpentine belts. , air conditioning, alternator, and other systems.
A V-belt is a drive belt that runs off a crank and pulley system. It typically moves between one or two engine systems, and many older vehicles require several V-belts to power the different systems in the engine. V-belts are less common today, for a few reasons.
Summary: The Major Difference Between Flat Belt Drive and V-Belt Drive is that the Flat belt has rectangular cross-section where width is larger than thickness. V-belt has trapezoidal cross-section where larger side width is closely the same with thickness.
V-belts are belts with a trapezoidal cross-section. Like other types of belts, they are used to transmit power or torque from the driving component to the driven component.
If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started. It is also possible for the tensioner pulley or bearing to wear out, in which case the vehicle will produce a grinding noise from the pulley.
The belt squeals because there is improper tension in the belt drive system. This is usually caused by a worn automatic tensioner, but other causes can include a contaminated belt (oil, belt dressing, etc.) or a belt that is too long or worn out.

Soap smell coming out of car after cabin change. Changed filter the the smell is still coming. What to do about this strong smell?
ANSWER : Hi There,
As you know, your car has a cabin filter that serves to filter the air that is introduced to the cabin inside the vehicle. The best way to remove your cars interior ac odor is to use a cleaner that uses enzymes. Enzymes in cleaners kill odors at the source and completely kill the smelly substance material and therefore stopping the a bad smell. To get rid of the smell, try the following: First turn on the ac to full, make sure the “recirculate” button is not on, spray a large amount of cleaner with odor killing enzymes into the EXTERIOR air intakes that are located just below the windshield wipers, let the car run for about 10 minutes with the ac on, after 10 minutes turn off ac and spray the cleaner into the ac vents on the INSIDE of your car. After doing all this, let the car sit for 20 minutes turned off and windows rolled up. Then repeat if the smell is still in the car. By doing this you are killing the bacteria or mold in the car ac vent ducts and also the evaporator mold that may be present.

Sour, stale smell coming from air vents
ANSWER : This is most likely a cabin filter that needs to be changed. Your car is equipped with an air filtration system that works similarly to your engine’s air filter in that it filters the outside air as it flows into the cabin of the car when you have the vents open. Over time this filter will get dirty just as your engine air filter does and, in some cases as you describe, it will emit an odor or smell that is filtered into the cabin when you turn on the vent air.
I would recommend having an expert mechanic, such as one from YourMechanic, come to your location to replace the cabin air filter for you.
hey i had a belt break while traveling on my 2004 honda pilot. It is the small belt and not the serpentine belt. The mechanic t
ANSWER : Hello. The smaller belt is known as your timing belt, and it works inside the engine to keep mechanical components aligned with each other during the compression cycle. The serpentine belt, which is the big belt, drives the alternator, water pump, AC compressor, and a couple of other components. If the small belt broke it is likely the timing belt. This will cause the car to stall, lights to illuminate, and can even cause serious damage to the engine. Typically replacing a timing belt is a lot more complicated and expensive than replacing a serpentine belt. You may want to receive a second opinion on the car before you go ahead with repairs.
High pitched whine noise is coming from behind or below glove box area. The noise occurs at low rpm at any speed, especially while turning left.
ANSWER : Hi there. The sound that you are hearing is probably from the blower motor to the heater / air conditioning evaporator. Remove the fuse to the blower motor and see if the sound stops. If the sound stops, then the motor or the squirrel cage is bent and rubbing. If the sound is still there when you remove the fuse, then it could be the alternator or power steering pump transmitting the sound through the cabin area. If you need further assistance with locating the source to the high pitch sound near your glove box, then seek out a professional, such as one from Your Mechanic, to help you.
Oil pressure light and strange noise when I accelerate past 2500 RPM
ANSWER : Anytime your oil pressure light comes on while driving, you should stop driving immediately and have your car checked out as soon as possible. The oil pressure warning light indicates that you have low oil pressure, which can cause severe damage to the engine. The noise you are hearing is likely due to the low oil pressure, and should be addressed as soon as possible. Contact a qualified technician, such as the ones available from YourMechanic, who can take care of diagnosing your oil pressure issue.
Smoke is coming from steering wheel column and there is a burning smell, loud noise from engine.
ANSWER : This sounds like there are two different problems, but the "something’s burning" problem is critical. There is obviously an electrical short somewhere inside the steering column that has already done damage, and could lead to a sudden shutoff in traffic, a fire, or worse. You should have this problem examined before driving further. I would recommend having a YourMechanic certified mechanic perform an Electric Problems Inspection immediately to diagnose this issue, provide an accurate assessment of damage, and estimate the cost of repairs. A YourMechanic professional can also perform an Engine is Shaking, Pulsating or Vibrating Inspection after checking out your electrical problem.
Detecting strong gas smell.
ANSWER : The EVAP system is used to prevent fuel vapors from escaping into the atmosphere. The powertrain control module (PCM) monitors this system to ensure it is completely sealed. If a leak is detected, the PCM will illuminate the check engine light. From what you describe, it sounds like you may have a leak somewhere around your fuel filler neck. However, the EVAP system is complex. Only inspection by a trained mechanic, like one from YourMechanic, will give a definitive answer.
