Go through the following slides to know about the reasons behind the fuel smell which is coming from the Volkswagen.

1. Reasons For Foul Smell Coming From
Your Volkswagen

2. Nobody would like a lingering
unpleasant smell in their Volkswagen
as it will make driving the car very
difficult.

3. Moreover, while driving your
Volkswagen if you experience a strong
smell of sulfur, then it indicates a
serious issue in your car.

4. Whenever something breaks within
Volkswagen's fuel or exhaust system,
it can inhibit this process and create
the smell.

5. Here are the reasons behind the foul
smell coming from your Volkswagen.

6. Damaged
catalytic
converter

7. The most likely reason behind the
pungent smell from your Volkswagen
is the catalytic converter which is a
part of the emission control system.

8. When the gasoline reaches the
catalytic converter, the role of the
converter is to transform the trace
amount of hydrogen sulfide into
odorless sulfur dioxide.

9. The catalytic converter is designed in
such a way to reduce harmful
emissions by converting exhaust
gases like hydrogen sulfide into
harmless gases.

10. However, a broken or jammed
catalytic converter cannot properly
process the sulfur gases and will
cause your car to have a pungent
smell.

11. Malfunctioning
fuel pressure
sensor

12. The role of the fuel pressure sensor in
your Volkswagen is to regulate the
use of the fuel in your car.

13. However, when the fuel pressure
regulator malfunctions, then it leads
to clogging of the catalytic converter
with too much oil.

14. The large quantity of oil prevents the
converter from processing all the
exhaust byproducts which exit the car
through the tailpipe and produce the
foul smell.

15. Moreover, an excessive amount of
byproducts can also build up within
the catalytic converter and cause it to
overheat which contributes to the
smell.

16. Old
transmission
fluid

17. If you have forgotten to flush your
transmission system, then the
transmission fluid may begin to leak
into other systems which leads to foul
smell.

18. However, it is very easy to deal with
this problem as you only need to
routinely change the transmission
fluid as suggested by your
Volkswagen's manufacturer.

19. Whenever you experience these foul
smell coming from your Volkswagen it
is important to inspect the cause of
these smell.

20. You need to immediately take your
Volkswagen to an automotive repair
shop to diagnose the cause of the
smell and fix the issue.
