2009 Volkswagen Eos Problems
RepairPal has identified the most common problems with the 2009 Volkswagen Eos as reported by actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.Refine by vehicle
Condensation may develop in the heater case which can cause a musty odor from the heating, ventilation and AC (HVAC) system. Our technicians tell us the drain system should be checked for debris. In addition, a cleaner is available for the heater case.
The Volkswagen Eos uses the FSI and TSI direct injection engines. These engines are subject to carbon buildup in the intake system which can cause power loss, OBD codes and a check engine light, and a rough idle. In normal engines, the engine is cleaned by the gasoline flowing through the injectors and into the intake system, however, since the Eos uses direct injection, gasoline does not flow through common carbon buildup areas.
The solution is to remove the intake manifold and professionally clean the intake manifold, intake ports on the cylinder head, and the intake valves. This may need to be done in as few as 20,000 miles.
The 2006-2008 Volkswagen Eos with the 2.0L Turbo FSI engine looses power if the turbocharging system has a leak. The most common turbo boost leak is a torn rubber diaphragm on the diverter valve, which is intended to open only if pressure gets too high. Common symptoms are increased turbo noise when letting off of the gas pedal, and power loss.
If there is a turbocharging system leak, the system will need to be inspected, and the defective seals and/or valve will require replacement.
The flywheel for the 2007-2009 Volkswagen Eos with the 2.0L Turbo engine is a non-conventional "Dual Mass" flywheel. It is known to make light rattling noise when the engine is cold, and should subside once the engine temperature raises. If the rattle doesn't go away when the engine warms, the flywheel may have failed.
If the dual mass flywheel has failed, the only solution is to replace the flywheel.
2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. To help prevent this issue from occurring, the cam follower should be inspected every 10,000 - 15,000 miles. The camshaft lobe pushes on the follower to operate the high pressure fuel pump.
To correct this issue one or all of the following will need replacement: the camshaft, high-pressure fuel pump, and/or the cam follower.
An issue may develop where a window will not roll up after a short pulse down. Our technicians tell us this is a normal condition. Cycling the power door lock followed by the key switch will reset the programmer and restore proper window operation.
A brake pulsation may develop due to improper torque of the wheel lug nuts. Our technicians tell us the lug nuts should be hand torqued to the proper specification to help avoid this condition.
