Known Problems

The Volkswagen Tiguan uses the TSI direct injection engine. This engine is 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 Tiguan uses direct injection, gasoline does not flow through common carbon buildup areas. 

Possible trouble codes include: P0300P0301P0302P0303P0304.

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. 

There have been several reported instances of carbon build-up in Volkswagen direct-injection motors. Use of premium fuel is recommended, along with allowing the vehicle to fully warm up during drives.

Severe carbon build-up can cause several issues such as rough cold idle, hard starts, decreased acceleration, misfires, black clouds under hard acceleration, and the illumination of the check engine light.

Repair of this condition once severe requires the physical cleaning of the intake manifold and intake ports on the head. Due to its time consuming nature, this repair can be expensive.

Because of issues with the glow plugs and/or the glow plug wiring harness from the control relay, the Check Engine Light may illuminate. Our technicians tell us there is a service bulletin, not a recall from Volkswagen regarding replacement of the glow plugs on 2004-2005 model years only.

Due to an ignition component and/or engine coolant temperature sensor failure, the Check Engine Light may illuminate. Replacement of the failed component will be necessary to correct this concern.

The 2006-2017 Volkswagen Passat uses 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 Passat uses direct injection, gasoline does not flow through common carbon buildup areas. 

Possible trouble codes include: P0300P0301P0302P0303P0304, P0305, P0306.

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 driver door wiring loom cracks and degrades with time due to weathering and frequent opening and closing of the door. This problem affects the normal operation of all electronic components of the door including, but not limited to:

  • Electric Windows
  • Electric Door Locks
  • Trunk Release
  • Fuel Filler Door Release
  • Speakers
  • Interior Lights Stay On at All Times
  • Keyless Locks
  • Power Side Mirrors
  • Alarm
  • The correction for this issue is to replace the driver side door wiring harness. For security purposes, the doors can be locked with the key. The interior lights should be shut of manually, and through the multi function display in the gauge cluster to prevent battery drain.

    Electrical issues that are difficult to diagnose—and sometimes intermittent—are typically due to ground wiring issues. The most troublesome ground locations are under the battery or at the engine.

    Reverse gear failures and noise in the manual transmission models are common.

    The Check Engine Light may illuminate due to a faulty oxygen sensor and/or coolant temperature sensor. Proper diagnoses will be required to confirm the fault.

    An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light. Vehicles equipped with spark plug wires may also develop a misfire caused by a failed spark plug wire.

    Shifting issues due to internal problems in high mileage automatic transmissions can be difficult to resolve without transmission replacement.

    The 2006-2016 GTI uses 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 GTI uses direct injection, gasoline does not flow through common carbon buildup areas. 

    Possible trouble codes include: P0300P0301P0302P0303P0304.

    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. 

    Oil and carbon tend to build up, creating restrictions in the intake manifold. Symptoms will be loss of power (sometimes severe) and poor fuel economy.
