The Audi TT Quattro is a work of art in every way. Its AWD capability is its biggest selling point, by far, and has attracted both new and veteran car enthusiasts. People also attest to the power of the TT, as it navigates curves and sharp turns with relative ease. People never felt out of place with this roadster, which had the feel of a FWD although it handled like an AWD with ease. However, as everything is not without fault, so is the TT. Let's take a look at some of the more common problems associated with it.
A lot has been said about the faulty nature of the timing belt in Audi's 2002 and 2003 models. One case even mentioned about driving an Audi through and through, and then breaking at 59,000 mi. This is very far from the 105,000 mi replacement for owners, and this obviously was a cause of frustration for the owner who wanted to replace his timing belt with original Audi TT Quattro parts.
This was attributed to a design flaw in the models of the Audi TT timing belts, a shared flaw with the Audi A4. It was the subject of a lawsuit in 2007, and had prompted Audi to pay for damage and compensation for damages related to the timing belt problem.
The control arm is one part of a car that should not be overlooked. It was also the subject of a recall for the 2000 and 2001 models of the TT Quattro. In April of 2002, Audi began the recalls of those TT models because of this problem with the control arm. The control arms are subject to corrosion, and this may impede their proper movement which could lead to grave results. Corrosion may occur due to moisture entering the rear track control arm's mounting bushing and bolt combination.
One of the most common problems that is often cited about the TT Quattro is the constant illumination of the 'Check Engine' light. This light is an indication of any number of problems that may have something to do with the Audi's components. Usually the cause of this is due to vacuüm leaks, the oxygen sensor, or a fault with the catalytic converter.
More commonly, it is due to the failure of the air pump and air valve. Failure of these components lets the car's system attribute the fault to a vacuüm leak problem. This is caused by a poorly pressurized fuel tank, a result of the failure of the air pump and valve.
Other common problems with the TT Quattro include some issues with the interior side trim panels. These may become detached if the C-pillar trim covers fail to work properly. While it may not do that much harm to the car, the problem this time lies with the potential danger it could cause to a passenger, prompting a recall and replacement with Audi TT Quattro parts.
