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.

Premature wear in various multi-link suspension components can cause noises that are difficult to diagnose. Worn suspension parts can also cause uneven tire wear and create steering alignment problems.
Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.
The water pump may fail resulting in engine overheating and possible timing belt damage. Overheating and/or timing belt failure can result in very expensive engine repairs. As a precaution, it is recommended to inspect the timing belt and water pump at regular intervals.
Our technicians recommend having the constant velocity (CV) boots and CV joints inspected at each service. Servicing torn CV boots early can prevent the need to replace the CV half shaft or CV joint.

Audi A4 Reviews
great car minimum of repair issues, but when needed they are pricey. recently used repairpal recommended shop great service fair price
I have a love/hate relationship with Audi -- love Audi performance; hate the dealership staff for their arrogance and attitude towards older Audi model drivers. That's why I prefer Asian models over Audi. Audi acts like you're walking into a Saks 5th Ave. store and you'd better look ultra-professional or else you won't get fair treatment. For the fist time in my life, I had to take a service Audi shop to court for crappy work. I lost the small clams suit against them. The repair was rare an unheard of. Presently, I'm in debt with Audi repairs and I don't even have the car anymore. I've never had debt problems after owning any car. NEVER! I'm not the only one that's had problems with this auto maker. Beware of those German cars, though as they can break like crystal.
2008 A4 Convertible had many issue with the ignition coils since new. Replaced same one twice in the first 2 years. now with 26000 miles the convertible top motors going bad, replaced one today. The are not recalled, but they should be since the dealer says they have been having problems with them. Funny they are putting in a different kind of motor, go figure.
I got this car with 50,000 miles on it,it drives like new only thing went out is the fuel pump,
catalytic converter nightmares!!!!!!!!!!!!!!
