Volvo models come from the factory with rubber couplers and can fail after as little as 50,000 miles. Rubber couplers fail from age, heat, and oil soaking from natural oil migration that occurs in turbo charged vehicles. Symptoms of torn or failing couplers include lean running at low throttle and rich running at higher throttle, additionally fuel mileage can suffer greatly. The number one complaint associated with torn or failed couplers is low or erratic boost and subsequent lower power from the vehicle.
