Common Audi Q3
Malfunctions near Brooklyn, NY

Leaking Water Pump and Thermostat Housing

Audi Q3 45 Premium and Premium Plus vehicles that have EA888 engines often report a malfunction in the housing unit of the integrated water pump and thermostat. The housing unit is made up of a plastic polymer composite, which gets degraded after experiencing thousands of heat cycles. This results in the formation of cracks, which, if they progress, cause leaks. Coolant puddles under the vehicle, a distinct coolant smell, a low coolant level, and engine overheating are the signs of leaks in the water pump and thermostat. As a result of the leak, the engine overheats, causing component corrosion and heat-related damage in your Audi Q3 45 Premium and Q3 45 Premium Plus near Brooklyn.

At our auto repair shop, Bay Diagnostic, a diagnostic inspection determines the cause and origin of the malfunction. The process includes the visual inspection, pressure test of the cooling system, and diagnostic scanning of temperature sensors. The repair process begins with draining the coolant and disassembling the intake manifold, serpentine belt, and belt tensioner. Then the damaged housing is removed and the mount is properly cleaned. A new OEM-made integrated water pump and thermostat unit has been installed, and the components have been reassembled. After finishing the repairs, the components are reinstalled, and the coolant is refilled to an adequate level in Brooklyn.

Carbon Build Up in Intake Valves

In modern TFSI engines of the Audi Q3, the fuel is directly injected into the intake manifold at high pressure. In traditional fuel injection, the back of the intake valve is cleaned due to the flow of oil; however, this does not occur in newer models of the Audi Q3 45 Premium Plus. Oil vapour from the PCV condenses and sticks to the opening of the valve. Heat burns the oil and causes carbon buildup on the intake valve in your Audi near Brooklyn.

At Bay Diagnostic, the diagnostic procedure involves conducting a diagnostic scan for misfire or fuel trim-related fault codes, as well as a borescope inspection of the cylinder interior. The repair begins with the intake manifolds and fuel rail, as well as rotating the camshaft. Then ‘Walnut Blasting’ is conducted, where walnut shells are propelled at a high speed onto the buildup, removing them completely without damaging the engine interior of the Audi Q3 45 Premium Plus near Brooklyn.

Tronic (DSG) Mechatronics Unit Failure

The internal failure of the mechatronic unit, which houses the transmission components, could occur due to internal circuit board cracks caused by heat and vibration, solenoid failure, or contamination of the hydraulic fluid in the Audi Q3 45 Premium. The resulting transmission failure causes transmission malfunctions, including harsh shifting, gear slipping, and loss of driving stability. This decreases the drivability and safety of the vehicle in the vicinity of Brooklyn.

Specialized diagnostic scanners, such as VAG-COM (VCDS) or factory ODIS, are used by our technicians at Bay Diagnostic to access the transmission control unit and identify malfunctions. The damaged mechatronic is removed from the vehicle and repaired. Its components are either repaired or replaced according to the extent of damage. The re-manufactured unit is then installed, finishing the repair. Then, the vehicle’s OBD system is reset, and the transmission fluid is refilled in the Audi Q3 45 Premium near Brooklyn.
