Audi Diesel Engine Repair in Espoo
Modern diesel engines have many advantages: high torque, fuel efficiency, durability, etc. In addition, they are not affected by gasoline engine problems such as spark plug or ignition coil failures. However, TDI engine diagnostics and repair require higher engine expertise and a wide range of special tools.
At our Volkkarihuolto service center in Espoo, you can get professional diagnostics and repair of diesel engines for all Audi models.
Main Malfunctions
Many Audi diesel engines are equipped with Bosch VR-44 high-pressure fuel pump. This component is electronically controlled and has two-stage injectors and a control unit for regulating valves. All these fuel injection pump parts are lubricated by fuel, and if you decide to save money and use less lubricating fuel, you may face mechanical damage to the fuel injection pump.
Problems manifest as follows
- Difficulty starting the engine (especially if the fuel is already hot)
- Poor acceleration dynamics
- Increased smoke emission
What We Check and Repair
- Diagnostics and repair of high-pressure fuel pump
- Replacement of mass air flow sensor
- Engine sensor check
- Diagnostics of actuator components
- Crankcase ventilation system check
- Oil quality and change interval check
- Timing chain condition check
Prevention and Diagnostics
To prevent frequent powertrain failures, we recommend carefully selecting maintenance supplies. For example, all TDI series engines are very sensitive to oil quality. If oil changes are not performed on time or lower quality oil grades are used, the timing chain wears out quickly.
