Disadvantages of the Audi BFM engine
- Despite the aluminum block, seizures in the cylinders are rare here.
- However, with savings on oil and frequent overheating, they will not keep you waiting.
- Most of the problems here are delivered by unreliable hydraulic timing chain tensioners.
- Try to monitor the condition of the timing belt, or if it breaks, the valves will bend.
- Oil leaks are also common, especially at the junction of the engine with the gearbox.
