Disadvantages of the Audi ARE engine
- First of all, this is a very heat loaded motor, so keep an eye on cooling;
- As luck would have it, this unit does not have a reliable water pump and thermostat;
- A lot of trouble for the owner is the search for an oil leak and air leaks;
- Turbines have a rather modest resource, often they run less than 100 thousand km;
- It is better to change the timing belt every 60,000 km, since when it breaks, the valves bend;
- Do not forget to update the chains every two belt changes, their jumping is also dangerous;
- Another weak point of the engine include a heat exchanger, viscous coupling, ignition coils.
