Disadvantages of the B4204T35 engine
In the early years of production, there were numerous instances of rubber pipe cracking; the majority of owner complaints on specialized forums are related to oil consumption;
The fuel injectors need to be cleaned once every 60,000 kilometers to prevent failure;
Every 120,000 kilometers, replace the timing belt because the valves bend here when it breaks;
Oil seal leaks are another frequent issue with these engines.
