The engine number B4204T35 is located on the cylinder block. Most of the complaints from owners on the specialized forum are related to oil consumption. In the early years of production, there were many cases of cracking rubber hoses. Fuel injectors need to be cleaned or they will fail every 60,000 km. Change the timing belt every 120,000 km, as if it breaks, it can cause valve damage. Another common issue with these engines is leaking seals.
