New left turbo, no replacements, for Audi A4 type S4 (B5)

For A4 (B5):
- S4 2.7 V6 265 hp (AGB, AZB)

It is highly recommended to replace both turbos on these engines at the same time (ref. AD90052 for the right turbo) The following precautions are to be taken when replacing a Turbo charger:
- The oil circuit must be cleaned to ensure that any residues that may block the circuit are removed
- The oil and oil filter must be replaced
- The oil intake and return pipes must be checked and cleaned
- The air hoses and breather must also be checked
- With the help of a syringe, feed oil into the turbo via the oil inlet, then start the turbine manually.
- Once the new turbo is fitted, start the engine and let it tick over for 10 minutes. Before stopping the
engine, let it tick over for a few seconds (do not accelerate brusquely before turning off)
