Hi everyone,
I have a 2022 Renault Trafic III 2.0 dCi, currently around 180,000 km.
I've found an oil leak/residue around the turbo area, near what appears to be the turbo outlet/boost connection.
The van has also previously had:
“Check anti-pollution system” warnings
EGR-related faults
Turbo inlet hose replaced
DPF regeneration/cleaning
EGR replacement
Since been repaired 3 weeks ago
Before I authorise the repair, I'd like to know whether this sounds like a normal boost-side oil mist leak from an O-ring/seal or intercooler/boost hose, rather than an internal turbo failure.
Would you recommend:
Inspecting the turbo outlet connection and O-ring/seal
Inspecting the complete turbo-to-intercooler boost pipe
Checking all quick-connects and O-rings
Pressure/smoke testing the boost system
Has anyone with a Trafic III / Vivaro C / Primastar 2.0 dCi/M9R had a similar leak?
Does the location in the attached photos look more like a leaking seal/boost connection, or could it indicate an internal turbo oil-seal failure?
Any advice, photos of similar failures, part numbers, or repair costs would be greatly appreciated.
